From contract.
Through dispute.
To enforceable outcome.

These Rules govern proceedings administered by UNIONE™ where the parties have agreed to use the UNIONE™ International Arbitration & Dispute Resolution Rules, or where they subsequently agree in writing that a matter will be administered under them.

The Rules are designed for cross-border commercial relationships and disputes and may operate at one or more stages of the UNIONE™ lifecycle: prevention, structured resolution, arbitration, award quality review, enforcement readiness and post-award institutional support.

Nothing in these Rules displaces mandatory law, limits a competent court's powers, or creates jurisdiction over a person or claim in the absence of a valid legal basis.

For these Rules: ‘Arbitration’ means an arbitration administered by UNIONE™; ‘Committee’ means the UNIONE™ Case Administration Committee; ‘Secretariat’ means the administrative office responsible for case management; ‘Tribunal’ includes a sole arbitrator or multi-member tribunal; ‘Standing Neutral’ means a neutral appointed under the DPC™ framework; ‘Structured Resolution’ includes mediation, neutral evaluation, expert determination, executive dispute conference and other consensual neutral processes; ‘ERR™’ means Enforcement Readiness Review.

‘Electronic Communication’ includes secure portal transmission, email and another method approved by the Secretariat; ‘Material AI Use’ means use of an artificial-intelligence system to generate, alter, reconstruct or materially analyse evidence, expert analysis, translations, transcripts or authorities in a manner relevant to reliability, authenticity or fairness; ‘Funder’ means a non-party providing material financing or indemnity linked to the outcome of the proceeding.

A reference to a day means a calendar day unless the Rules, a Protocol or a procedural order states otherwise.

These Rules, the applicable UNIONE™ Protocols, any mandatory law at the seat, and procedural orders issued in the matter form the procedural framework of the proceeding.

A Protocol forms part of the Rules when the arbitration agreement expressly incorporates it, when the Rules make it applicable, or when the Tribunal adopts it after consulting the parties. If a Protocol conflicts with these Rules, these Rules prevail unless the Rules expressly provide otherwise.

Practice Notes explain administration but do not amend party rights unless incorporated by agreement or procedural order.

The version of the Rules in force on the date an Arbitration is commenced applies unless the parties agree otherwise or mandatory law requires another result.

A DPC™, Structured Resolution or other pre-arbitration process does not by itself fix the version of the Arbitration Rules applicable to a later arbitration unless the parties expressly agree that it shall.

UNIONE™ shall maintain a public archive showing each version, its effective date and material amendments.

The institution, Committee, Tribunal and parties shall act consistently with independence, impartiality, procedural fairness, proportionality, reasonable expedition, confidentiality where applicable, and equality of treatment.

Procedure shall be proportionate to the value, complexity, urgency, evidentiary burden and commercial context of the dispute. Efficiency shall not override a party's reasonable opportunity to present its case.

The Tribunal shall seek to avoid unnecessary cost and delay and may take account of procedural conduct when allocating costs.

Parties may agree procedural arrangements that modify these Rules, subject to mandatory law, equality of treatment, tribunal independence and institutional requirements necessary for administration.

The Tribunal may decline to give effect to an agreed procedure that would render the proceeding fundamentally unfair, impossible to administer, or inconsistent with a non-derogable rule of law.

No institutional service, certificate or review constitutes legal advice on the law of any jurisdiction.

Proceedings are digital-first. Documents shall be filed through the designated secure case platform or another method specified by the Secretariat.

A communication is deemed received when it enters the designated electronic system or, if another method is authorised, when it is delivered to the address last notified by the receiving party, subject to proof of transmission failure.

The Secretariat or Tribunal may require hard copies, certified copies, translations, authentication or alternative service where necessary for fairness, legal validity or enforcement.

Time begins on the day after receipt of the relevant communication. If the final day falls on a day on which the designated UNIONE™ administrative office is closed, the period ends on the next working day, without affecting a time limit imposed by mandatory law.

The Secretariat may extend administrative time limits before the Tribunal is constituted. The Tribunal may extend or shorten procedural time limits after consultation with the parties when fairness and efficiency permit.

A party seeking relief from a missed time limit shall act promptly and explain the circumstances and any prejudice.

The parties may agree the legal seat of arbitration. Failing agreement, the Committee shall designate a provisional seat after considering the parties' submissions, relevant connections, enforceability and neutrality; the Tribunal may confirm or, for compelling reasons and after consultation, recommend modification subject to law.

The legal seat is distinct from the physical or virtual place of hearings. Hearings may occur in any location or by secure remote means without changing the seat.

The arbitration is subject to the mandatory procedural law of the seat.

The Secretariat administers filings, communications, deposits, logistics, case records and routine procedural administration. It does not decide the merits.

The Case Administration Committee determines institutional matters assigned to it by these Rules, including appointments where required, arbitrator challenges, consolidation before constitution, procedural-track decisions where no Tribunal exists, and other institutional questions.

Committee members deciding a matter must be independent of the parties and dispute and free from material conflict. A person’s Fellowship, professional standing or governance role creates no entitlement, priority or expectation of appointment in any case.

The Committee may act through panels of three or more conflict-cleared members and may delegate routine non-discretionary administration to the Secretariat.

A party may enter UNIONE™ through contract intelligence, DPC™, Structured Resolution or Arbitration. Entry at one stage does not create consent to another adjudicative process unless such consent exists independently.

In particular, participation in prevention, mediation, neutral evaluation or expert consultation does not by itself constitute consent to arbitration.

The Secretariat shall identify the legal basis relied upon for each stage of administration.

Parties may adopt the UNIONE™ Dispute Prevention Certificate framework in a contract, amendment or separate agreement.

The DPC™ may record agreed prevention checkpoints, escalation steps, relevant jurisdictions, notice mechanics, milestone triggers, confidentiality rules and the role of a Standing Neutral.

A DPC™ is a prevention framework. It is not a guarantee that disputes will not arise and does not determine substantive rights unless the parties expressly confer a defined determinative power.

Unless the parties agree otherwise, the DPC™ framework may address: clause integrity; governing-law and seat alignment; enforcement-jurisdiction mapping; milestone and trigger definitions; confidentiality and privilege architecture; and escalation integrity.

The Secretariat may maintain an administrative record showing completion of agreed checkpoints without publishing confidential commercial information.

A checkpoint assessment is advisory unless the parties expressly agree otherwise.

Where the parties adopt a Standing Neutral mechanism, the neutral shall be appointed in accordance with the agreed method or, failing agreement, by the Committee after conflict and availability review.

The Standing Neutral must disclose circumstances reasonably capable of giving rise to justifiable doubts as to independence or impartiality and must continue to disclose throughout the appointment.

The role, duration, retainer, response times, authority and fee basis of the Standing Neutral shall be recorded in writing.

The DPC™ agreement may identify Trigger Events including material delay, payment default, change-order impasse, deadlock, repeated notice failure, performance dispute, threatened termination, data or technology incident, or another agreed event.

Upon a valid activation request, the Standing Neutral shall ordinarily convene the first procedural contact within 72 hours or another period specified in the DPC™ Protocol.

Activation does not suspend contractual or statutory rights, limitation periods or court remedies unless the parties' agreement or applicable law provides otherwise.

A Standing Neutral may facilitate communication, request concise position papers, identify issues, recommend process steps, conduct neutral evaluation where authorised, and assist the parties in selecting a resolution route.

The Standing Neutral may not impose a binding decision unless the parties have clearly agreed in writing to a defined determinative function and the applicable law permits it.

The Standing Neutral shall avoid unnecessary formality and focus on preserving the commercial relationship where practicable.

Prevention communications designated confidential or without prejudice shall remain protected to the fullest extent permitted by applicable law.

A later Tribunal shall not receive settlement positions, concessions, confidential neutral evaluations or privileged prevention communications unless all affected parties consent or applicable law requires disclosure.

Objective records that existed independently of the prevention process do not become inadmissible merely because they were used during prevention.

If prevention does not resolve the matter, the parties may proceed to Structured Resolution, Arbitration, court relief or another agreed mechanism.

The Secretariat may carry forward administrative information necessary to avoid duplication, but shall segregate without-prejudice and privileged materials.

Any prior neutral who may be proposed for a later adjudicative role is subject to Article 19 and the applicable conflicts standard.

A Standing Neutral, mediator, evaluator or other settlement neutral shall not serve as arbitrator in the same or a substantially related dispute unless, after the dispute has arisen and after full disclosure, all parties provide informed written consent and applicable law permits the appointment.

Even with consent, the proposed arbitrator must determine independently whether prior knowledge or involvement would impair actual or perceived impartiality.

No adverse inference may be drawn from a party's refusal to consent.

Structured Resolution may include mediation, neutral evaluation, expert determination, executive dispute conference, facilitated negotiation, technical conference or another consensual process approved by UNIONE™.

The parties may combine procedures sequentially or in parallel if roles, confidentiality and decision authority are clearly separated.

A determinative procedure such as expert determination requires a clear written grant of authority and shall be governed by the agreed terms and applicable law.

A Structured Resolution begins when the Secretariat receives a joint request, or a unilateral request where an existing agreement permits unilateral commencement, together with the information required by the applicable Protocol.

The Secretariat shall notify the other party, identify the procedure proposed, confirm the applicable confidentiality framework and arrange appointment of the neutral.

Participation remains voluntary except to the extent an enforceable contractual step requires participation.

The neutral shall be independent and impartial and shall disclose relevant circumstances before accepting appointment and throughout the process.

The neutral may hold joint or separate sessions, request concise materials, test settlement assumptions, identify missing information and structure proposals, subject to the agreed procedure.

Unless expressly authorised, the neutral has no power to compel evidence, bind a party on the merits or make findings admissible in a later arbitration.

A settlement may be recorded in a written agreement signed by the parties. Where an Arbitration has already commenced and the Tribunal considers it lawful and appropriate, the parties may request a consent award reflecting agreed terms.

The Tribunal is not required to issue a consent award that appears unlawful, impossible to perform, inconsistent with public policy, or beyond the Tribunal's jurisdiction.

The terms of any settlement remain confidential unless disclosure is required for implementation, enforcement, law or regulation.

Unless otherwise agreed, the costs of prevention and Structured Resolution are borne in equal shares as they arise, without prejudice to a later agreement on allocation.

The Secretariat shall close the process upon settlement, written withdrawal, expiry of an agreed period, the neutral's determination that continuation is no longer useful, or transition to another agreed stage.

Closure of a pre-arbitration process does not determine jurisdiction, liability or costs in a later Arbitration.

An Arbitration is commenced by filing a Notice of Arbitration with the Secretariat and paying the required filing fee or obtaining an approved fee arrangement.

The Notice shall identify the parties and representatives, the arbitration agreement relied upon, the contract or legal relationship, the claims and relief sought so far as known, the amount in dispute where quantifiable, proposed seat and language, proposed procedural track, and any requested emergency, joinder, consolidation or coordinated-proceeding relief.

The claimant shall provide sufficient contact and service information to permit prompt notification.

The Secretariat shall review the filing for administrative completeness and register the case when the minimum requirements are satisfied.

Registration is an administrative act and does not constitute a final decision that a valid arbitration agreement exists, that a claim is admissible, or that UNIONE™ has jurisdiction to administer every issue raised.

The Secretariat may request clarification, separate incompatible claims for administrative purposes, or refer a threshold institutional issue to the Committee.

The respondent shall file a Response within the period fixed by the Rules, Protocol or Secretariat, ordinarily 21 days after receipt of the Notice unless a different track applies.

The Response shall state preliminary positions on jurisdiction, claims, relief, counterclaims, set-off, seat, language, tribunal constitution, procedural track and any consolidation or joinder issue.

Failure to file a Response does not prevent the Arbitration from proceeding.

Before constitution, a party may amend its case with notice to the Secretariat unless the amendment would require a materially different arbitration agreement or prejudice orderly constitution.

After constitution, amendment requires Tribunal permission, taking into account delay, prejudice, jurisdiction, procedural economy and the stage of proceedings.

The Tribunal may impose conditions, including costs, timetable changes or security, when permitting an amendment.

For institutional purposes, the Arbitration commences on the date the Secretariat receives the Notice and the minimum filing requirements specified in the applicable filing procedure are satisfied.

The effect of commencement on limitation, prescription or time bars is governed by applicable law and the arbitration agreement. UNIONE™ does not certify that a filing interrupts any statutory period.

Where limitation is disputed, the Tribunal shall determine the issue within its jurisdiction.

A claimant may commence a single Arbitration containing claims under more than one contract or arbitration agreement where the claims arise from the same transaction, series of related transactions, integrated project, common commercial relationship or closely connected factual matrix and the arbitration agreements are prima facie compatible.

The Committee may require separate registration where compatibility or jurisdiction is seriously disputed, without prejudging later consolidation or coordination.

The Tribunal retains authority to decide its jurisdiction over each claim.

A party may request joinder of an additional person before or after constitution where that person is prima facie bound by the arbitration agreement, consents to joinder, or another lawful basis for arbitral jurisdiction is asserted.

Before constitution, the Committee decides whether joinder may proceed on a prima facie basis. After constitution, the Tribunal decides after giving all affected persons a reasonable opportunity to be heard.

A decision to join does not finally determine jurisdiction over the joined person unless made by the Tribunal as a jurisdictional decision.

The Committee may consolidate two or more UNIONE™ arbitrations before constitution where all parties agree; the claims arise under the same arbitration agreement; or the disputes arise from the same or related transactions and the arbitration agreements appear compatible.

After constitution, consolidation may be ordered only by the Tribunal with Committee approval where the same Tribunal can lawfully act in the relevant arbitrations or all parties agree.

The decision-maker shall consider procedural stage, tribunal composition, common issues, risk of inconsistent outcomes, efficiency, confidentiality and prejudice.

Where consolidation is unnecessary or inappropriate, arbitrations involving common legal or factual issues may be coordinated.

Coordination may include aligned timetables, joint procedural conferences, common evidentiary steps, sequential determination of common issues, or temporary suspension of one proceeding pending a decision in another.

Unless the parties agree otherwise and the Tribunal has jurisdiction to do so, coordinated arbitrations remain legally separate and produce separate decisions and awards.

No person is bound to arbitrate merely because it is affiliated with, controls, is controlled by, funds, benefits from, or participated in performance of a contract signed by another person.

Jurisdiction over a non-signatory shall be determined according to the arbitration agreement, applicable law and proven facts, including any legally recognised basis by which consent may be established.

The Secretariat and Committee may make only prima facie administrative determinations before the Tribunal is constituted.

If a respondent objects before constitution that no arbitration agreement exists or that a claim falls outside it, the Committee may allow administration to continue where there is a prima facie basis for jurisdiction.

The Committee's decision is administrative, without prejudice to the Tribunal's power to determine jurisdiction and without binding any court competent to review jurisdiction.

If no prima facie basis exists, the Committee may decline or discontinue administration as to the affected claim or person.

The Tribunal may rule on its own jurisdiction, including objections concerning existence, validity, scope or applicability of the arbitration agreement, subject to applicable law.

An arbitration clause is treated as separable from the underlying contract to the extent recognised by applicable law.

The Tribunal may determine jurisdiction as a preliminary issue, in an interim or partial award, or with the merits, taking into account fairness and efficiency.

If a party fails to participate, the proceeding may continue after the Tribunal is satisfied that reasonable notice and an opportunity to be heard were provided.

Default does not relieve the claimant of the burden of establishing jurisdiction and entitlement to relief.

The Tribunal may draw reasonable inferences from unexplained failure to produce ordered evidence, but shall not treat non-participation as an automatic admission of liability.

The parties may agree to a sole arbitrator or a tribunal of three or another odd number permitted by law.

Failing agreement, a sole arbitrator is the default unless the Committee determines that complexity, value, public significance, multiparty structure or another circumstance warrants three arbitrators.

A procedural track may prescribe a sole arbitrator unless the Committee decides otherwise for compelling reasons.

Where the parties have agreed a nomination method, it shall be followed unless it cannot operate fairly or within the required time.

Any nominated arbitrator is subject to confirmation by UNIONE™ after independence, impartiality, availability and competence review.

UNIONE™ may appoint from its Panel or outside it where appropriate. Fellowship or Panel status does not guarantee appointment; a party may nominate a suitably qualified person who is not a Fellow unless the arbitration agreement expressly restricts eligibility.

If the parties or co-arbitrators do not agree the sole arbitrator or chair within the applicable period, the Committee shall appoint.

The Committee shall consider nationality, residence, language, sector competence, legal tradition, availability, diversity, conflicts, seat and any qualifications agreed by the parties.

The Committee may use a list procedure where it considers that process appropriate.

Every arbitrator must remain independent and impartial and have sufficient availability to conduct the case within the applicable timetable.

Before appointment or confirmation, an arbitrator shall disclose any circumstance that might reasonably be considered relevant to independence, impartiality or availability. The duty continues throughout the proceeding.

Failure to disclose does not automatically establish bias but may be considered in challenge, costs or institutional decisions.

A party may challenge an arbitrator for justifiable doubts as to independence or impartiality, lack of agreed qualification, material unavailability, or substantial failure to perform duties.

A challenge shall be filed promptly and ordinarily within 14 days after the party became aware, or reasonably should have become aware, of the relevant facts.

Unless the arbitrator withdraws or all parties agree, a conflict-cleared panel of the Committee shall decide the challenge after providing a fair opportunity for observations.

An arbitrator shall be replaced upon resignation, successful challenge, death, incapacity, or a Committee determination of inability or persistent failure to perform.

The replacement shall ordinarily follow the original appointment method. The reconstituted Tribunal shall decide whether any procedural step should be repeated.

Where a three-member Tribunal loses a member after closure of proceedings and replacement would cause disproportionate delay, the remaining arbitrators may proceed only if all parties agree or the applicable law and Committee authorise it after hearing the parties.

A Tribunal may appoint a secretary only after disclosing the candidate's identity, role, fee basis and relevant conflicts and after giving parties an opportunity to comment.

A secretary may perform organisational, administrative and non-decisional research tasks but may not exercise adjudicative authority, determine issues, assess credibility or draft the Tribunal's reasoning in substitution for the arbitrators' own work.

The Tribunal remains fully responsible for every decision and award.

A party shall promptly notify any change or addition to its representatives.

After constitution, the Tribunal may, after hearing the affected party, refuse or condition a representative change only to the extent reasonably necessary to avoid a material conflict that could threaten tribunal integrity or cause serious unfairness.

The Tribunal shall use the least restrictive measure capable of protecting the proceeding.

A party receiving third-party funding shall promptly disclose the identity of the Funder and, where the Funder is an entity, any person or entity exercising ultimate control where reasonably necessary for conflict checking.

The Tribunal may order further disclosure of a material economic interest, insurer, indemnifier, parent, beneficial owner or funding term only where relevant to conflicts, jurisdiction, security for costs or costs allocation, while protecting legitimate confidentiality.

The duty to update disclosure continues throughout the proceeding.

Representatives shall not knowingly mislead the Tribunal, fabricate evidence or authorities, conceal an ordered material fact, improperly contact an arbitrator, intimidate a witness, or engage in conduct that seriously undermines the proceeding.

After notice and an opportunity to respond, the Tribunal may issue directions, admonitions, exclude improperly obtained procedural advantage, allocate costs, or take another proportionate measure within its lawful authority.

Professional disciplinary matters outside the Tribunal's authority remain for the competent professional or legal body.

The Tribunal shall hold an initial case management conference promptly after constitution, ordinarily within 10 days for Standard cases and sooner for accelerated tracks.

The conference shall address issues in dispute, jurisdiction, procedural track, timetable, evidence, hearing format, confidentiality, cybersecurity, AI or digital-evidence issues, settlement opportunities and enforcement-sensitive formalities.

The Tribunal shall issue a procedural order recording the resulting case architecture.

The Tribunal may tailor procedure to the dispute rather than importing court-style process by default.

Relevant considerations include value, complexity, urgency, number of parties, need for disclosure, expert evidence, technological evidence, public or regulatory sensitivity and likely enforcement environments.

The Tribunal may adopt staged issues, page limits, witness limits, document categories, time-limited hearings and other proportionate measures after hearing the parties.

UNIONE™ provides Streamlined, Simplified, Expedited, Standard and Complex Case tracks, together with Emergency and specialist procedures. The detailed presumptions and target timetables are contained in Protocol A.

The applicable monetary thresholds are those published in the Schedule in force at commencement unless the parties agree another track.

A track is a case-management framework, not a guarantee of completion by a particular date. Due process and mandatory law prevail.

The Streamlined Procedure is intended for low-value or legally focused disputes capable of decision on a compressed record.

It ordinarily uses a sole arbitrator, a single principal submission from each side, limited document production, documents-only determination unless a short hearing is necessary, and a target final award within 60 days after constitution.

The Tribunal may convert the case to another track if complexity or fairness requires.

The Simplified Procedure is intended for smaller commercial disputes requiring more process than the Streamlined track but not full Standard procedure.

It ordinarily uses a sole arbitrator, tightly controlled document production, limited witness and expert evidence, and a target final award within 60–90 days after constitution.

The Tribunal may dispense with an oral hearing where the parties have had a fair opportunity to present their cases and applicable law permits.

The Expedited Procedure is intended for time-sensitive or mid-value disputes and may apply by agreement, published threshold or Committee decision where the arbitration agreement permits institutional track allocation.

It ordinarily uses a sole arbitrator, an accelerated constitution process, early case management, controlled evidence, a short hearing where needed, and a target final award within 90–120 days after constitution.

The Tribunal may vary the timetable for fairness, complexity, jurisdictional issues or events outside reasonable control.

The Standard Procedure is the default where no accelerated or specialist track applies.

The Tribunal shall nevertheless maintain active case management and ordinarily target a final award within 120–180 days after constitution or within another timetable established by procedural order.

Extensions should be reasoned and recorded in the case timetable.

A Complex Case Procedure may be designated for disputes involving exceptional value, multiple contracts or parties, extensive technical evidence, sovereign or regulatory dimensions, parallel proceedings, large data sets or other circumstances requiring bespoke architecture.

The Tribunal shall adopt a written case plan with staged milestones and may use issue sequencing, coordinated expert processes, evidentiary protocols and partial awards.

Complexity does not justify unmanaged delay; the Tribunal shall identify measures to control cost and duration.

The Committee before constitution, and the Tribunal thereafter, may convert a matter between procedural tracks after consulting the parties.

Conversion may be based on value, complexity, urgency, joinder, new claims, evidentiary burden, fairness, proportionality or another material change.

Existing procedural steps remain effective unless the Tribunal orders otherwise.

The Tribunal may determine a discrete issue of law, fact, contract interpretation, jurisdiction or procedure at an early stage where doing so is likely materially to reduce cost, narrow issues, facilitate settlement or accelerate final resolution.

A party may apply for preliminary determination, or the Tribunal may propose it after giving the parties an opportunity to comment.

The decision may take the form of an order, interim award or partial award as appropriate.

A party may seek early dismissal of a claim, defence or jurisdictional position that is manifestly without legal or factual merit, manifestly outside the Tribunal's jurisdiction, or legally incapable of producing the relief sought even if assumed facts are proved.

The Tribunal shall decide promptly whether the application should proceed and shall adopt a compressed process that preserves a reasonable opportunity to respond.

Abusive early-dismissal applications may be reflected in costs.

The Tribunal may bifurcate or sequence jurisdiction, liability, quantum, limitation, technical, contractual or other issues where likely to improve fairness or efficiency.

It shall consider whether the issue is genuinely separable, the probability of time or cost savings, evidentiary overlap, delay risk and effect on settlement.

Bifurcation shall not be used mechanically merely because a jurisdictional objection has been raised.

After constitution, the Tribunal may order interim or conservatory measures it considers necessary and lawful, including preservation of assets or evidence, maintenance of status quo, confidentiality protection, security, or prevention of conduct threatening the arbitral process.

The Tribunal may require security and may modify or discharge a measure as circumstances change.

Seeking urgent relief from a competent court is not inconsistent with the arbitration agreement or these Rules.

Before constitution, a party may apply for an Emergency Arbitrator where urgent relief cannot await the Tribunal.

The Secretariat shall seek appointment of an independent Emergency Arbitrator as soon as practicable, ordinarily within 24 hours after receipt of a complete application and required payment.

The Emergency Arbitrator shall establish an immediate timetable and ordinarily issue a reasoned order within 10 days after receiving the file, subject to a short extension where necessary for fairness or complexity.

The later Tribunal may modify, terminate or revoke emergency relief and is not bound by findings of the Emergency Arbitrator.

In exceptional circumstances, an Emergency Arbitrator may issue a temporary preliminary order without prior notice where giving notice would create a serious and imminent risk that the purpose of the requested emergency relief would be frustrated.

Any such order shall be narrowly tailored, shall not finally determine substantive rights, and shall be communicated to the affected party promptly after issuance.

The affected party shall receive an immediate opportunity to be heard, after which the Emergency Arbitrator shall confirm, modify or discharge the order.

The Tribunal may order a claimant or counterclaimant to provide security for costs in exceptional circumstances.

Relevant factors include ability and willingness to satisfy an adverse costs award, available assets, conduct, the effect of security on access to arbitration, the apparent strength of the request, and any material funding arrangement. Third-party funding alone is not sufficient.

An order shall specify amount, form and time for compliance. Persistent non-compliance may result in suspension and, after warning, dismissal of the affected claim without prejudice to applicable law.

Each party bears the burden of proving facts on which it relies, subject to applicable law and any different allocation agreed by the parties.

The Tribunal determines the appropriate standard of proof in light of the applicable law, nature of the allegation and circumstances of the case.

No heightened standard shall be presumed solely because an allegation concerns fraud, corruption, bad faith or misconduct, unless applicable law requires it.

Document production shall be targeted and proportionate. Broad discovery is not presumed.

The Tribunal may require specific documents or narrow categories shown to be relevant and material, reasonably identifiable and not unduly burdensome to produce.

The Tribunal shall protect privilege, confidentiality, personal data, trade secrets and legally restricted information through appropriate measures.

A party that reasonably anticipates a dispute shall take proportionate steps to preserve material evidence within its control where required by law, contract, DPC™ obligation or Tribunal order.

The Tribunal may draw an adverse inference where a party, without satisfactory explanation, fails to preserve or produce evidence it was required to preserve or produce.

Any inference must be proportionate and considered with the entire evidentiary record.

The Tribunal may receive written witness statements, oral testimony, party-appointed expert evidence and Tribunal-appointed expert evidence.

The Tribunal may direct witness or expert conferencing, issue-specific expert meetings, joint statements of agreement and disagreement, or technical tutorials where useful.

A witness may be examined remotely where reliability and fairness can be protected.

Electronic records, messages, platform data, logs, metadata, audio, video and machine-generated records are admissible subject to relevance, materiality, authenticity and applicable law.

Where authenticity is disputed, the Tribunal may order production of metadata, hashes, source records, device information, chain-of-custody material or expert verification.

The Tribunal may exclude or give reduced weight to digital evidence whose provenance or integrity cannot reasonably be established.

A party shall not knowingly submit materially fabricated, synthetically generated or deceptively altered evidence without clear disclosure of its nature and purpose.

Where deepfake, synthetic-media or material-alteration risk is raised on a credible basis, the Tribunal may order forensic verification, source production, chain-of-custody review or other authentication measures.

Knowingly presenting fabricated evidence may lead to adverse inferences, costs consequences and other lawful procedural sanctions.

A party and its representatives remain fully responsible for every submission, authority, factual assertion, translation, calculation and exhibit filed in the proceeding, regardless of whether AI tools were used.

Routine drafting, research or organisational assistance need not be disclosed unless the Tribunal orders otherwise. Material AI Use affecting evidentiary authenticity, expert methodology, translation reliability, reconstruction of facts, or another issue material to fairness shall be disclosed to the extent directed by the Tribunal or Protocol F.

No party may rely on a citation, quotation, authority or factual source generated by AI without taking reasonable steps to verify its existence and accuracy.

The Tribunal may use secure technological tools for administrative organisation, search, chronology, translation or similar support only if confidentiality, data security and independent adjudicative judgment are preserved.

The Tribunal shall not delegate decision-making, credibility assessment, weighing of evidence, legal conclusions or award reasoning to an AI system.

UNIONE™ shall maintain internal controls governing approved systems, confidentiality, retention and human oversight.

The parties, Tribunal and Secretariat shall adopt proportionate cybersecurity and data-protection measures having regard to sensitivity, applicable law, cross-border data restrictions, trade secrets and the risk profile of the case.

The Tribunal may order use of designated platforms, access controls, encryption, redaction, secure data rooms, data-localisation arrangements or restrictions on external AI systems.

A material data or cybersecurity incident affecting the proceeding shall be reported promptly to the Secretariat and Tribunal, subject to legal restrictions, so that protective steps may be taken.

Hearings may be physical, virtual, hybrid or documents-only as the Tribunal determines after consulting the parties and considering fairness, efficiency, witness reliability, accessibility, security and applicable law.

The Tribunal may set protocols for witness sequestration, remote-room integrity, interpretation, transcription, recording, screen sharing, exhibits and technical failures.

No hearing shall be publicly broadcast or recorded beyond the official record without Tribunal approval and party consultation.

Unless the parties agree otherwise, or disclosure is required by law, regulation, professional duty, funding disclosure, insurance, enforcement or protection of a legal right, the existence and non-public materials of the proceeding shall be treated as confidential by UNIONE™, the Tribunal and participants under their control.

The Tribunal may issue confidentiality orders tailored to trade secrets, personal data, state-sensitive material, commercially sensitive information or protected technology.

UNIONE™ may publish anonymised procedural data and may publish an award or extract only with party consent or after robust anonymisation and a determination that publication does not prejudice legitimate confidentiality interests.

The Tribunal shall apply the substantive law or rules of law chosen by the parties. Failing a valid choice, it shall apply the law or rules of law it considers appropriate under the applicable conflict-of-laws framework.

The Tribunal shall decide in equity or as amiable compositeur only if expressly authorised by the parties and permitted by the applicable law.

The Tribunal shall have regard to the contract and relevant trade usages where appropriate.

The Tribunal may issue procedural orders, jurisdictional decisions, interim awards, partial awards, consent awards and final awards as appropriate.

An award shall be in writing, state the seat, date and reasons unless the parties validly waive reasons or applicable law permits otherwise, and be signed in the manner required by law.

Where arbitrators do not act unanimously, the award may be made by majority where permitted by law and the reasons for any absent signature shall be recorded.

The Tribunal shall declare proceedings closed when satisfied that the parties have had a reasonable opportunity to present their cases and no further material is required.

The Tribunal shall target issuance of the final award within 30 days after closure in accelerated tracks and 60 days in Standard or Complex cases, subject to justified extension approved administratively by UNIONE™.

The Tribunal may reopen proceedings before the award where necessary to prevent material unfairness or address a decisive new issue.

Before issuance, a draft award shall be submitted to UNIONE™ for a limited institutional quality review focused on form, internal consistency, completeness of dispositive relief, clerical accuracy, procedural history, mandatory formalities and identifiable enforcement-sensitive defects.

UNIONE™ may draw issues to the Tribunal's attention and may require correction of institutional or formal requirements, but shall not substitute its view on facts, credibility, law, jurisdiction or merits.

The Tribunal retains sole adjudicative responsibility for the award.

Following or alongside Article 78 review, UNIONE™ may conduct an ERR™ focused on foreseeable recognition and enforcement risks in jurisdictions identified by the parties or reasonably apparent from the case record.

ERR™ may consider formal validity, notice and due-process record, seat and governing-law consistency, scope of relief, reasoning clarity, party identification, authority, public-policy risk flags, currency and interest clarity, and other matters relevant to recognition or execution.

ERR™ is advisory to the Tribunal on form and enforceability risk. It does not guarantee recognition or enforcement, does not replace local legal advice, and does not authorise UNIONE™ to alter the Tribunal's merits decision.

UNIONE™ may issue an Enforcement Readiness Certificate confirming completion of the review. The certificate is not a legal opinion that the award is enforceable in any jurisdiction.

Within 30 days after receipt of an award, a party may request correction of clerical, computational or typographical error; interpretation of a specific dispositive ambiguity where permitted; or an additional award on a claim presented but omitted from the award.

The Tribunal shall provide the other party a reasonable opportunity to comment and shall decide promptly.

The Tribunal may correct an obvious clerical or computational error on its own initiative within the period permitted by applicable law.

The costs of Arbitration include UNIONE™ administrative charges, Tribunal fees and expenses, approved Tribunal-secretary or expert costs, hearing and technology costs, and other costs designated by the applicable Schedule.

The Tribunal may allocate costs having regard to outcome, reasonableness of legal and expert costs, procedural conduct, settlement conduct where legally permissible, compliance with orders and other circumstances it considers relevant.

Cost allocation shall not penalise a party merely for pursuing a good-faith claim or defence that ultimately fails.

The Tribunal may award pre-award and post-award interest where legally available, at a rate and on a basis it considers appropriate under the applicable law and parties' agreement.

The award should identify the principal amount, rate, compounding basis if any, commencement date and end date or continuing mechanism with sufficient clarity for enforcement.

Interest shall not be structured in a manner prohibited by applicable law.

Awards are binding on the parties subject to any remedy available under applicable law.

The Secretariat may, at a party's request, facilitate administrative transmission of certified copies, payment instructions, compliance confirmations or a short voluntary-compliance period without reopening the merits.

Voluntary compliance discussions after award are confidential unless the parties agree otherwise or disclosure is required for enforcement or law.

UNIONE™ may provide certified copies, procedural-history confirmations, administrative attestations, document authentication coordination and jurisdiction-neutral enforcement information after an award.

Where domestic-law advice, court representation, asset tracing or compulsory execution is required, parties should engage appropriately qualified professionals in the relevant jurisdiction.

Post-award support does not make UNIONE™ counsel to a party and shall preserve institutional neutrality.

At a party's request, UNIONE™ may provide or coordinate separate jurisdiction-intelligence or enforceability-opinion services outside the Tribunal's merits function.

Such services shall clearly identify assumptions, jurisdiction, date, source limitations, whether local counsel has been involved, and whether the output is informational or a legal opinion by a qualified professional.

Nothing in these Rules limits a party's right to seek recognition, enforcement, annulment, set-aside, resistance to enforcement or other post-award relief under applicable law.

Where sanctions, insolvency, export controls, sovereign or state-entity status, immunity, regulatory orders, criminal investigations or another mandatory-law constraint materially affects the proceeding, the Secretariat or Tribunal may require focused submissions and adapt procedure lawfully.

Nothing in these Rules constitutes a waiver of state, sovereign or execution immunity or creates one where none otherwise exists.

The Tribunal shall seek to preserve procedural fairness while avoiding orders that require unlawful conduct.

The existence of parallel court, regulatory, insolvency, criminal or arbitral proceedings does not automatically suspend an Arbitration.

The Tribunal may coordinate, stay, sequence or continue proceedings after considering jurisdiction, risk of inconsistent decisions, prejudice, evidence, urgency and applicable law.

A party shall promptly disclose a parallel proceeding that materially affects jurisdiction, relief, evidence or enforceability.

The Committee may issue decisions with or without full reasons depending on the nature of the issue, confidentiality, urgency and the Rules; challenge, consolidation, joinder and other material contested decisions should ordinarily state concise reasons unless law or party agreement provides otherwise.

Institutional decisions are administrative unless the Rules expressly characterise them otherwise.

A clerical or accidental error in an institutional decision may be corrected on notice to affected parties.

The Secretariat may request advances on costs and may allocate provisional shares among parties without prejudging final cost allocation.

If a party fails to pay its share, another party may pay without waiving any right to seek recovery. The Secretariat or Tribunal may suspend affected claims after reasonable notice.

Persistent non-payment may lead to administrative termination of affected claims without prejudice to refiling where legally permissible.

A party that knows of a non-compliance with these Rules, an agreed procedure or a procedural order and proceeds without timely objection may be deemed to have waived the right to object to that non-compliance to the extent permitted by applicable law.

Waiver shall not be inferred from silence where the relevant rule or right is non-waivable under applicable law.

The Tribunal shall consider whether the party had sufficient knowledge and opportunity to object.

To the fullest extent permitted by applicable law, UNIONE™, its officers, Committee members, Secretariat personnel, arbitrators, emergency arbitrators, mediators and appointed neutrals are not liable for acts or omissions in connection with a proceeding except to the extent liability cannot lawfully be excluded.

Nothing in this Article excludes liability for fraud, wilful misconduct or another category that applicable law prohibits from exclusion.

The parties remain responsible for obtaining independent legal advice on rights, remedies, limitation, enforcement and mandatory law.

UNIONE™ has authority to interpret these Rules for institutional administration before constitution; the Tribunal interprets them for the conduct of the Arbitration after constitution, subject to institutional powers expressly reserved by the Rules.

UNIONE™ may amend the Rules prospectively after institutional review. Material amendments shall be versioned and publicly identified.

These Rules should undergo periodic legal, procedural, cybersecurity, technology and enforceability review to remain fit for cross-border disputes while preserving fairness and party autonomy.
