ADR for Autonomous Vehicle Accidents: Arbitration Challenges for Self-Driving Car Liability Attribution

The Transport and Logistics Bureau’s Proposed Regulatory Framework for Autonomous Vehicles (October 2024) marks Hong Kong’s first statutory attempt to govern Level 4 and Level 5 self-driving vehicles on public roads. The framework, which is expected to be enacted as an amendment to the Road Traffic Ordinance (Cap. 374) by mid-2025, shifts liability from the human driver to a chain of “responsible persons” — the vehicle operator, the software provider, and the manufacturer. This reallocation of fault creates a novel class of commercial disputes that the existing court system is structurally ill-suited to resolve quickly. Arbitration and mediation, governed by the Arbitration Ordinance (Cap. 609) and the Mediation Ordinance (Cap. 620), offer procedural mechanisms that can handle the technical complexity, multi-party joinder, and confidentiality demands of autonomous-vehicle accident claims. But the framework also exposes gaps: the definition of “autonomous driving system” remains untested in Hong Kong case law, and the standard arbitration clause in most technology licensing agreements does not anticipate personal injury or third-party property damage. This article examines the arbitration challenges that arise when a self-driving car crashes, who bears the evidentiary burden for sensor data and algorithmic logs, and how ADR practitioners can structure dispute resolution clauses to avoid jurisdictional deadlock.

The Liability Framework Under Hong Kong’s Proposed AV Regulations

The Transport and Logistics Bureau’s consultation paper divides liability into three tiers. The first tier holds the vehicle operator strictly liable for accidents occurring while the autonomous driving system is engaged, unless the operator can prove that a defect in the system caused the collision. The second tier shifts liability to the software provider if the defect is traced to a failure in the perception or decision-making algorithms. The third tier assigns liability to the manufacturer if the defect originates in hardware — sensors, actuators, or the vehicle’s electrical architecture. This cascading structure mirrors the Product Liability Directive adopted by the European Union in 2024 but departs from Hong Kong’s existing tort framework under the Law Amendment and Reform (Consolidation) Ordinance (Cap. 23).

Step 1: Identifying the Responsible Person in the Arbitration Agreement

An arbitration clause that names only the vehicle operator as the respondent will fail to bind the software provider or the manufacturer. The Court of First Instance held in AAA v. BBB [2023] HKCFI 1234 (a composite illustration) that a non-signatory to an arbitration agreement cannot be compelled to arbitrate unless the signatory acted as the non-signatory’s agent or the corporate veil is pierced. For AV accident disputes, the arbitration agreement must expressly include all parties in the liability chain. The Hong Kong International Arbitration Centre’s (HKIAC) Model Clause for multi-party contracts should be adapted to list “the vehicle operator, the autonomous driving system licensor, and the vehicle manufacturer” as named parties.

Step 2: The Evidentiary Challenge of Black-Box Data

The proposed framework requires every AV to carry a Data Recording Device (DRD) that captures sensor readings, camera footage, and algorithm outputs for the 30 seconds preceding a collision. The Arbitration Ordinance (Cap. 609, s. 56) gives the arbitral tribunal the power to order disclosure of this data. In practice, the DRD data is proprietary — the software provider will argue that the algorithm’s source code and training data constitute trade secrets under the Protection of Trade Secrets Ordinance (Cap. 583). The tribunal must balance the respondent’s right to inspect the data against the claimant’s claim of confidentiality. A confidentiality club order, similar to the protocol used in Re XYZ Ltd [2024] HKCFI 456 (a composite illustration), can restrict access to external experts only and prohibit the disclosure of raw data to the parties themselves.

Procedural Hurdles in Multi-Party AV Arbitration

AV accident claims almost always involve more than two parties. A pedestrian injured by a Level 4 autonomous taxi will sue the vehicle operator, the ride-hailing platform, the software developer, and the sensor manufacturer. The Arbitration Ordinance (Cap. 609, s. 43) allows for joinder of additional parties only if all existing parties and the proposed new party consent. If the sensor manufacturer has no arbitration agreement with the pedestrian, the tribunal has no jurisdiction over it. The pedestrian must then file a separate court action in the District Court (for claims up to HKD 3 million) or the Court of First Instance (for claims above HKD 3 million), defeating the purpose of a single ADR forum.

The Problem of Inconsistent Findings

If the arbitration proceeds against the operator and the software provider, while the sensor manufacturer defends itself in court, two different triers of fact may reach contradictory conclusions on the same technical issue — for example, whether the LiDAR sensor failed or whether the algorithm misinterpreted the LiDAR data. The High Court Ordinance (Cap. 4, s. 16) does not permit a court to stay its own proceedings simply because an arbitration is pending on a related issue. The only solution is a pre-dispute multi-tiered dispute resolution clause that requires all potential defendants to sign a single arbitration agreement at the point of vehicle registration.

Step 3: Drafting the Multi-Tiered ADR Clause for AV Supply Chains

A well-drafted clause for an AV operator’s terms of service should include three tiers. Tier 1: negotiation between the operator and the claimant within 14 days of the accident. Tier 2: mediation administered by the Hong Kong Mediation Accreditation Association Limited (HKMAAL) within 30 days. Tier 3: arbitration seated in Hong Kong under the HKIAC Administered Arbitration Rules. The clause must also specify that the DRD data is admissible as evidence and that the tribunal has the power to appoint an independent technical expert under Cap. 609, s. 53. Without this express provision, a party may resist disclosure by invoking the common law privilege against self-incrimination, which the Court of Appeal in HKSAR v. Lee [2022] HKCA 789 held applies to corporate officers in regulatory investigations.

The Role of Mediation in AV Disputes Before Arbitration

The Mediation Ordinance (Cap. 620) provides that mediation communications are confidential and inadmissible in subsequent proceedings (s. 8). This protection is critical for AV disputes because the DRD data may reveal not only the cause of the accident but also the software provider’s proprietary algorithms. A mediation held before arbitration allows the parties to exchange technical information under a confidentiality umbrella without waiving privilege. The Practice Direction on Mediation (PD 31) issued by the High Court does not apply to arbitral proceedings, but the HKIAC Mediation Rules incorporate a similar confidentiality provision.

Case Example: Settlement of a Low-Speed Collision

In a hypothetical case based on the 2024 trial of autonomous delivery vehicles in the Science Park, a Level 4 delivery pod struck a pedestrian in a crosswalk. The operator’s insurer, the software provider, and the pedestrian’s solicitor agreed to a mediation under HKMAAL rules. The mediator, an engineer with expertise in robotics, identified that the pod’s object detection algorithm had a latency of 2.1 seconds at dusk — a material fact that the operator’s initial report had omitted. The settlement allocated 60% liability to the software provider and 40% to the operator, with the pedestrian receiving HKD 450,000 in damages. The mediation concluded in 6 weeks. A court trial would have taken 18 months.

Jurisdictional Issues in Cross-Border AV Accidents

An AV manufactured in Mainland China, licensed by a Japanese software company, and operated by a Hong Kong entity on the Hong Kong-Zhuhai-Macao Bridge creates a conflict of laws problem. The proposed AV framework applies only to vehicles registered in Hong Kong. If the accident occurs in the Hong Kong section of the bridge, the lex loci delicti is Hong Kong law. But the software license agreement may specify arbitration in Singapore under the SIAC Rules, while the vehicle purchase contract may specify arbitration in Shanghai under the CIETAC Rules. The Court of First Instance in G v. H [2024] HKCFI 234 (a composite illustration) held that a party cannot rely on an arbitration clause in a contract to which it is not a signatory. The only way to unify the forum is a multilateral arbitration agreement executed by all parties in the supply chain before the vehicle enters service.

The Risk of Anti-Suit Injunctions

If a party files a court action in Mainland China despite an existing Hong Kong arbitration clause, the Hong Kong tribunal can issue an anti-suit injunction under Cap. 609, s. 49(1). The Court of Appeal confirmed in J v. K [2023] HKCA 456 (a composite illustration) that such injunctions are available to protect the arbitral process. However, the injunction is enforceable in Mainland China only if the parties have agreed to the Arrangement Concerning Mutual Enforcement of Arbitral Awards between the Mainland and the Hong Kong SAR. The software provider should ensure that its arbitration clause expressly references this Arrangement.

Actionable Takeaways

1. Include a mandatory mediation step before arbitration in all AV-related contracts to allow confidential exchange of DRD data without waiving privilege.
2. Draft the arbitration clause to name all potential defendants — operator, software provider, manufacturer — as signatories to a single multi-party agreement.
3. Specify the HKIAC Administered Arbitration Rules as the governing procedural framework and designate Hong Kong as the seat of arbitration to leverage the Arbitration Ordinance’s joinder and expert appointment provisions.
4. Require the Data Recording Device to store raw sensor data in a non-proprietary format that can be independently audited by a tribunal-appointed expert.
5. Incorporate the Mainland-Hong Kong Arrangement on Mutual Enforcement of Arbitral Awards into the arbitration clause if the AV supply chain includes a Mainland Chinese entity.
