The line of cases beginning with the Constitution Bench in Cox & Kings Ltd v. SAP India Pvt Ltd on the Group of Companies doctrine (judgment of 2023) [VERIFY exact citation and paragraph numbers] continues to be applied. The line of cases on the binding character of the Section 29A timeline ceiling continues to evolve [VERIFY most recent pronouncements].

Part IV — Institutional trends
Leading institutions continue to publish diversity statistics for arbitrator appointments, with the trend toward greater representation continuing. Lex Arbitrate’s empanellment policy is being calibrated against the Equal Representation in Arbitration Pledge [VERIFY current text]. Third-party funding regulation continues to mature in Hong Kong and Singapore; counsel should verify the current TPF regime in any chosen seat [VERIFY all]. The institutional adoption of online hearings is now stable across leading institutions; the next frontier is AI-assisted procedural management. Lex Arbitrate’s institutional position is to permit AI-assisted procedural management with full transparency to the parties and the Tribunal, and to prohibit AI generation of substantive reasoning in awards.

Lex Arbitrate, in Q1 2026, completed the drafting of the Consolidated Rulebook v1.3 incorporating party-autonomy customisation (Article 2.2), tiered fee caps with completion incentive and delay disincentive (Article 5), evidence-bunching mandate (Article 24.2), continuous-sittings principle (Article 11.3), settlement-during-proceedings facilitation (Article 15), and online-by-default for Track I and Track II (Article 14.1). The v1.3 draft is awaiting formal Council adoption. The institution also drafted the Animation Discipline Addendum v1.2, launched the institutional Lexicon, and published this inaugural Quarterly Digest.
