EXPERT SERVICES

J TUDOR CONSULTING provides independent expert evidence, litigation support and dispute consulting to law firms and specialist houses in the United Kingdom, Hong Kong and internationally. Instructions are accepted only where independence can be maintained and the subject matter sits inside Jason’s first-hand experience. He is available to be instructed as a sole expert, a shadow expert, or as a specialist contributor to a larger expert team. He is accustomed to working to the standard expected of CPR Part 35 and the equivalent regimes in Hong Kong and other common-law seats.

 

Subject matter expertise:

​

  • Physical and financial commodity markets — metals, energy and softs — including warehouse, inventory, offtake, financing and hedging structures as well as listed and OTC derivatives.

  • Structured products, notes, commodity hybrids, indices and exchange-traded products, including issuance, hedging, capacity, marketing and the duties owed to professional and private clients.

  • Market practice in sales and trading: order handling, pre-hedging, voice and electronic execution, last-look and fixings, position limits, and the use of related-party or intra-group liquidity.

  • Wash trades, circular trading, layering, spoofing and other forms of alleged market abuse or artificial volume.

  • Pricing, marking, model use and reserve methodology — and the difference between an honest mark and an indefensible one.

  • Electronic and algorithmic trading failures, control gaps around automated order flow, and the allocation of responsibility between trader, desk, platform and control functions.

  • Trade-lifecycle and operational failure: confirmation breaks, settlement delay, failed bookings, margin and clearing disputes, and the consequences of inadequate automation.

  • Trade-finance structures and alleged fraud in commodity and structured-finance flows.

  • Client onboarding, KYC, suitability and appropriateness, and the duty to treat customers fairly.

  • Information barriers, MNPI, Chinese walls and the misuse of confidential client information.

  • The design and operation of risk, compliance and audit frameworks, including whether a reasonably competent institution in the relevant market and year would have detected, escalated or stopped the conduct complained of.

  • Senior-manager accountability, escalation matrices, internal investigations and the standard of care expected of heads of business, risk, audit and operations.

  • Post-merger integration and book migration: whether the planning, resourcing and execution of a combination — people, positions, platforms, licences and client assets — met the standard of a competent global bank.

  • The market and operational context of institutional distress, including administration, close-out, porting of positions and the duties of a regulated firm in a collapsing counterparty.

​

  • Assistance with disclosure strategy, witness preparation and the testing of opposing expert evidence.

  • Hot-tubbing and oral evidence in court, arbitration or before regulators.
