Disclosure in Complex Fraud Trials: A Practical Guide

Why the disclosure exercise often decides the outcome, and how to approach it from the first day of instruction.

In a document-heavy fraud case, the prosecution’s duty of disclosure is where cases are won and lost. Millions of pages cannot be reviewed by hand, and the way a team chooses to search them shapes the entire defence.

Define the issues before the search

Disclosure reviews that begin with keywords alone produce volume, not insight. A short, written statement of the issues in the case, agreed with the client and updated as the case develops, gives the review a spine.

Challenge the prosecution’s approach

The defence is entitled to question how material was gathered, how it was searched and why items were treated as unused. Targeted, reasoned requests carry far more weight than blanket complaints.

Keep the client close

Clients know their business and their colleagues. Their help in identifying the documents that matter is invaluable, and it keeps the defence anchored in the facts rather than in procedure alone.
