Last week, following a three-month trial, Mr Justice Henshaw handed down judgment in Alta Trading UK (formerly known as Arcadia Petroleum Limited) v. Bosworth [2025] EWHC 91 (Comm).

The case was heard in the Commercial Court from May to July 2024.

The Judgment summarises the law relating to dishonesty, unlawful means conspiracy, breach of fiduciary duty, dishonest assistance and knowing receipt, as well as some issues of Swiss law.
