“Acting as an officer of one company, a person may dishonestly procure or assist a breach of duty by the director of another company, in which case such person may make liable for dishonest assistance both himself personally and the company of which he is an officer. Otherwise, individuals acting as officers of a company could never commit any wrong, tortious or equitable. What matters in the present context are, in short, the factual questions whether the respondents procured or assisted Mr Taylor’s breaches of duty, what knowledge they had when giving such assistance, and whether any honest person(s) in their position giving such assistance with that knowledge could have believed that the relevant transaction was in IAMF’s interests.”
