Cases considering section 342 10

The National Crime Agency v N & Anor (Rev 1)

[2017] EWCA Civ 253 · 7 April 2017Limits

The section’s prohibition on disclosures likely to prejudice an investigation constrained the bank’s evidence and made firm interim findings about its suspicion or the property’s status inappropriate. (see paras [24]; [63]; [76])

Serious Organised Crime Agency v Perry & Ors

[2010] EWCA Civ 907 · 29 July 2010Limits

Section 342 creates offences involving disclosure likely to prejudice an investigation and falsification, destruction or disposal of relevant documents. The majority treated criminal sanctions as a factor against unrestricted extra-territoriality. (see paras [16]; [40])

The Wine Enterprise Investment Scheme Limited (In Liquidation) v Crowe UK LLP

[2026] EWHC 692 (Ch) · 27 March 2026Limits

Limits disclosure that might prejudice a money-laundering, confiscation or civil-recovery investigation. The possibility of liability under this provision supported the conclusion that a resignation statement would need to be terse. (see paras [411]-[419], [574]-[576])
