Handling a salmon in suspicious circumstances
Handling a salmon in suspicious circumstances sounds like it may be an archaic law, but it is in fact enshrined in Section 32 of the Salmon Act 1986.
It is aimed at selling fish gained through illicit means - rather than people furtively skulking around dark corners clutching their Salmo salar. The phrasing is broad enough to provoke thought, however.
A five-hour House of Lords debate about the issue in February 1986 decided the wording would protect unwitting people from the then-in-place wider law of "possessing salmon which have been illegally taken, killed or landed".
