Sch 10 para 6
(1) A person (“A”) is guilty of an offence if— (a) another person (“B”) commits the offence, and (b) B's commission of the offence is due to the act or default of A, and A is liable to be proceeded against and dealt with accordingly. (2) For this purpose it does not matter whether or not proceedings are taken against B. (3) A person (“A”) is guilty of an offence if— (a) A is a person other than the Crown, (b) the offence would have been committed by the Crown but for the fact that the provision under which the offence is committed does not bind the Crown, and (c) the Crown's commission of the offence would have been due to the act or default of A, and A is liable to be proceeded against and dealt with accordingly. (4) This paragraph is subject to any provision made in nuclear regulations.
