The court discussed the need to assume that conviction for an offence required proof of mens rea.
Lord Goddard CJ said: ‘It should first be observed that at common law there must always be mens rea to constitute a crime; if a person can show that he acted without mens rea that is a defence to a criminal prosecution. There are statutes and regulations in which Parliament has seen fit to create offences and make people responsible before criminal Courts although there is an absence of mens rea, but it is certainly not the Court’s duty to be acute to find that mens rea is not a constituent part of the crime. It is of the utmost importance for the protection of the liberty of the subject that a Court should always bear in mind that unless a statute, either clearly or by necessary implication, rules out mens rea as a constituent part of a crime, the Court should not find a man guilty of an offence against the criminal law unless he has a guilty mind.’
