Chandler v DPP [1964] AC 763 (HL) FACTS: The appellants had wished to demonstrate their opposition to nuclear weapons. They had planned a non-violent action to immobilise an aircraft at an RAF station for a period of six hours. They were convicted of conspiracy to commit a breach of the Official Secrets Act 1911, s 1, namely to enter a prohibited place for 'a purpose prejudicial to the safety or interests of the state'. HELD: On appeal against conviction, Radcliffe LJ agreed with the trial judge's direction to the jury that the appellants had made their entry for two separate purposes:

'… an immediate purpose of obstructing the airfield, and a further or long-term purpose of inducing or compelling the government to abandon nuclear weapons in the true interests of the state.'

Where the jury were satisfied that the appellant's immediate purpose was proven, they were right to find the appellants guilty, regardless of whether they thought the long-term purpose in itself beneficial. Their motive behind the immediate action was irrelevant, they still intended the method of achieving it.
