R v McPhillips [1990] 6 BNIL (NICA)
FACTS: D had joined in a conspiracy to plant a bomb, timed to explode on the roof of a hall at 1am when a disco would be at its height. He claimed that, unknown to his accomplices, he intended to give a warning enabling the hall to be cleared.
HELD: The Court of Appeal of Northern Ireland held per Lowry LJ:

'In regard to the offence of statutory conspiracy s 1(1) assumes the existence of an intention of the parties to carry out the agreement. But on the facts found here, this result [murder] would not have been in accordance with the intention of the appellant. Therefore he was not guilty of conspiracy to murder.'
