The convictions of the Guildford Four are quashed by the Court of Appeal of England and Wales, after they had spent 15 years in prison.
The Guildford Four and Maguire Seven were the collective names of two groups whose convictions in English courts in 1975 and 1976 for the Guildford pub bombings of 5 October 1974 were eventually quashed after long campaigns for justice. The Guildford Four were wrongly convicted of bombings carried out by the Provisional Irish Republican Army (IRA); the Maguire Seven were wrongly convicted of handling explosives found during the investigation into the bombings. Both groups' convictions were eventually declared "unsafe and unsatisfactory" and reversed in 1989 and 1991 respectively after they had served up to 15–16 years in prison. Along with the Maguires and the Guildford Four, a number of other people faced charges relating to the bombings, six of them charged with murder, but these charges were dropped. No one else was charged with the bombings, or supplying the material; three police officers were charged with conspiracy to pervert the course of justice, but found not guilty.
