Error of Judgment lit a fire under the establishment when it was first published, shattering the prosecution case against six Irishmen charged with the Birmingham Bombings and going on to change the course of British legal history.

On the evening of 21st November 1974, bombs planted by the IRA in two crowded Birmingham pubs exploded, killing 21 people and injuring at least 170. Within a day of the explosion, six men - Paddy Hill, Gerry Hunter, Richard McIlkenny, Billy Power, Johnny Walker and Hughie Callaghan - were arrested and charged. All were found guilty.

Methodically, with total clarity and a tone that is both gripping and impassioned, then investigative journalist Mullin unpicked every detail of the case, revealing gaping holes in the prosecution case and the horrifying consequences of an establishment determined to close ranks.

Now 50 years on from the Birmingham Bombings and with new writing from Mullin, this classic edition of Error of Judgement tells the complete story of one of the most significant miscarriages of justice ever. As relevant now as it was when it was first published, it's an essential text on corruption, violence and bias in British policing and justice.
