Tuckiar v The King is a landmark Australian judgment of the High Court which was decided on 8 November 1934, after a two-day hearing on 29–30 October 1934. The matter examined the behaviour of the judge and lawyers in the trial of Yolngu man Dhakiyarr (Tuckiar) Wirrpanda in the Northern Territory Supreme Court a year earlier for one of the Caledon Bay murders, and overturned the judgement which had found the appellant guilty and sentenced him to death.
