Coniston massacre
The board sat for 18 days in January 1929 to consider three incidents (Brooks, Morton and Tilmouth) that resulted in the deaths of Aboriginal people, and in one more day, finished its report, finding that 31 Aboriginal people had been killed and that in each case the death was justified.
Sir Henry Wilson, 1st Baronet
However, this claim has been challenged. Any order to assassinate Wilson would have had to have been relayed to them by Rory O'Connor (then in charge of British IRA operations) and the last assassination attempt contrived against Wilson had been set to be executed in 1921, not 1922. Coogan has suggested that Reginald Dunne, who had the confidence of both Michael Collins and Rory O'Connor, undertook the shooting as a last-ditch effort to provoke the British Government into retaliating, thereby uniting both sides of the Nationalists. Hart believes the assassins "acted alone in the (grossly mistaken) belief that Wilson was responsible for Catholic deaths in Belfast". The killers had only decided to attack the previous evening, and even on the day Sullivan had been at work until 1pm; the killers had no getaway plan.
