He had also sent letters to his sister in 1880, Caroline Maclean, stating that, "If I cannot commit a murder one way, I will another way, and all can add is, if there is more difficulty, there may be more victims." Multiple doctors also testified that Maclean was insane and "did not believe he was capable of appreciating the nature or quality of any act which he might commit." Tried for high treason on 20 April, Maclean was found "not guilty, but insane" by a jury after five minutes' deliberation, overseen by Lord Chief Justice Coleridge. and he lived out his remaining days in Broadmoor Asylum. The verdict prompted the Queen to ask for a change in English law so that those implicated in cases with similar outcomes would be considered as "guilty, but insane"; this led to the Trial of Lunatics Act 1883. A poem was later written about Maclean's attempt on the Queen's life by William Topaz McGonagall.
