He will replace the current Deputy Bailiff, Tim Le Cocq, who is due to become Bailiff following the retirement of Sir William Bailhache.
Mr MacRae, who was educated at La Moye School, Victoria College prep and Victoria College, attended the University of Exeter before being called to the English Bar in 1990.
He practised as a barrister on the Western Circuit, principally defending and prosecuting criminal cases in crown courts.
He returned to the Island in 2001 and passed the Jersey Bar exams in 2002. He joined Carey Olsen as a partner in 2005, specialising in trust litigation.
Mr MacRae was appointed a Crown Advocate in 2008 and Attorney General in May 2015.
‘It is an honour to have the opportunity to serve the Island as Deputy Bailiff. Jersey has been well served over a long period by a strong, independent judiciary and I will endeavour to uphold the high standards set by my predecessors.
‘Jersey’s criminal justice system is soon to undergo significant changes as a consequence of reforms to criminal procedure enacted by the States last year, and I look forward to contributing to the implementation of these changes,’ he said.
