Martin left the Exchequer bench in 1873, due to deafness, and was appointed a
Privy Counsellor on 2 February 1874. He returned to the
Middle Temple in 1878. He divided his time between his estate at Myroe, County Londonderry (where he was a
justice of the peace and a
deputy lieutenant) and his London residence in
Piccadilly. He died at the latter in 1883 and is buried in
Brompton Cemetery, London. ==Arms==
