Thomas Slaney Poole (3 July 1873 - 2 May 1927), commonly referred to as "Justice Poole" was a South Australian lawyer.
Poole was born in Strathalbyn, South Australia, the eldest son of Frederic Slaney Poole "Canon Poole" (9 July 1845 - 28 June 1936) and Rebecca Poole, née Scott (c. 1843 - 10 May 1931). He attended St. Peter's College, where he had a distinguished scholastic career. He entered Trinity College, University of Melbourne, graduating BA with first class honours in Greek, Latin and comparative philology in 1894.
In December 1894 Professor E. V. Boulger (1846-1910) resigned his position as Professor of Classics and Comparative Philology and Literature at the University of Adelaide. Poole was appointed to take over his Classics lectures for the months of March to May 1895.
He returned to Melbourne, where he graduated MA in 1896 and LLB (with honours) in 1897. He was called to the Victorian Bar the same year. He then became associate to Justice Bundey in Adelaide, then entered a partnership with Percy Emerson Johnstone (c. 1875-1951) from around 1910 to 1919. Despite Poole's notorious misogyny, Mary Kitson was articled to this partnership, which later became Johnstone, Ronald and Kitson. Poole took silk in 1919 and was appointed fourth judge of the Supreme Court of South Australia on 25 September that same year.Arthur William Piper succeeded him on the bench on 16 June 1927.
Poole acted as Administrator (or Lieutenant Governor) of South Australia from 9 April 1925 to the end of November while the Governor, Sir Tom Bridges and the Chief Justice Sir George Murray were absent from the State.
