Jonathan Ernest Pim PC (1858–1949), was an Irish lawyer and judge, and Liberal politician.
His grandfather, also called Jonathan Pim, served as an MP for Dublin City between 1865 and 1874.
After the Easter Rising of 1916 he was briefly appointed a Lord Justice of Ireland, charged with emergency powers of government.
After the establishment of the Irish Free State, like nearly all the pre-independence judges he was required to retire under the Courts of Justice Act 1924.
[1] Maurice Healy in his memoir The Old Munster Circuit suggests that Pim's retirement probably came as a relief to him, since despite his great charm, courtesy and erudition he was not a lawyer of adequate calibre for any of the offices he filled, and he had not expected to be appointed to any more senior office than a county court judge.
