Doherty was made a King's Counsel in 1823 (becoming a Queen's Counsel with the accession of Queen Victoria to the Throne in 1837). He was Member of Parliament for New Ross, Kilkenny City and Newport (Cornwall) and served as Solicitor-General for Ireland from 1827 to 1830. He was a Bencher of the King's Inns. In 1830 he was appointed Chief Justice of the Irish Common Pleas, in which office he remained until his death from heart disease in 1850. As a judge, he was described as courteous and painstaking, but not deeply learned.
