The descendant of Huguenots on his French-born father’s side, and of ‘a very respectable’ Irish family on his mother’s, Perrin was born at Waterford in 1782. Being one of a large family, Perrin’s future was only assured after his father, an author, teacher of French, and supporter of nationalist ideals, inherited a large fortune amassed in the French East Indies by his brother. The family then resided in Ulster, and Perrin attended the Diocesan School of Armagh. Having been ‘more a plodding than brilliant student’, he gained a scholarship at Trinity College, Dublin, where ‘he was distinguished among his associates as an uncompromising reformer’.
After being called to the Irish bar in 1806, Perrin swiftly became versed in criminal and, more particularly, mercantile law. Having fallen under the tutelage of Robert Holmes, he acted as junior counsel in a number of prominent cases, before leading the defence of Daniel O’Connell at his state prosecution early in 1831.
Having been spoken of as a candidate for Dublin city in 1830, Perrin was returned for that constituency as a reformer at the general election of 1831, but was unseated on petition, 8 Aug. 1831.
As parliament assembled, it was rumoured that Perrin would become Irish attorney-general, and he therefore proved reluctant to oppose the ministry.
During 1833-4, Perrin served on select committees on the Dublin and Kingston ship canal, civil list charges, the admiralty court, chancery officers, and medical charities.
When the Whig ministry was dismissed in November 1834, Perrin refused to join O’Connell’s Anti-Tory Alliance, an organisation which he feared was unconstitutional. Along with Michael O’Loghlen, he made an unsuccessful attempt to establish an independent Liberal organisation in Dublin, free from O’Connell’s dictation.
As chief law officer, he strove for impartiality, tempered by sympathy for the position of Catholics, in the administration of the law.
Perhaps his most significant political contribution was the ‘yeoman service’ he rendered in supervising the inquiry into Irish municipal corporations. The commission’s work was regarded as ‘a monument of research’ which amply illustrated ‘the ancient municipal history of Ireland’. In spite of ‘agonies of rage’ from the Conservative benches after Perrin was appointed chief commissioner in July 1833, he ably coordinated the work of the commission from Dublin.
Perrin was now regarded as the champion of Irish reform, and made an effective speech in support of Lord John Russell’s resolution to engraft appropriation to the Irish tithe bill.
Perrin’s elevation to the bench was hailed in Liberal circles as ‘a benefit to Ireland of the first order’.
In poor health, Perrin resigned his seat on Queen’s Bench in February 1860 (yet continued to dispense justice at petty sessions in county Dublin), the death of his eldest son, John, the assistant-barrister for county Louth and counsel to the Irish government, being held as the reason for his abandonment of public life.
