He was admitted to
Lincoln's Inn on 11 July 1621. In 1628 he served as a
barrister, and he was appointed
Recorder of Dublin. Other appointments included
Prime Sergeant, 6 October 1629. He was admitted to
King's Inn, 15 April 1630, (he served twice as its treasurer) and was
Member of Parliament for
Lismore in 1634. He became second Baron of the
Court of Exchequer (Ireland), 5 August 1634, through the influence of
Lord Wentworth. He published in 1637, at the request of Lord Wentworth, to whom he dedicated it,
The Case of Tenures upon the Commission of Defective Titles, argued by all the Judges of Ireland, with the Resolution and the Reasons of their Resolution, a crucial test case from the Crown's point of view. In 1640 he used what influence he had, but in vain, with
Sir James Ware and other members of the
Irish House of Commons, to prevent their sending a committee of their body to England to
impeach the
Earl of Strafford, as Wentworth now was. History says nothing of his life for the next twenty years. He was chairman of the Royalist Convention, 7 July 1659. This met at Dublin in defiance of the government. It voted for the unconditional
Restoration of Charles II. In November 1660, "in consideration of his many good services to
Charles I and his eminent loyalty to
Charles II", he became
Lord Chief Justice of the King's Bench for Ireland, and
Privy Counsellor. He was appointed a commissioner to execute the King's Declaration which ultimately led to the
Act of Settlement 1662. He was accused, rather obscurely, of being "a cold friend" to the Declaration, and this, as well as his increasing infirmity, was one of the "material objections" which led to his being rejected as Speaker of the
Irish House of Lords. However, he did sit on the Lords Committee to consider the state of the Irish
coinage. As Treasurer and Council member of the King's Inns he was accused of being dilatory and inefficient, perhaps as a result of the "infirmity" referred to above. ==Ennoblement==
