Fitzgerald rose from relatively modest circumstances to a position of considerable eminence in Irish political and legal circles. When first appointed to legal office he had gained a reputation as a first-rate lawyer and a ‘bold and confident’ debater, a reputation that survived his dismissal by the Duke of Portland in 1782 and lasted until the Union. His politics were for moderate reform and Catholic relief within the framework of an independent Irish legislature. He therefore fiercely opposed the Union and thereby forfeited office.
Having thus demonstrated that he would not ‘bend’ his conscience ‘to personal views’, he was prepared, as Member for Ennis on his own interest in the Imperial Parliament, to accept the Union and support Addington’s government: though in explaining his absence from Parliament, 10 Feb. 1803, by reference to chancery and assize business, he assured the chief secretary that the premier knew of his inclination ‘by accident and not by any design on my part’. Confident that his having differed once from ministers on principle need not tell against him, he applied to government to satisfy his ambition to be a judge. On 28 May 1803 he asked if he might succeed Lord Avonmore as master of the rolls and on 25 July he suggested that he should succeed Lord Kilwarden as chief justice of the King’s bench, having acted with him ‘for fifteen years in every legal and parliamentary difficulty in which the government of this country was engaged’. He assured Hardwicke:
I availed myself of the first opportunity to show that displaced, I was as ready to support the King’s government, as when I held that which in my hands was the most lucrative office in my profession. Mr Wickham knows that I did not stand aloof, or wait for events; that in the untried state of the administration I avowed myself an unequivocal friend; that whenever occasion offered, I gave my humble aid to those measures which are immediately dependent on your excellency.

He had in fact first spoken at Westminster in favour of the extension to Ireland of the lunatic property bill, 21 Apr. 1803, instancing it as a case for the assimilation of English and Irish law. On 4 and 11 May he also defended the Irish law courts bill, provided it compensated those who lost office, and moved the extension to Ireland of the bill for preventing improper arrests.
Fitzgerald was unable to reconcile his willingness to support Irish administration with adherence to Pitt’s second ministry in 1804, although ministers thought they could manage him by reference to his role as ‘prime minister’ to Chief Secretary Nepean and his ambitions for himself and his son William. As early as February 1804 he was in a list of Irish Members set in motion by the Prince of Wales, and on 10 June the lord lieutenant was informed that Fitzgerald had thrown in his lot with the Prince. In January 1805 he was promising the Prince a statement of the different interests in Ireland.
By 1806 Fitzgerald’s political energies were probably spent. He supported the Grenville ministry, which enabled him to move for an Irish census. They realized that he still wanted a place for himself or his son. At the outset of their ministry, he had got the Prince to apply to Fox for him to succeed Sir Michael Smith as master of the rolls in Ireland. Curran was in fact appointed, and nothing came of the lord lieutenant’s suggestion that Fitzgerald should be attorney-general. He himself refused to countenance the revival of the prime serjeant’s office in his favour and thought it infra dig. to succeed the disgraced judge Robert Johnston at the common pleas.
In 1812, when William contested county Clare, Fitzgerald was again returned for Ennis, but surrendered the seat to his son on his failure to capture the county seat. In 1815 William applied for a peerage for his father, but as his own political services were the basis for the claim and as the viceroy had reservations about ‘the old gentleman’s private character’, it was rejected.
