Peirse returned himself on his long-established family interest at Northallerton all his adult life. Not a syllable is he known to have contributed to debate: nor was he to be nailed down in politics, though his general inclination, before 1790, was to be against the government. He voted with Pitt’s ministry on the Regency question, and was listed among opponents of the repeal of the Test Act in Scotland in 1791: indeed, he did not act with opposition until 30 May 1794, when he voted with Fox against the war with France. In the session of 1795 he was steady in opposition both to the war and to the suspension of civil liberty, as also to ministerial proposals for the payment of the Prince of Wales’s debts. The Treasury now listed him as ‘con’. He opposed repressive legislation in November 1795 and was in another minority on 15 Feb. 1796. He resumed this line in the session of 1796-7, voting for parliamentary reform on 26 May, as he had done in 1783 and 1785. He admitted to the Yorkshire reformer Christopher Wyvill that he was opposed to a county meeting for the dismissal of ministers at that time and, further, 6 Dec. 1798, that he was co-patron of an effectively closed borough
Peirse re-emerged in opposition on the resumption of war, 24 May 1803. He voted in the divisions of 15 Mar., 23 and 25 Apr. 1804 that contributed to Addington’s downfall. He was listed a Foxite throughout that year. He opposed Pitt’s additional force bill in June 1804, voting for its repeal, 6 Mar. 1805, as well as against the war with Spain, 12 Feb., and against ministers on defence, 21 Feb. He was in the opposition majorities against Melville, 8 Apr., 12 June 1805, and listed among them in July. His only known vote under the Grenville ministry was with them for the repeal of the Additional Force Act, 30 Apr. 1806, but he was listed among ‘staunch friends’ of the abolition of the slave trade and voted against the Portland ministry, 9 Apr. 1807.
Although his attendance remained somewhat unpredictable, Peirse justified the Whigs’ listing him as one of their adherents in 1810. He was present for most major divisions (except on 26 Jan. 1810)
Peirse was one of six Members who, according to Lord Duncannon, gave their ‘complete approval’ to Tierney’s leadership of opposition in the House, but who ‘object only to signing their names to anything, and who ... will never attend party meetings’.
He died 14 May 1824. He and his father between them represented Northallerton for 84 years.
