Nicholl, an advocate at Doctors’ Commons, succeeded another eminent civilian Sir William Scott as an official of the London and Middlesex archdeaconries in 1788.
Nicholl had no intention of exceeding his professional brief in Parliament, though he joined the ministerialists invited to hear the King’s speech in advance, 21 Nov. 1803. He transferred his allegiance to Pitt in 1804 and adhered to him on Melville’s case, 8 Apr. 1805. In his first major speech, 11 Feb. 1805, he justified war against Spain in terms of international law and on 25 May justified the prize agency bill. On Pitt’s death he was ready to resign unless granted freedom of parliamentary conduct. The Grenville ministry did not discharge him: they required his services to regulate relations with the United States.
Nicholl was enlisted by their successors, who gave him the option of a seat for Rye and kept him busy. Henceforward, however, he sat for Bedwyn on the 1st Earl of Ailesbury’s interest, recommended by Spencer Perceval. He justified the King’s freedom of action with regard to the droits of Admiralty, 11 Feb. 1808, defended the orders in council, 18 Feb., denying that they would lead to rupture with the United States, justified commercial licences, 7 Mar., and gave the official view of the case of Sir Home Popham, 31 May. He resigned as King’s advocate in January 1809 to succeed Sir William Wynne as dean of the arches; but the Duke of Portland secured his admission to the Privy Council to assist in prize and plantation cases.
Nicholl’s change of office in 1809 was also followed by increasing political commitment. He had not been ‘much either of a politician or a party man, except being an enthusiastic admirer of Mr Pitt’. In 1807, when Charles Abbot asked him to second his re-election to the Speaker’s chair, he had declined: ‘I have always confined myself to matters immediately connected with my profession upon which alone I can hope to be entitled to any attention’.
If Nicholl had been answered by Whitbread or any Cath[olic] as violent as he (Nich[oll]) was a Protestant—the debate would have been a conflict of outreageous extravagences on both sides—which would have been to Per[ceval] gagne de cause. This I completely spolied. I annihilated Nicholl’s speech (which was in fact every syllable of it P[erceval]’s own sense and sentiment)—but did so in perfect good humour and with perfect civility to Nicholl, and left on the dicussion a tone and impression of moderation, which is what of all things what P[erceval] has the most to dread.
This was confirmed by Francis Horner, who reported that Hicholl was ’stiffled by Canning’:
it is very amusing that Sir John Nicholl should have maintained on this occasion the character of the faculty to which he belongs: for all through the parliamentary history it appears that exploded prejudices and abuses of every sort find their last advocates among the civilians of Doctors Commons ... They come from their monastry in St. Paul’s churchyard with opinions which all the rest of the world would have rejected, or begin to be ashamed of.
He was not in fact a bigot and, as a member of the committee of the National Society for Anglican Schools, threatened to resign from it that year if a doctrinaire curriculum was imposed on them.
Nicholl appeared as a Treasury supporter after the election of 1812 and, at Castlereagh’s request, proposed Charles Abbot’s re-election as Speaker, 24 Nov. On 24 May 1813 he was again a leading opponent of Catholic relief. He got out of a scrape at this time, connected with his wish for an independent seat in the House. In April 1812his name had been mentioned for the representation of his university, but he had before this negotiated the purchase of (Sir) Mark Wood I’s interest at Shaftesbury for £50,000 and wriggled out of it on discovering that it was a doubtful asset, likely to blemish his reputation. Nicholl’s nephew Robert Peter Dyneley then paid a deposit on the purchase, but did not complete it. In 1813 Wood threatened to publicize the matter and it was the Speaker who reluctantly agreed to arbitrate between the parties and awarded against Wood, 14 July 1813.
More to Nicholl’s liking would have been a seat for Glamorgan. He had purchased the Merthyr Mawr estate in 1804 and rebuilt the residence and had founded a national school at Bridgend in 1812, following this up in 1817 with a savings bank. Yet the vacancy of 1814 did not tempt him and he was content subsequently to play an important part in deceiding elections. He had also ruled out Oxford Univeristy when again solicited that year.
