In 1750 Blackstone was a prominent Oxford Tory, and took the lead in proposing Sir Roger Newdigate as candidate for the university and in carrying his election in January 1751;
My temper, constitution, inclinations, and a thing called principle, have long quarrelled with active life ... and have assured me I am not made to rise in it. Besides there are certain qualifications for being a public speaker, in which I am very sensible of my own deficiency; and happy that I am sensible so early.
But his Oxford lectures brought him back to an active life. Lord Fitzmaurice gave a ‘book’ of them to Bute for the Prince of Wales, and further copies were sent direct;
Blackstone is a man of business, and may be more so, and perhaps more useful. He is guardian or deeply connected with Ld. Suffolk and Ld. Abingdon, and may draw a certain part of that connexion with him. Such I take his merits to be, besides what your Lordship knows already of him.
Blackstone at first declined the offer;
In the House Blackstone was an infrequent and ‘an indifferent speaker’:
Journals 1623, House resolved our fishermen ought to have right to fish in New England and to take necessary wood and timber—a strong mark of superiority ... any infringement upon the natural rights for mankind the same as taxing—exertion of power over property—if you have one you have the other. Penalty upon persons in New England cutting down trees under 5 inch—penalties are the same as taxes—no difference between a law with a pecuniary penalty and a tax. The Stamp Act is only a law with a penalty.
On 22 Feb. Blackstone voted against the repeal; and on the 24th moved a clause that the repeal should apply to those colonies only ‘who expunge out of their Assembly the resolutions ... derogatory from the honour and dignity of the Crown and Parliament’.
In 1768 Blackstone was returned for Westbury on Lord Abingdon’s interest. In the new Parliament most of his speeches—and between November 1768 and January 1770 he intervened in 11 debates—were on Wilkes. On 1 Feb. 1769 he made the motion which condemned Wilkes’s petition indicting Mansfield.
I must give my reasons for voting against gentlemen, with whom I have usually voted, and may hereafter vote. You have information more than enough to cast the severest censure upon that unhappy man. This paper is not the cause of the public, but the cause of the minister.
On 3 Feb. however, he spoke and voted for Wilkes’s expulsion because of the ‘Essay on Woman’:
When I see all religion made a mockery and jest of, it behoves me to vindicate my God and my King.
On 8 May 1769 Blackstone gave it as his ‘firm and unbiassed opinion’ that Wilkes was disqualified by common law from sitting in the House, for ‘the law and custom of Parliament is part of the common law’; and the House of Commons, with regard to its own privileges and Members, can declare law without appeal or review.
When on 31 Jan. 1770 Dowdeswell moved that no person eligible by law can be incapacitated by a vote or resolution of the House, but by Act of Parliament only, Blackstone is reported to have said:
As to the question whether expulsion does of itself imply incapacity, I have never answered it in the affirmative, neither have I ever declared the contrary. I did not vote in the question last year, and I shall not, by any vote that I may now give, be included in that question.
This was Blackstone’s last recorded speech in the House. On 9 Feb. his appointment to the Bench vacated his seat.
He died 14 Feb. 1780.
