Which issues did Sir William Blackstone mainly address as a member of Parliament?

As a member of Parliament, Sir William Blackstone was not a particularly zealous politician, describing himself as a man of moderation amidst the intense political conflicts of his time. During his nine years in the House of Commons, he primarily addressed legal and constitutional questions.1

The most notable instance of his parliamentary activity involved the Middlesex election of 1769. In this controversy, Blackstone supported the expulsion of the political reformer John Wilkes from the House of Commons. This stance drew significant criticism, as opponents argued his position was inconsistent with the legal principles he had previously outlined in his Commentaries on the laws of England.1
