James Clarke, Attorney-General of the Isle of Man in the years after Waterloo.

He held the office from about 1816, and it is his opinion that later writers cite on a point of Manx usage: that the presiding officer of the House of Keys was properly the Chairman rather than the Speaker.

He worked largely by post, and often from the mainland. The Home Office papers have him writing from Liverpool about the behaviour of the water bailiff, from Lancaster about a proposed interview with Lord Sidmouth and his own travel to the Island, and on the rank and precedence of the Attorney-General and the state of the laws. His absences and the difficulty of filling the office in his room are a recurring theme: a warrant was issued for J. C. Gelling to act as Attorney-General and then returned unused, and correspondents were pressing the merits of J. J. Heywood for the place.

The Duke of Atholl used him as a legal referee. In January 1823 the Duke put to him a set of questions on the role of the Keys in the Court of General Gaol Delivery, and whether they had a voice in the court giving judgement. Clarke found them difficult to answer and advised that the whole matter be put to the Home Secretary instead. He gave a guarded reply to Thomas Fell's petition and complaint against Deemster Gawne, and in March 1823 he was arguing that an English barrister was needed to fill the office of First Deemster.
