[Thomas Clark.] Autograph Letter Signed to Sir William Horne, threatening to 'Impeach Sir John Nicholl' over his 'Judgment in Dern & Clark'

3pp., 8vo. 72 lines. Bifolium. In good condition, on lightly aged and worn paper. Clark is writing again 'at the instigation of Friends', and hopes that 'in a Case of such vast public as well as private Importance, involving the Rights the Liberty & the Property of the Subject, you will extend to me your generous & powerful aid, at the Bar, or in the Senate'. His petition to the king (regarding 'Slotts Well'), certified by Horne, was suppressed, and he 'applied to Lord Eldon to present a Petition for me to the House of Peers'. Lord Eldon '(who well knows the Case & had declared that no body could more strongly than himself think it was an extremely hard one) condescended to speak to the Chancellor; & I felt encouraged to Petition the King, A fresh Petition was accordingly prepared, referring to the former one', and the Chancellor appointed a hearing of one counsel on each side. Clark continues to discuss the case, alleging evasion on the part of the opposite party. After quoting Blackstone he declares: 'Under the heaviest responsibility that man can lay himself I am prepared to Impeach Sir John Nicholl upon these grounds in his Judgment in Dern & Clark. I deiberately & fearlessly & not unadvisedly charge him with a Wilfully Partial & therefore Corrupt Decision.' An addition to the letter states 'That none of the Witnesses impugning the Well had any Communication with Testator for 12 months prior to its execution!!!'
