Samuel Blatchford, Ames v. Quimby (106 U.S. 342)…
“ He was then asked, 'When was that contract signed?' The defendants objected to the question on the ground that 'it was irrelevant and immaterial, and there had been no previous denial by affidavit or otherwise of the execution of the contract, and it was incompetent.' The plaintiff replied that the fact of the execution of the contract was not denied, 'but he proposes to show the time of the execution of the contract was on Sunday, which avoids the contract.' The court overruled the objection, and the defendants excepted. ”
