Since the original gag was a resolution, not a standing House Rule, it had to be renewed every session, and the Adams' faction often gained the floor before the gag could be imposed. However, in January 1840, the House of Representatives passed the Twenty-first Rule, which prohibited even the reception of anti-slavery petitions and was a standing House rule. Now the pro-petition forces focused on trying to revoke a standing rule. The Rule raised serious doubts about its constitutionality and had less support than the original Pinckney gag, passing only by 114 to 108. Throughout the gag period, Adams' "superior talent in using and abusing parliamentary rules" and skill in baiting his enemies into making mistakes, enabled him to evade the rule and debate the slavery issues. The gag rule was finally rescinded on December 3, 1844, by a strongly sectional vote of 108 to 80, all the Northern and four Southern Whigs voting for repeal, along with 55 of the 71 Northern Democrats.
