A legal case in 1642 brought about the separation of the council of assistants into an upper house of the general court. The case involved a widow's lost pig and had been overturned by the general court, but the assistants voted as a body to veto the general court's act. The consequence of the ensuing debate was that the general court voted in 1644 that the council of assistants would sit and deliberate separately from the general court (they had sat together until then), and both bodies must concur for any legislation to be passed. Judicial appeals were to be decided by a joint session, since otherwise the assistants would be in the position to veto attempts to overturn their own decisions.
