Congress was to be similar to the Continental Congresses, with one chamber representing states, with a quorum of state delegations. Each state could fill Provisional Congressional vacancies as it wished. Although not mandatory, the President might appoint cabinet members from Congress. In an effort at government economy, the president was authorized to veto individual items from appropriation bills. The Provisional Constitution organized each state into a federal judicial district — this provision was adopted in the permanent Confederate Constitution, but, in the only amendment to either document, this provision was amended to allow Congress to determine federal districts on May 21, 1861. A supreme court was to be constituted by convening all the federal district judges. To continue judicial procedure in the Confederacy as it had been in the United States, judicial power was extended to all cases of law and equity arising under the laws of the United States. From February 28 until March 11, 1861, the Provisional Congress resolved itself into a Constitutional Convention each day, and, as a convention, it adopted the Permanent Confederate Constitution unanimously. On March 12, Howell Cobb of Georgia, as president of the Constitutional Convention, forwarded it to the state secessionist conventions. Several Congressmen returned to their home states to lobby for adoption, and all conventions ratified without submitting the new Constitution to a referendum by the people. The permanent Constitution, like the provisional one before it, was primarily modeled on the U.S. Constitution, modified by the Convention's desire to write a Southern constitution. The national government was clearly to be only an agent of the states, powers to the central government were “delegated” not “granted”. It provided for a bicameral national legislature consisting of a House of Representatives and a Senate. The rights and duties of Congress received the most attention, most importantly related to fiscal matters such as export duties, discouraging internal improvements but for navigational aids, and the self-sustaining post office. To limit log-rolling, a two-thirds vote in each house was required for appropriations bills not recommended by an executive department, and the president had line-item-veto power. In Article III, radical states' righters struck the provisional Constitution's provision extending federal jurisdiction over cases between citizens of different states. Additionally, federal judicial power no longer applied to all cases of law and equity to accommodate the Roman law concept of single jurisdiction in Louisiana and Texas. Congressional apportionment remained on the
