Necessary and Proper Clause in the context of Enumerated powers (United States)

Article One of the Constitution of the United States establishes the legislative branch of the federal government, the United States Congress. Under Article One, Congress is a bicameral legislature consisting of the House of Representatives and the Senate. Article One grants Congress enumerated powers and the ability to pass laws "necessary and proper" to carry out those powers. Article One also establishes the procedures for passing a bill and places limits on the powers of Congress and the states from abusing their powers.

Article One's Vesting Clause grants all federal legislative power to Congress and establishes that Congress consists of the House of Representatives and the Senate. In combination with the vesting clauses of Article Two and Article Three, the Vesting Clause of Article One establishes the separation of powers among the three branches of the federal government. Section 2 of Article One addresses the House of Representatives, establishing that members of the House are elected every two years, with congressional seats apportioned to the states on the basis of population. Section 2 includes rules for the House of Representatives, including a provision stating that individuals qualified to vote in elections for the largest chamber of their state's legislature have the right to vote in elections for the House of Representatives. Section 3 addresses the Senate, establishing that the Senate consists of two senators from each state, with each senator serving a six-year term. Section 3 originally required that the state legislatures elect the members of the Senate, but the Seventeenth Amendment, ratified in 1913, provides for the direct election of senators. Section 3 lays out other rules for the Senate, including a provision that establishes the vice president of the United States as the president of the Senate.

McCulloch v. Maryland, 17 U.S. (4 Wheat.) 316 (1819), was a landmark U.S. Supreme Court decision that defined the scope of the U.S. Congress's legislative power and how it relates to the powers of American state legislatures. The dispute in McCulloch involved the legality of the national bank and a tax that the state of Maryland imposed on it. In its ruling, the Supreme Court established firstly that the "Necessary and Proper" Clause of the U.S. Constitution gives the U.S. federal government certain implied powers necessary and proper for the exercise of the powers enumerated explicitly in the Constitution, and secondly that the American federal government is supreme over the states, and so states' ability to interfere with the federal government is restricted. Since the legislature has the authority to tax and spend, the court held that it therefore has authority to establish a national bank, as being "necessary and proper" to that end.

The state of Maryland had attempted to impede an operation by the Second Bank of the United States through a tax on all notes of banks not chartered in Maryland. Though the law, by its language, was generally applicable to all banks not chartered in Maryland, the Second Bank of the United States was the only out-of-state bank then existing in Maryland, and the law was thus recognized in the court's opinion as having specifically targeted the Bank of the United States. The Court invoked the Necessary and Proper Clause of the Constitution, which allows the federal government to pass laws not expressly provided for in the Constitution's list of enumerated powers of Congress if such laws are necessary and proper to further the powers expressly authorized.

The Commerce Clause describes an enumerated power listed in the United States Constitution (Article I, Section 8, Clause 3). The clause states that the United States Congress shall have power "to regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes". Courts and commentators have tended to discuss each of these three areas of commerce as a separate power granted to Congress. It is common to see the individual components of the Commerce Clause referred to under specific terms: the Foreign Commerce Clause, the Interstate Commerce Clause, and the Indian Commerce Clause.

Dispute exists within the courts as to the range of powers granted to Congress by the Commerce Clause. As noted below, it is often paired with the Necessary and Proper Clause, and the combination used to take a more broad, expansive perspective of these powers.

The Constitution of the State of Texas is the document that establishes the structure and function of the government of the U.S. state of Texas and enumerates the basic rights of its citizens. The current document was adopted on February 15, 1876, and is the seventh constitution in Texas history (including the Mexican constitution of 1872). The previous six were adopted in 1827 (while Texas was still part of Mexico and half of the state of Coahuila y Tejas), 1836 (the Constitution of the Republic of Texas), 1845 (upon admission to the United States), 1861 (at the beginning of the American Civil War), 1866 (at the end of the American Civil War), and 1869. Texas constitutional conventions took place in 1861, 1866, 1868–69, and 1875.

The constitution is the second-longest state constitution in the United States (exceeded only by the Constitution of Alabama) and is also the third-most amended state constitution (only the Alabama and California constitutions have been amended more often). From 1876 to 2024 (following the 88th Legislature), the Texas Legislature proposed 714 constitutional amendments. Of that total, 530 were approved by the electorate, 181 were defeated, and 3 never made it on the ballot. Most of the amendments are due to the document's highly restrictive nature: the constitution stipulates that the state of Texas has only those powers explicitly granted to it; there is no counterpart of the federal Necessary and Proper Clause.
