Interstate compact

In the United States, an interstate compact is a pact or agreement between two or more states, or between states and any foreign sub-national government.

Description

Most early interstate compacts resolved boundary disputes, but since the early 20th century, compacts have increasingly been used as a tool of state cooperation and mutual recognition on infrastructure, services and professional licensing, often to ease administrative barriers and reduce costs and litigation. In some cases, an agreement will create a new multi-state governmental agency which is responsible for administering or improving some shared resource such as a seaport or public transportation infrastructure. Compacts may also be limited to a certain multi-state region, may be open to all states and insular areas, or may be open to subnational governments in other countries.

Interstate compacts are distinct from, but may involve aspects of, the following:

• Uniform Acts, which are model statutes produced by non-governmental bodies of legal experts to be passed by state legislatures independently, rather than constituting an agreement among multiple states;
• executive agreements between governors or statewide executive officers of states, which may or may not have the backing of statute or state constitutional law;
• State-level trigger laws which provide for an automatic action if another one or more states, or the federal government, perform a specified action; or
• State-level laws mandating, permitting or prohibiting state cooperation with another state government regarding certain actions.

Interstate agencies

Several interstate compacts may establish multi-state agencies in order to coordinate policy between, or perform tasks on behalf of, member states. Such agencies may take the form of commissions, with at least one representative from a member state. Alternatively, member states to a compact may opt for cooperation with a single independent non-profit organization which carries out designated tasks without government funding.

Legal background

The Compact Clause (Article I, Section 10, Clause 3) of the United States Constitution provides that "No State shall, without the Consent of Congress,... enter into any Agreement or Compact with another State, or with a foreign Power,..."

However, in a report released in October 2019 about the proposed National Popular Vote Interstate Compact, the Congressional Research Service (CRS) cited the U.S. Supreme Court's ruling in Virginia v. Tennessee (1893)—reaffirmed in U.S. Steel Corp. v. Multistate Tax Commission (1978) and Cuyler v. Adams (1981)—that ruled that explicit congressional consent of interstate compacts is not required for agreements "which the United States can have no possible objection or have any interest in interfering with" (in addition to ruling that the words "agreement" and "compact" used in the Compact Clause are synonyms). Instead, the Court required explicit congressional consent for interstate compacts that are "directed to the formation of any combination tending to the increase of political power in the States, which may encroach upon or interfere with the just supremacy of the United States"—meaning where the vertical balance of power between the federal government and state governments is altered in favor of state governments, while the report references U.S. Steel Corp. v. Multistate Tax Commission as stating that the "pertinent inquiry [with respect to the Compact Clause] is one of potential, rather than actual, impact on federal supremacy" in noting that the potential erosion of an enumerated power of the United States Congress by an interstate compact can arguably require explicit congressional approval. The CRS report cites the Supreme Court's rulings in Florida v. Georgia (1855) and in Texas v. New Mexico and Colorado (2018) as recognizing that explicit congressional consent is also required for interstate compacts that alter the horizontal balance of power amongst state governments.

Citing Metropolitan Washington Airports Authority v. Citizens for Abatement of Aircraft Noise, Inc. (1991) as stating that if an enumerated power under the Constitution is legislative, then "Congress must exercise it in conformity with the bicameralism and presentment requirements of Article I, Section VII", and noting that the Republican River Compact was initially vetoed by President Franklin D. Roosevelt in 1942, the CRS report states that if an interstate compact requires explicit congressional approval, it must be approved by both houses of Congress and signed into law by the President in order to become law. In Cuyler v. Adams, the Court held that congressional approval of interstate compacts makes them federal laws. The CRS report cites the Court's opinions in Virginia v. Tennessee and Northeast Bancorp v. Federal Reserve Board of Governors (1985) as stating that any agreement between two or more states that "cover[s] all stipulations affecting the conduct or claims of the parties", prohibits members from "modify[ing] or repeal[ing] [the agreement] unilaterally", and requires "'reciprocation' of mutual obligations" constitutes an interstate compact. Additionally, the CRS report cites the Court's opinion in Northeast Bancorp as suggesting that a requirement of a new interstate governmental entity is a sufficient condition for an agreement to qualify as being an interstate compact under the Compact Clause. The CRS report stated that there were approximately 200 interstate compacts in effect in 2019.

The timing for Congressional consent is not specified by the Constitution, so consent may be given either before or after the states have agreed to a particular compact. The consent may be explicit, but it may also be inferred from circumstances. Congress may also impose conditions as part of its approval of a compact. Congress must explicitly approve any compact that would give a state power that is otherwise designated to the federal government.

History

Treaties between the states, ratified under the Articles of Confederation during the period after American independence in 1776 until the current U.S. Constitution was ratified in 1789, are grandfathered and treated as interstate compacts. This includes agreements like the Treaty of Beaufort, which set the boundary between Georgia and South Carolina in 1787, and is still in effect.

Prior to 1922, most interstate compacts were either border agreements between states or advisory compacts, the latter of which are tasked with conducting joint studies to report back to the respective state legislatures. With the creation of the Port Authority of New York and New Jersey in 1922, administrative compacts began to develop as a third, more-empowered type of interstate compact, in which persistent governance structures are tasked by member states with conducting designated services.

Today, Virginia is a member of the most interstate compacts at 40, while Hawaii is a member of the fewest at 15.
