In United States constitutional law, the police power is the capacity of the states and the federal government to regulate behavior and enforce order within their territory for the betterment of the health, safety, morals, and general welfare of their inhabitants. [1] Police power is defined in each jurisdiction by the legislative body, which determines the public purposes that need to be served by legislation. [2] Under the Tenth Amendment to the United States Constitution, the powers not delegated to the federal government are reserved to the states or to the people. As a result, the police power is primarily concentrated within state governments, while the federal government possesses it in limited contexts where it has an express power, such as over conduct occurring within the territories of the United States and activities related to interstate commerce.
Police power is exercised by the legislative and executive branches of the various states through the enactment and enforcement of laws and regulations. States have the power to compel obedience to these laws through whatever measures they see fit, provided these measures do not infringe upon any of the rights protected by the United States Constitution or their own state constitutions and are not unreasonably arbitrary or oppressive. Methods of enforcement can include legal sanctions and physical means. Controversies over the exercise of state police power can arise when exercise by state authorities conflicts with individual rights and freedoms.
Most criminal cases are prosecuted in the name of the governmental authority that promulgates criminal statutes and enforces the police power of the state with the goal of seeking criminal sanctions.
The authority for use of police power under American Constitutional law has its roots in English and European common law traditions. [3] Even more fundamentally, use of police power draws on two Latin principles, sic utere tuo ut alienum non laedas ("use that which is yours so as not to injure others"), and salus populi suprema lex esto ("the welfare of the people shall be the supreme law"), to justify restriction of individual liberties in order to protect the general welfare. [3] The concept of police power in America was further expanded in a series of notable court cases in the late-nineteenth and early-twentieth centuries, including the landmark 1851 Massachusetts Supreme Judicial Court case Commonwealth v. Alger , and the 1905 Supreme Court case Jacobson v. Massachusetts .

Due to the nebulous definition of the police power, restrictions on its use are few and far between. In Commonwealth v. Alger, Chief Justice Lemuel Shaw wrote that "It is much easier to perceive and realize the existence and sources of [the police power] than to mark its boundaries, or prescribe limits to exercise." [3] However, according to historian Michael Willrich, "Shaw recognized certain constitutional restraints on police power, but they were few. Laws must apply equally to all under like circumstances... government interferences with individual rights must be 'reasonable' – they must have a clear relation to some legitimate legislative purpose. Beyond those outer limits... most courts stayed out of the way of state police power." [4] Later court cases have expanded somewhat on these restrictions by limiting the ability of states to infringe upon implied constitutional rights and by demanding a stricter standard of reasonability, but regulation of police power remains fairly minimal. [5]
Federal police power has been defined by Supreme Court rulings. In affirming that Congress has limited power to enact legislation, the court ruled in United States v. Lopez (1995) that "The Constitution...withhold[s] from Congress a plenary police power that would authorize enactment of every type of legislation." [6] [7] In United States v. Morrison (2000), the court invalidated a provision of a federal law on violent crime. The court stated, "The regulation and punishment of intrastate violence that is not directed at the instrumentalities, channels, or goods involved in interstate commerce has always been the province of the States...[W]e can think of no better example of the police power, which the Founders denied the National Government and reposed in the States, than the suppression of violent crime..." [6] [8]
The police power is the basis for land-use planning authority in the United States. This authority is usually delegated by state governments to local governments, including counties and municipalities, which most frequently exercise police power in land-use planning matters. Such regulation based on police power is distinct from the government's taking of private property through the power of eminent domain—under the authority of the police power, a private property owner is not typically entitled to compensation. The decision by the Massachusetts Supreme Judicial Court in the case Commonwealth v. Alger (1851) was related to land-use planning and dealt with the construction of a wharf on privately-owned tidelands around Boston Harbor. [9]
Jurisdiction is the legal term for the legal authority granted to a legal entity to enact justice. In federations like the United States, the concept of jurisdiction applies at multiple levels.
The Tenth Amendment to the United States Constitution, a part of the Bill of Rights, was ratified on December 15, 1791. It expresses the principle of federalism, also known as states' rights, by stating that the federal government has only those powers delegated to it by the Constitution, and that all other powers not forbidden to the states by the Constitution are reserved to each state, or to the people.
The Commerce Clause describes an enumerated power listed in the United States Constitution. 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.
Mapp v. Ohio, 367 U.S. 643 (1961), was a landmark decision of the U.S. Supreme Court in which the Court ruled that the exclusionary rule, which prevents prosecutors from using evidence in court that was obtained by violating the 4th Amendment to the U.S. Constitution, applies not only to the federal government but also to the state governments. The Supreme Court accomplished this by use of a principle known as selective incorporation.
City of Boerne v. Flores, 521 U.S. 507 (1997), was a landmark decision of the Supreme Court of the United States concerning the scope of Congress's power of enforcement under Section 5 of the Fourteenth Amendment. The case also had a significant impact on historic preservation.
The Preamble to the United States Constitution, beginning with the words We the People, is a brief introductory statement of the US Constitution's fundamental purposes and guiding principles. Courts have referred to it as reliable evidence of the Founding Fathers' intentions regarding the Constitution's meaning and what they hoped the Constitution would achieve.
Separation of powers is a political doctrine originating in the writings of Charles de Secondat, Baron de Montesquieu in The Spirit of the Laws, in which he argued for a constitutional government with three separate branches, each of which would have defined abilities to check the powers of the others. This philosophy heavily influenced the drafting of the United States Constitution, according to which the Legislative, Executive, and Judicial branches of the United States government are kept distinct in order to prevent abuse of power. The American form of separation of powers is associated with a system of checks and balances.
In many Commonwealth jurisdictions, the phrase "peace, order, and good government" (POGG) is an expression used in law to express the legitimate objects of legislative powers conferred by statute. The phrase appears in many Imperial Acts of Parliament and Letters Patent, most notably the constitutions of Barbados, Canada, Australia and formerly New Zealand and South Africa.
The enumerated powers of the United States Congress are the powers granted to the federal government of the United States by the United States Constitution. Most of these powers are listed in Article I, Section 8.
The Taxing and Spending Clause, Article I, Section 8, Clause 1 of the United States Constitution, grants the federal government of the United States its power of taxation. While authorizing Congress to levy taxes, this clause permits the levying of taxes for two purposes only: to pay the debts of the United States, and to provide for the common defense and general welfare of the United States. Taken together, these purposes have traditionally been held to imply and to constitute the federal government's taxing and spending power.
In the United States, judicial review is the legal power of a court to determine if a statute, treaty, or administrative regulation contradicts or violates the provisions of existing law, a State Constitution, or ultimately the United States Constitution. While the U.S. Constitution does not explicitly define the power of judicial review, the authority for judicial review in the United States has been inferred from the structure, provisions, and history of the Constitution.
South Carolina v. Katzenbach, 383 U.S. 301 (1966), was a landmark decision of the US Supreme Court that rejected a challenge from the state of South Carolina to the preclearance provisions of the Voting Rights Act of 1965, which required that some states submit changes in election districts to the Attorney General of the United States. The preclearance provisions were ruled constitutional and the Voting Rights Act of 1965 was enforced in full.
Nullification, in United States constitutional history, is a legal theory that a state has the right to nullify, or invalidate, any federal laws which they deem unconstitutional with respect to the United States Constitution. There are similar theories that any officer, jury, or individual may do the same. The theory of state nullification has never been legally upheld by federal courts, although jury nullification has.
Jacobson v. Massachusetts, 197 U.S. 11 (1905), was a United States Supreme Court case in which the Court upheld the authority of states to enforce compulsory vaccination laws. The Court's decision articulated the view that individual liberty is not absolute and is subject to the police power of the state. Jacobson has been invoked in numerous other Supreme Court cases as an example of a baseline exercise of the police power.
Smith v. Turner; Norris v. Boston, 48 U.S. 283 (1849), were two similar cases, argued together before the United States Supreme Court, which decided 5–4 that states do not have the right to impose a tax that is determined by the number of passengers of a designated category on board a ship and/or disembarking into the State. The cases are sometimes called the Passenger Case or Passenger Cases.
In the United States, a state is a constituent political entity, of which there are 50. Bound together in a political union, each state holds governmental jurisdiction over a separate and defined geographic territory where it shares its sovereignty with the federal government. Due to this shared sovereignty, Americans are citizens both of the federal republic and of the state in which they reside. State citizenship and residency are flexible, and no government approval is required to move between states, except for persons restricted by certain types of court orders.
Commonwealth v. Alger, 61 Mass. 53, was decided by the Supreme Judicial Court of Massachusetts in 1851. The majority opinion was written by Justice Lemuel Shaw.
The law of the United States comprises many levels of codified and uncodified forms of law, of which the most important is the nation's Constitution, which prescribes the foundation of the federal government of the United States, as well as various civil liberties. The Constitution sets out the boundaries of federal law, which consists of Acts of Congress, treaties ratified by the Senate, regulations promulgated by the executive branch, and case law originating from the federal judiciary. The United States Code is the official compilation and codification of general and permanent federal statutory law.
The Supremacy Clause of the Constitution of the United States establishes that the Constitution, federal laws made pursuant to it, and treaties made under its authority, constitute the "supreme Law of the Land", and thus take priority over any conflicting state laws. It provides that state courts are bound by, and state constitutions subordinate to, the supreme law. However, federal statutes and treaties must be within the parameters of the Constitution; that is, they must be pursuant to the federal government's enumerated powers, and not violate other constitutional limits on federal power, such as the Bill of Rights—of particular interest is the Tenth Amendment to the United States Constitution, which states that the federal government has only those powers that are delegated to it by the Constitution. It is the responsibility of the United States Supreme Court in that case to exercise the power of judicial review: the ability to invalidate a statute for violating a provision of the Constitution.
Lambert v. Yellowley, 272 U.S. 581 (1926), was a decision by the Supreme Court of the United States that reaffirmed the National Prohibition Act's limitation on the dispensation of alcoholic medicines. The five-to-four decision, written by Justice Louis D. Brandeis, affirmed the dismissal of a suit in which New York City physician Samuel Lambert sought to prevent Edward Yellowley, the acting federal prohibition director, from enforcing the Prohibition Act so as to preclude him from prescribing alcoholic medicines. The decision affirmed the police powers of the individual states, as well as the power of the Necessary and Proper Clause of the United States Constitution, which was cited in upholding the Prohibition Act's limitations as a necessary and proper implementation of the Eighteenth Amendment to the United States Constitution.
