A state's inherent authority to enact legislation promoting the public health, safety, morals, or general welfare. The power extends to reasonable regulations of land use, business practices, and individual conduct so long as the measures bear a substantial relation to those public ends and do not violate federal constitutional limits.

City Zoning Districts Upheld
Gretchen Graham owns acreage on the edge of a growing municipality. The city council adopts an ordinance that divides the area into residential, commercial, and industrial districts and bars industrial uses on her parcel. The classification is reasonable and advances public health and welfare, so the ordinance stands as a valid exercise of the general police power.
Federal Gun Ban Rejected
Gina Griffin, a local volunteer, carries an unloaded rifle in her truck while cleaning a stream near a school. Congress has banned such possession under the commerce power. The statute exceeds federal authority because the activity is noneconomic and intrastate, leaving the matter to the state's general police power.
In March 1992, Alfonso Lopez, Jr., a twelfth-grade student at Edison High School in San Antonio, Texas, arrived at school carrying a concealed .38-caliber handgun and five bullets. Acting on an anonymous tip, school authorities confronted Lopez, who admitted possessing the weapon. Local police arrested him and charged him under Texas law with firearm possession on school premises.
The following day, state charges were dismissed after federal agents charged Lopez with violating the Gun-Free School Zones Act of 1990. A federal grand jury indicted him on one count of knowing possession of a firearm at a school zone. Lopez moved to dismiss the indictment, arguing that the statute exceeded Congress's power to legislate control over public schools.
The district court denied the motion, concluding that the statute was a constitutional exercise of Congress's power to regulate activities affecting commerce because the business of schools affects interstate commerce. After a bench trial, the court found Lopez guilty and sentenced him to six months' imprisonment and two years of supervised release.
Lopez appealed to the Court of Appeals for the Fifth Circuit, which reversed the conviction, holding that the statute was beyond Congress's power under the Commerce Clause. The Supreme Court granted certiorari to review the case.
Gerald Gibson owns a bakery and requires employees to work more than sixty hours a week. A state statute caps hours to protect worker health. The law is invalidated because it interferes with liberty of contract without a sufficient connection to public welfare under the general police power.
Lochner v. New York198 U.S. 45 (1905)
The New York legislature passed a labor law in 1897 that regulated bakeries and confectionery establishments.
Section 110 of article 8 of that law stated that no employee shall be required or permitted to work more than sixty hours in any one week or more than ten hours in any one day.
This applied unless for the purpose of making a shorter work day on the last day of the week.
The plaintiff in error violated the one hundred and tenth section of article 8, chapter 415, of the Laws of 1897, known as the labor law of the State of New York, in that he wrongfully and unlawfully required and permitted an employe working for him to work more than sixty hours in one week. The charge arose from a voluntary contract rather than any use of physical force.
The judgments of the County Court of Oneida County, the Supreme Court, and the Court of Appeals of New York upheld the conviction under the statute, although several judges dissented. The record indicated that the state courts had viewed the law as a measure relating to public health.
The case came before the Supreme Court of the United States after argument on February 23 and 24, 1905. The Court rendered its decision on April 17, 1905.
Grace Gupta owns a lot needed for a public street widening. The city condemns a strip of land and pays compensation. The taking is upheld as an exercise of eminent domain authority that remains subject to the limits that also constrain the general police power.
Chicago, Burlington & Quincy Railroad Co. v. City of Chicago166 U.S. 226, 239, 17 S.Ct. 581, 585, 41 L.Ed. 979 (1897)
The City of Chicago, acting under an 1872 Illinois statute that became part of its charter in 1875, passed an ordinance on October 9, 1880, to open and widen Rockwell Street from West 18th Street to West 19th Street by condemning parcels of land owned by individuals and parts of the right of way of the Chicago, Burlington and Quincy Railroad Company within the city limits.
On November 12, 1890, the city filed a petition in the Circuit Court of Cook County seeking condemnation of the property and asking that just compensation be ascertained by a jury, with the railroad company admitted as a defendant along with other interested parties. The jury awarded one dollar as just compensation to the railroad company for the parts of its right of way to be used for the street, while awarding compensation to individual owners for their parcels.
The railroad moved for a new trial, which was overruled, and final judgment was entered in execution of the award. The judgment was affirmed by the Supreme Court of Illinois in 149 Illinois 457. After affirmance the railroad company sued out a writ of error to the United States Supreme Court.
The railroad had raised claims under the Fourteenth Amendment in its motion for new trial and in its assignment of errors filed in the state supreme court. The Illinois statute provided no provision for an answer by defendants in condemnation proceedings, but the railroad asserted its federal claims in the written motion to set aside the verdict and grant a new trial.
Genevieve Gardner's waterfront property is condemned for a private redevelopment project expected to increase tax revenue and jobs. The taking is sustained as satisfying the public-use requirement, an eminent-domain doctrine that operates alongside the general police power.
Kelo, et al. v. City of New London545 U.S. 469, 503 (2005)
In the late 1990s the city of New London, Connecticut, confronted severe economic decline after the 1996 closure of the Naval Undersea Warfare Center, which had employed more than 1,500 people. The city's unemployment rate stood nearly double the state average and its population had dropped below 24,000 residents from a 1970 high of 30,000. State and local officials therefore designated the Fort Trumbull peninsula for targeted economic revitalization.
In 1998 the New London Development Corporation, a private nonprofit entity, was reactivated to prepare a redevelopment plan covering roughly 90 acres. The plan divided the area into seven parcels designated for a waterfront conference hotel and marinas, retail and entertainment space, research and office facilities, parking and park support, residential units, a Coast Guard museum, and additional office and retail uses. The city council formally approved the plan in January 2000 and authorized the NLDC to acquire needed parcels by purchase or, if necessary, by eminent domain.
Petitioners Susette Kelo, Wilhelmina Dery, and seven other owners held fifteen properties within parcels 3 and 4A; ten of those parcels were occupied by the owners or their family members and none was alleged to be blighted. After negotiations with the NLDC failed, the corporation initiated condemnation proceedings against the remaining properties in November 2000.
In December 2000 the petitioners filed suit in New London Superior Court asserting that the proposed takings violated the public-use limitation of the Fifth Amendment. Following a seven-day bench trial the Superior Court entered a permanent restraining order barring condemnation of the parcel 4A properties but denied relief as to the parcel 3 properties.
Both sides appealed to the Connecticut Supreme Court, which upheld the validity of all challenged takings. The United States Supreme Court granted certiorari to review the federal constitutional question.
Gideon Graves's religious group plans to sacrifice animals in accordance with its faith. A city ordinance bans the practice under the guise of public health. The law is struck down because it targets religious conduct and therefore exceeds the bounds of the general police power.
Church of the Lukumi Babalu Aye, Inc. v. City of Hialeah508 U.S. 520, 113 S. Ct. 2217, 124 L. Ed. 2d 472 (1993)
In April 1987 the Church of the Lukumi Babalu Aye, Inc., a not-for-profit corporation organized under Florida law in 1973 whose president is Ernesto Pichardo, leased land in Hialeah, Florida, and announced plans to build a house of worship, school, cultural center, and museum at which members would practice Santeria.
Santeria originated in nineteenth-century Cuba as a fusion of Yoruba traditions and Roman Catholicism. It centers on animal sacrifice performed by cutting the carotid arteries, after which the animals are usually cooked and eaten except in healing and death rituals. The announcement prompted the Hialeah City Council to convene an emergency public session on June 9, 1987.
At that session residents and council members voiced strong opposition to Santeria practices. The council then adopted Resolution 87-66 declaring opposition to religious acts inconsistent with public morals, peace, or safety and passed Ordinance 87-40 incorporating Florida's animal-cruelty statute that criminalizes unnecessary or cruel killing of animals.
After the Florida attorney general issued an opinion that ritual animal sacrifice other than for food consumption violated state law, the council in August 1987 adopted Resolution 87-90 opposing ritual animal sacrifice. In September 1987 the council enacted three further ordinances. Ordinance 87-52 barred possession of animals with intent to use them for ritual sacrifice except by licensed food establishments. Ordinance 87-71 directly prohibited any person from sacrificing an animal within city limits. Ordinance 87-72 restricted slaughter of animals to properly zoned slaughterhouse premises while exempting small-scale commercial hog and cattle operations.
The Church and Pichardo filed suit against the city and its officials in the United States District Court for the Southern District of Florida under 42 U.S.C. § 1983. They alleged that the ordinances violated their rights under the Free Exercise Clause. After granting summary judgment to the individual defendants on immunity grounds, the district court conducted a nine-day bench trial on the remaining claims and entered judgment for the city. The Court of Appeals for the Eleventh Circuit affirmed in a one-paragraph per curiam opinion. The Supreme Court granted certiorari.
How does the general police power differ from federal authority?
States may enact any law that promotes public health, safety, morals, or welfare without citing a specific constitutional grant. The federal government must identify an enumerated power such as the commerce clause and may not rely on a general police power.
Does the general police power allow zoning ordinances?
Yes. Comprehensive zoning that divides land into districts and restricts uses is a valid exercise of the general police power when the classification is reasonable and substantially related to public health, safety, morals, or welfare.
Can the general police power override federal constitutional limits?
No. State exercises of the general police power remain subject to federal constitutional restraints such as the contracts clause, due process, equal protection, and the free exercise clause.
