Federal Abstention from State Prosecution
State prosecutors charged Cassandra Cooper with a crime under a state statute. She filed a federal suit seeking to enjoin the ongoing prosecution on constitutional grounds. The federal court declined to intervene because principles of comity required deference to the state proceeding absent extraordinary circumstances.
Recognition of Sister-State Judgment
Charles Cunningham obtained a judgment in State A against a debtor whose property lay in State B. When he sought enforcement in State B, the court honored the judgment under principles of comity even though the original court lacked direct power over the out-of-state land.
In February 1866, J.H. Mitchell obtained a judgment in an Oregon circuit court against Neff for less than $300 in an action for attorney services.
At that time, Neff resided outside Oregon, received no personal service of process, and made no appearance in the case. The judgment was entered by default following constructive service by publication as authorized by the Oregon Code for non-resident defendants possessing property within the state.
The Oregon Code also provided for attachment of a non-resident's property in money actions. No such attachment occurred with respect to the land at issue. Instead, after the judgment, an execution issued, leading to a levy on the land and its sale at a sheriff's auction.
Pennoyer purchased the property at that sale and received a sheriff's deed. Separately, in 1866, the United States issued a patent to Neff for the same tract of land under the Donation Law of Oregon, which Neff valued at $15,000. Neff then brought suit against Pennoyer in the circuit court to recover possession of the premises based on his patent title.
The lower court held the Oregon judgment invalid because of deficiencies in the affidavits used to obtain the publication order and to prove publication occurred. The Supreme Court of the United States granted review to consider the validity of the state court judgment and the resulting sheriff's sale.
Craig Caldwell sued in federal court on a federal claim and added related state claims. After the federal claim was dismissed early, the court declined to keep the state claims, citing comity and the preference that state courts resolve purely state-law disputes.
United Mine Workers of America v. Gibbs383 U.S. 715, 724 (1966)
Paul Gibbs was hired in the summer of 1960 by Grundy Company, a wholly owned subsidiary of Tennessee Consolidated Coal Company, to serve as mine superintendent for a new mine at Gray's Creek and to haul the coal produced there under a separate contract. This arrangement occurred amid ongoing rivalry between the United Mine Workers of America and the Southern Labor Union for representation of coal miners in the southern Appalachian fields.
On August 15 and 16, 1960, armed members of UMW Local 5881 prevented the mine from opening through threats and violence, including beating an organizer for the rival union, after learning that jobs they believed had been promised to them were going to others. George Gilbert, the UMW field representative for the area, was attending an Executive Board meeting in Middlesboro, Kentucky, when the violence occurred and did not return until late on August 16.
Upon his return he received instructions from international union superiors to establish a limited picket line, prevent any further violence, and ensure the strike did not spread. No further violence took place at the mine site, a picket line was maintained for nine months, and no further attempts were made to open the mine during that period. Gibbs lost his superintendent position and never performed the haulage contract.
He claimed to have lost other trucking contracts and mine leases in nearby areas as a result of a concerted union plan against him. He filed suit against the international UMW only, not against Local 5881 or its members, in the United States District Court for the Eastern District of Tennessee.
Jurisdiction over the federal claim rested on alleged secondary boycotts under section 303 of the Labor Management Relations Act. Jurisdiction over the state law claim for unlawful conspiracy and boycott was premised on the doctrine of pendent jurisdiction. At trial the district court refused to submit claims of pressure on mining firms other than Grundy to cease doing business with Gibbs. The jury returned a verdict finding violations of both section 303 and state law and awarded $60,000 in damages under the employment contract, $14,500 under the haulage contract, and $100,000 in punitive damages. On post-trial motion the court set aside the haulage contract award for lack of proof of damages and sustained a remitted award on the state law claim alone. The Court of Appeals for the Sixth Circuit affirmed, and the Supreme Court granted certiorari.
Charlotte Chung challenged a city zoning ordinance that restricted extended family living arrangements in her home. The court upheld the ordinance after weighing comity concerns and deferring to the state's traditional authority over local land-use rules.
Moore v. City of East Cleveland, Ohio431 U.S. 494, 503 (1977)
In early 1973, Mrs. Inez Moore received a notice of violation from the city of East Cleveland. The notice stated that her grandson John Moore, Jr., was an illegal occupant of her home. It directed her to comply with the housing ordinance.
Mrs. Moore lived in her East Cleveland home together with her son Dale Moore, Sr., and her two grandsons Dale Moore, Jr., and John Moore, Jr. John came to live with her after his mother's death when he was less than one year old. When she failed to remove John from the home, the city filed a criminal charge against her.
Mrs. Moore moved to dismiss the charge. She claimed that the ordinance was constitutionally invalid on its face. Her motion was overruled. Upon conviction she was sentenced to five days in jail and a $25 fine.
The East Cleveland ordinance limited occupancy of a dwelling unit to members of a single family. The ordinance defined family to include only a husband or wife of the nominal head of the household, unmarried children of the head or spouse provided they have no children residing with them, a parent of the head or spouse, or not more than one dependent child of the head or spouse along with that child's spouse and dependent children.
The Ohio Court of Appeals affirmed the conviction after giving full consideration to her constitutional claims. The Ohio Supreme Court denied review of the case. The United States Supreme Court noted probable jurisdiction of her appeal.
Colin Chambers sued to enjoin a state education program that used federal funds for certain services. The court applied comity principles and allowed the program to continue while the state courts addressed the underlying statutory questions first.
Agostini v. Felton521 U.S. 203 (1997)
In 1965, Congress enacted Title I of the Elementary and Secondary Education Act to provide remedial education services to disadvantaged children. The Board of Education of the City of New York first applied for Title I funds in 1966 and initially arranged to transport eligible private school students to public schools for after-school instruction. When that approach proved unsuccessful due to poor attendance and safety concerns, the Board implemented an on-site program in 1978 that sent public school teachers into parochial schools during regular school hours.
In 1978, respondents, who are parents of parochial school children and federal taxpayers, sued the Board in the District Court for the Eastern District of New York challenging the on-site program as violating the Establishment Clause. The District Court enjoined the on-site services in 1981, and the Court of Appeals for the Second Circuit affirmed the following year. While the appeal was pending, the Board developed an off-premises program that required transporting students to neutral sites at an estimated additional cost of $6 million per year.
In 1983, the parties entered into a consent decree requiring the Board to provide Title I services off the premises of sectarian schools and to establish a monitoring system. Following the Supreme Court's 1985 decision in Aguilar v. Felton, which invalidated a similar program, the parties entered a second consent decree that required the Board to pay for the additional costs of the off-premises program. The Board complied with both decrees, spending over $100 million on computer-aided instruction, leased sites, and transportation between the 1986-1987 and 1993-1994 school years.
In 1995, the Board and a group of parents of parochial school students moved in the District Court for relief from the consent decrees under Federal Rule of Civil Procedure 60(b)(5), citing subsequent decisions including Zobrest v. Catalina Foothills School District and Witters v. Washington Department of Services for the Blind. The District Court denied the motion, concluding that Aguilar remained good law and that no significant change in factual conditions had been shown. The Court of Appeals affirmed, and the Supreme Court granted certiorari in 1997.
Canyon Construction operated vessels under a federal license but faced conflicting state regulations. The court invoked comity to reconcile the overlapping rules rather than allowing one sovereign to nullify the other's legitimate authority.
Gibbons v. Ogden22 U.S. (9 Wheat.) 1, 211 (1824)
In 1798 the New York Legislature granted Robert R. Livingston and Robert Fulton the exclusive right for twenty years to navigate the waters within the jurisdiction of the state with boats moved by fire or steam, a privilege later renewed and extended in 1803 and 1807. The right was assigned first to John R. Livingston and then to Aaron Ogden, who thereby claimed authority to operate steamboats between Elizabethtown, New Jersey, and New York City. Thomas Gibbons, meanwhile, took possession of two steamboats, the Stoudinger and the Bellona, which he employed in the same waters while holding a license issued under the federal Act of February 18, 1793, for enrolling and licensing vessels to be employed in the coasting trade and fisheries.
Gibbons filed a bill in the Court of Chancery of New York against Ogden seeking an injunction to restrain Ogden from navigating those waters with steamboats. The bill recited the state grants and the assignment to Ogden, alleged that Ogden was violating the exclusive privilege, and prayed for injunctive relief. Gibbons answered that his vessels were duly enrolled and licensed under the 1793 federal statute and insisted on his right to navigate between Elizabethtown and New York notwithstanding the state legislation.
The Chancellor awarded the injunction and, after hearing, perpetuated it on the ground that the New York acts were valid. The Court for the Trial of Impeachments and Correction of Errors, the highest court of the state to which the cause could be carried, affirmed the decree. Gibbons then appealed to the Supreme Court of the United States.
When may a federal court decline supplemental jurisdiction over state claims on comity grounds?
A federal court may decline supplemental jurisdiction when the state claims raise novel or complex issues of state law, substantially predominate over federal claims, or when all federal claims have been dismissed. Comity favors allowing state courts to decide questions of state law in the first instance.
Does comity require a state court to recognize a foreign support order?
A state tribunal may recognize and enforce a foreign support order on the basis of comity even when the Uniform Interstate Family Support Act does not directly apply. The tribunal may then use the procedural and substantive provisions of the Act for enforcement.
How does comity interact with a state's sovereign immunity in another state's courts?
Comity does not override constitutional state sovereign immunity. A state may not be sued for damages in another state's courts without its consent, and principles of comity cannot force recognition of jurisdiction over a nonconsenting sovereign.
95 U.S. 714 (1878)
…an elementary principle, that the laws of one State have no operation outside of its territory, except so far as is allowed by comity; and that no tribunal established by it can extend its process beyond that territory so as to subject either persons or property to its decisions. "Any exertion of authority of this sort…
