Probate Court Applies Prior Ruling
Jillian James drafted a will leaving her estate to her nephew if he survived her. After her death the nephew predeceased her, and the probate court followed an earlier decision interpreting identical language in another estate to treat the residuary clause as creating an alternative devise that prevented lapse.
Judge Recuses Over Financial Stake
James Johnson sat as plaintiff in pending litigation whose outcome would gain value from a precedent the current case would set. The reviewing court vacated the judgment and remanded for decision by a judge lacking any direct economic interest in the result.
Jonathan Jaffe challenged an agency rule as exceeding statutory authority. The court applied an earlier decision that limited judicial review of agency procedures and upheld the rule because the agency had followed required steps.
Vermont Yankee Nuclear Power Corp. v. Nat. Res. Def. Council, Inc.467 U.S. 837, 843, 104 S. Ct. 2778, 2781, 81 L. Ed. 2d 694 (1984)
In 1967 the Atomic Energy Commission granted Vermont Yankee a construction permit for a nuclear power plant in Vernon, Vermont, after the required adjudicatory hearing and reviews. Vermont Yankee later applied for an operating license; NRDC intervened and objected to exclusion of fuel-reprocessing and waste-disposal impacts from the hearing. In November 1972 the Commission opened a separate rulemaking proceeding on those fuel-cycle issues, noticed two alternative approaches based on its Environmental Survey, and conducted a February 1973 hearing at which more than forty participants submitted comments but no discovery or cross-examination occurred. In April 1974 the Commission adopted a rule assigning numerical values to fuel-cycle impacts and applied it prospectively.
In January 1969 Consumers Power applied for permits to build two nuclear reactors in Midland, Michigan. After staff and ACRS review, Saginaw and Mapleton intervened and raised 119 environmental contentions, including seventeen on energy conservation. The Licensing Board held hearings on radiological issues, the staff issued a final environmental impact statement in March 1972, and further hearings occurred in May and June 1972; Saginaw declined to participate in the later hearings or submit proposed findings. The Licensing Board granted the construction permit, the Appeal Board affirmed, and the Commission declined further review. In November 1973 the Commission ruled in another case that energy-conservation evidence meeting threshold tests could be considered, but it later refused Saginaw's motion to reopen the Consumers Power record.
NRDC appealed the Vermont Yankee license and rule to the D.C. Circuit; Saginaw and others appealed the Consumers Power permit. In 1976 the Court of Appeals remanded both matters, holding the fuel-cycle rulemaking procedures inadequate, the Consumers Power environmental impact statement defective for omitting energy conservation, and the ACRS report insufficiently explained. The Supreme Court granted certiorari in 1977.
The Commission is the successor agency to the Atomic Energy Commission under the Energy Reorganization Act of 1974. All licensing proceedings followed the two-stage process of construction permit followed by operating license under the Atomic Energy Act of 1954, with NEPA environmental reviews added after 1969.
Jose Jimenez sued a newspaper for publishing critical statements about his official conduct. The court applied an earlier decision requiring proof of actual malice and dismissed the claim for failure to meet that standard.
New York Times v. Sullivan376 U.S. 254 (1964)
L. B. Sullivan is one of three elected Commissioners of the City of Montgomery, Alabama. He has duties including supervision of the Police Department. He brought this civil libel action against the New York Times Company and four individual petitioners who were Alabama clergymen. The suit sought $500,000 in damages based on a full-page advertisement entitled "Heed Their Rising Voices" that appeared in the New York Times on March 29, 1960. A jury in the Circuit Court of Montgomery County awarded Sullivan the full amount claimed against all petitioners. The Supreme Court of Alabama affirmed the judgment.
The advertisement was signed by the Committee to Defend Martin Luther King and the Struggle for Freedom in the South. It described widespread non-violent demonstrations by Southern Negro students and an unprecedented wave of terror against them. Two paragraphs formed the basis of the claim. One alleged that after students sang on the State Capitol steps their leaders were expelled, truckloads of police ringed the Alabama State College Campus, and the dining hall was padlocked to starve students into submission. The other stated that Southern violators had bombed Dr. King's home, assaulted him, arrested him seven times, and charged him with perjury. The text appeared over the names of 64 persons. It was endorsed by the individual petitioners among others.
Sullivan contended that the references to police referred to him in his supervisory capacity. Six Montgomery residents testified that they read the statements as referring to him. However, several statements were inaccurate. The students sang the National Anthem rather than "My Country, 'Tis of Thee." The expulsions were for a different incident. The dining hall was not padlocked. Dr. King had been arrested only four times. The bombings occurred before Sullivan's tenure with police efforts to apprehend the perpetrators.
The Times published the advertisement for approximately $4800. It acted upon an order from a New York advertising agency. The agency provided a letter from A. Philip Randolph certifying authorization. The Times made no efforts to confirm its accuracy against its own news files.
Sullivan served written demands for retraction on the petitioners pursuant to Alabama law. None of the individual petitioners responded as they had not authorized use of their names. The Times did not retract. It published a retraction only upon demand by Governor John Patterson after learning more facts. The Supreme Court granted certiorari to the separate petitions of the individual petitioners and the Times due to the importance of the constitutional issues involved.
Jessica Jacobs opposed a city's taking of her property for economic redevelopment. The court followed an earlier decision permitting such takings when they serve a public purpose and upheld the condemnation.
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.
Jerome Jackson sought recognition of his out-of-state same-sex marriage. The court applied an earlier decision holding that the fundamental right to marry extends to same-sex couples and ordered the state to recognize the marriage.
Obergefell v. Hodges576 U.S. 644 (2015)
The petitioners were fourteen same-sex couples and two men whose same-sex partners were deceased. They lived in Michigan, Kentucky, Ohio, and Tennessee. Those states defined marriage as a union between one man and one woman under their constitutions and statutes.
The petitioners filed suits in federal district courts in their home states. They sought marriage licenses or recognition of marriages lawfully performed elsewhere. James Obergefell and John Arthur traveled from Ohio to Maryland to marry aboard a medical transport plane because Arthur suffered from ALS; Obergefell later sought to be listed as surviving spouse on Arthur's death certificate. April DeBoer and Jayne Rowse, Michigan nurses, adopted three children but could not both serve as legal parents under state adoption rules. Army Reserve Sergeant Ijpe DeKoe and Thomas Kostura married in New York before DeKoe's deployment to Afghanistan and later settled in Tennessee.
Each district court ruled in the petitioners' favor. The respondents appealed. The Sixth Circuit consolidated the cases and reversed the district court judgments. The petitioners sought certiorari, which the Supreme Court granted.
Same-sex couples had begun establishing families after substantial cultural and political developments in the late twentieth century. Earlier litigation had addressed the legal status of gays and lesbians, including challenges that reached the Supreme Court in Bowers v. Hardwick and Lawrence v. Texas.
How does a court decide whether an earlier decision qualifies as binding precedent?
A court examines whether the facts and legal issues in the earlier case are substantially similar to those in the current dispute. If the cases share the same controlling rule and facts, the earlier holding governs the outcome.
What happens when a judge has a financial interest that could be affected by the precedent the case will set?
The judge must recuse because the risk of bias violates due process. The judgment is vacated and the matter is remanded for decision by a neutral tribunal.
Can a state court decision that blends state and federal analysis be reviewed by the U.S. Supreme Court?
Yes. When the state court does not clearly state that it rests on independent state grounds, the Supreme Court presumes a federal basis and exercises jurisdiction.
