Equal Parent-Child Status in Succession
Isabelle Inman and her partner never married but raised two children together. After Isabelle died intestate, the probate court applied in aequo principles to recognize both children as her heirs with full rights under the uniform probate rules, allowing them to inherit equally without regard to the parents' marital status.
Equitable Division of After-Acquired Collateral
Lender Bank and Borrower Corp disputed priority in commingled inventory. Although a later security interest was perfected first, the court applied in aequo principles to rank the interests equally in proportion to collateral value at the time of commingling.
Penn Central Transportation Co. et al. v. New York City438 U.S. 104, 98 S.Ct. 2646, 57 L.Ed.2d 631 (1978)
In 1965 New York City enacted the Landmarks Preservation Law, which created an eleven-member Landmarks Preservation Commission and authorized it to designate buildings at least thirty years old that possess special historical or aesthetic interest.
The law required owners of designated landmarks to obtain Commission approval before altering exterior architectural features and imposed an affirmative duty to keep those features in good repair. In August 1967 the Commission designated Grand Central Terminal a landmark and the city tax block it occupies a landmark site; the Board of Estimate confirmed the designation the following month.
Penn Central Transportation Co. and its affiliates owned the Terminal, an eight-story Beaux-Arts structure completed in 1913 that served as the main station for the New York Central and Harlem lines. On January 22, 1968, Penn Central entered a fifty-year renewable lease with UGP Properties, Inc., under which UGP agreed to construct a multistory office building cantilevered above the Terminal and to pay Penn Central at least three million dollars annually after construction.
Penn Central and UGP submitted two plans prepared by architect Marcel Breuer: Breuer I, a fifty-five-story tower resting on the Terminal roof, and Breuer II Revised, a fifty-three-story building that would have removed part of the 42d Street facade. After four days of hearings at which over 80 witnesses testified, the Commission denied this application as to both proposals.
Penn Central filed suit in New York Supreme Court, Trial Term, seeking a declaratory judgment, injunctive relief, and damages for a temporary taking. The trial court granted the injunctive and declaratory relief. The Appellate Division reversed, holding that Penn Central had failed to prove deprivation of all reasonable beneficial use. The New York Court of Appeals affirmed, concluding that the Terminal could still earn a reasonable return and that transferable development rights provided significant compensation. The Supreme Court noted probable jurisdiction.
Icarus Aviation challenged new nuclear safety regulations. The court applied in aequo equitable standards to determine whether the agency had considered all relevant factors before upholding the rules.
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.
Irene Ingalls faced deportation after a legislative veto. The court applied in aequo principles to require bicameral action and presentment rather than strict procedural rules.
Immigration & Naturalization Service v. Jagdish Rai Chadha462 U.S. 919, 954 n. 16, 103 S.Ct. 2764, 2785 n. 16, 77 L.Ed.2d 317
In 1966 Jagdish Rai Chadha, an East Indian born in Kenya who held a British passport, was lawfully admitted to the United States on a nonimmigrant student visa that expired on June 30, 1972. In October 1973, the District Director of the Immigration and Naturalization Service informed Chadha that he had remained longer than permitted and was therefore deportable. Chadha conceded deportability but applied for suspension under section 244(a)(1) of the Immigration and Nationality Act of 1952.
On June 25, 1974, an Immigration Judge acting on behalf of the Attorney General suspended Chadha's deportation and adjusted his status to permanent resident after finding that he satisfied the statutory criteria of seven years' continuous presence, good moral character, and extreme hardship. A report of the suspension was transmitted to Congress as required by the Act.
On December 16, 1975, the House of Representatives passed a resolution disapproving the suspension for Chadha and five other aliens on the ground that they did not meet the statutory requirements, particularly as to hardship.
Pursuant to the House resolution, the Immigration Judge reopened the deportation proceedings. Chadha moved to terminate them on constitutional grounds, but the Immigration Judge ruled that he lacked authority to declare the resolution unconstitutional and ordered Chadha deported. Chadha appealed to the Board of Immigration Appeals, which likewise held that it had no authority to pass on the constitutionality of the resolution and dismissed the appeal.
Chadha then filed a petition for review in the United States Court of Appeals for the Ninth Circuit. The Immigration and Naturalization Service appeared and urged the court to hold the House resolution unconstitutional. After inviting briefs from the Senate and House as amici curiae, the Court of Appeals held the resolution unconstitutional because it was a legislative act that failed to satisfy the requirements of Article I, sections 1 and 7, and set aside the deportation order.
The Supreme Court granted certiorari in the consolidated cases to address the constitutional question.
Ibrahim Iqbal sought physician assistance to end terminal illness. The court applied in aequo equitable principles to weigh fundamental liberty interests against state prohibition rather than rigid due-process rules.
Washington v. Glucksberg521 U.S. 702 (1997)
Washington has prohibited assisting suicide since its territorial days. In 1854, the first Territorial Legislature outlawed assisting another in the commission of self-murder. The current statute, Wash. Rev. Code § 9A.36.060, provides that a person is guilty of promoting a suicide attempt when he knowingly causes or aids another person to attempt suicide, and classifies it as a class C felony punishable by up to five years imprisonment and a $10,000 fine. Washington's Natural Death Act, enacted in 1979, states that the withholding or withdrawal of life-sustaining treatment at a patient's direction shall not constitute a suicide, but the state has consistently rejected efforts to legalize physician-assisted suicide, including a 1991 ballot initiative defeated by voters.
The respondents in this case are four physicians who practice in Washington and treat terminally ill patients, three terminally ill patients who sought to end their lives with physician assistance and have since died, and Compassion in Dying, a nonprofit organization that counsels people considering physician-assisted suicide. The physicians declared that they would assist their patients in ending their lives if not for the assisted-suicide ban. Petitioners are the State of Washington and its Attorney General.
In January 1994, the respondents filed this action in the United States District Court for the Western District of Washington. They sought a declaration that Wash. Rev. Code § 9A.36.060 is unconstitutional on its face and an injunction against its enforcement. The District Court held that the statute was unconstitutional. A panel of the Court of Appeals for the Ninth Circuit reversed that decision, but the full court sitting en banc reversed the panel and affirmed the District Court. The Supreme Court granted certiorari to review the case.
Isabella Ingram and her husband sought contraceptives banned by state law. The court applied in aequo principles to protect marital privacy as an equitable interest beyond strict statutory text.
Griswold v. Connecticut381 U.S. 479 (1965)
Estelle Griswold served as Executive Director of the Planned Parenthood League of Connecticut. Dr. C. Lee Buxton served as the League's Medical Director and was a professor at Yale Medical School. Together they opened and operated a center in New Haven that was open from November 1 to November 10, 1961.
At the center they gave information, instruction, and medical advice to married persons as to the means of preventing conception. They examined the wife and prescribed the best contraceptive device or material for her use. Fees were usually charged, although some couples were serviced free.
The statutes involved were sections 53-32 and 54-196 of the General Statutes of Connecticut (1958 rev.). Section 53-32 made it a crime to use any drug, medicinal article or instrument for the purpose of preventing conception. Section 54-196 punished accessories as principals. The appellants were found guilty as accessories and fined $100 each.
The Appellate Division of the Circuit Court affirmed the convictions. The Supreme Court of Errors of Connecticut affirmed that judgment in State v. Griswold, 151 Conn. 544, 200 A. 2d 479. The United States Supreme Court noted probable jurisdiction.
The appellants asserted standing to raise the constitutional rights of the married persons with whom they had a professional relationship. A criminal conviction for serving married couples removes doubts about case or controversy. The rights of husband and wife would be diluted unless considered in a suit involving those who have this kind of confidential relation to them.
What does the Latin phrase in aequo signify in historical legal usage?
It refers to adjudication or treatment according to principles of equity rather than rigid common-law rules.
How does in aequo differ from ex aequo et bono?
In aequo simply means in equity. Ex aequo et bono refers to deciding a dispute according to what is fair and good, even without strict legal authority.
