A precedent is a principle or rule established in a previous legal case that is either binding on or persuasive without going to courts for a court or other tribunal when deciding subsequent cases with similar issues or facts. Common-law legal systems place great value on deciding cases according to consistent principled rules, so that similar facts will yield similar and predictable outcomes, and observance of precedent is the mechanism by which that goal is attained. The principle by which judges are bound to precedents is known as stare decisis. Common-law precedent is a third kind of law, on equal footing with statutory law and subordinate legislation in UK parlance – or regulatory law.
Justiciability concerns the limits upon legal issues over which a court can exercise its judicial authority. It includes, but is not limited to, the legal concept of standing, which is used to determine if the party bringing the suit is a party appropriate to establishing whether an actual adversarial issue exists. Essentially, justiciability seeks to address whether a court possesses the ability to provide adequate resolution of the dispute; where a court believes that it cannot offer such a final determination, the matter is not justiciable.
An abstention doctrine is any of several doctrines that a United States court may apply to refuse to hear a case if hearing the case would potentially intrude upon the powers of another court. Such doctrines are usually invoked where lawsuits involving the same issues are brought in two different court systems at the same time.
Erie Railroad Co. v. Tompkins, 304 U.S. 64 (1938), was a landmark U.S. Supreme Court decision in which the Court held that there is no general American federal common law and that U.S. federal courts must apply state law, not federal law, to lawsuits between parties from different states that do not involve federal questions. In reaching this holding, the Court overturned almost a century of federal civil procedure case law, and established the foundation of what remains the modern law of diversity jurisdiction as it applies to United States federal courts.
The federal judiciary of the United States is one of the three branches of the federal government of the United States organized under the United States Constitution and laws of the federal government. The U.S. federal judiciary consists primarily of the U.S. Supreme Court, the U.S. Courts of Appeals, and the U.S. District Courts. It also includes a variety of other lesser federal tribunals.
United States federal administrative law encompasses statutes, common law, and directives issued by the Office of Information and Regulatory Affairs in the Executive Office of the President, that together define the extent of powers and responsibilities held by administrative agencies of the United States government. The executive, legislative, and judicial branches of the U.S. federal government cannot always directly perform their constitutional responsibilities. Specialized powers are therefore delegated to an agency, board, or commission. These administrative governmental bodies oversee and monitor activities in complex areas, such as commercial aviation, medical device manufacturing, and securities markets.
District of Columbia Court of Appeals v. Feldman, 460 U.S. 462 (1983), was a case decided by the United States Supreme Court in which the Court enunciated a rule of civil procedure known as the Rooker-Feldman doctrine. The doctrine holds that lower United States federal courts may not sit in direct review of state court decisions.
Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc., 467 U.S. 837 (1984), was a landmark case in which the United States Supreme Court set forth the legal test for determining whether to grant deference to a government agency's interpretation of a statute which it administers. The decision articulated a doctrine now known as "Chevron deference". The doctrine consists of a two-part test applied by the court, when appropriate, that is highly deferential to government agencies: "whether the agency's answer is based on a permissible construction [emphasis added] of the statute", so long as Congress has not spoken directly to the precise issue at question.
Toilet Goods Association, Inc. v. Gardner, 387 U.S. 158 (1967), was a case heard before the United States Supreme Court. It held that judicial review of a regulation's validity was inappropriate because the controversy was not ripe for adjudication. Since it was not clear whether or not an inspection would be ordered and the reasons had not been given by the Commissioner to justify his order, no primary conduct was affected and so no irremediable adverse consequences flowed from requiring a later challenge to the regulation by a manufacturer, who refused to allow inspection.
Abbott Laboratories v. Gardner, 387 U.S. 136 (1967), was a case heard before the United States Supreme Court. Abbott Laboratories held that drug companies were not prohibited by the ripeness doctrine from challenging a U.S. Food and Drug Administration (FDA) regulation requiring a prescription drug's generic name to appear on all related printed materials. The government argued that the case was not ripe because the regulation had yet to be enforced. That argument failed as the Court found the issues to be fit for judicial resolution, and that the drug companies would experience substantial hardship if denied a pre-enforcement challenge to the statute. Prosecution for non-compliance was likely, civil and criminal penalties could be imposed, and the drug companies would suffer reputational damage if required to violate the regulation before challenging it in court.
Williamson County Regional Planning Commission v. Hamilton Bank of Johnson City, 473 U.S. 172 (1985), is a U.S. Supreme Court case that limited access to federal court for plaintiffs alleging uncompensated takings of private property under the Fifth Amendment. In June 2019, this case was overruled in part by the Court's decision in Knick v. Township of Scott, Pennsylvania.
In Pacific Gas & Electric Co. v. State Energy Resources Conservation & Development Commission, 461 U.S. 190 (1983), the United States Supreme Court held that a state statute regulating economic aspects of nuclear generating plants was not preempted by the federal Atomic Energy Act of 1954. The case provides a framework that has guided other cases involving preemption of federal authority.
In Constitutional law, the Last Resort Rule is a largely prudential rule which gives a federal court the power to avoid a constitutional issue in some circumstances. This rule dictates that, even if all other jurisdictional and justiciability obstacles are surmounted, federal courts still must avoid a constitutional issue if there is any other ground upon which to render a final judgment. The last resort rule can function as a distinct barrier to Constitutional avoidance. It is articulated by Justice Brandeis in Ashwander v. Tennessee Valley Authority.
Zobrest v. Catalina Foothills School District, 509 U.S. 1 (1993), was a case before the United States Supreme Court.
Ashwander v. Tennessee Valley Authority, 297 U.S. 288 (1936), was a United States Supreme Court case that provided the first elaboration of the doctrine of "Constitutional avoidance".
Constitutional avoidance is a legal doctrine in United States constitutional law that dictates that United States federal courts should refuse to rule on a constitutional issue if the case can be resolved without involving constitutionality. When a federal court is faced with a choice of ruling on a statutory, regulatory, or constitutional basis, the Supreme Court of the United States has instructed the lower court to decide the federal constitutional issue only as a last resort: "The Court will not pass upon a constitutional question although properly presented by the record, if there is also present some other ground upon which the case may be disposed of." Ashwander v. Tennessee Valley Authority, 297 U.S. 288, 347 (1936).
The Administrative Procedure Act (APA), Pub.L. 79–404, 60 Stat. 237, enacted June 11, 1946, is the United States federal statute that governs the way in which administrative agencies of the federal government of the United States may propose and establish regulations and grants U.S. federal courts oversight over all agency actions. According to Hickman & Pierce, it is one of the most important pieces of United States administrative law, and serves as a sort of "constitution" for U.S. administrative law.
United Gas Pipe Line Co. v. Ideal Cement Co., 369 U.S. 134 (1962), is a United States Supreme Court case which vacated a lower appellate court decision, holding that federal courts should abstain from ruling on the constitutionality of a state tax issue that state courts should determine.
Consular nonreviewability refers to the doctrine in immigration law in the United States where the visa decisions made by United States consular officers cannot be appealed in the United States judicial system. It is closely related to the plenary power doctrine that immunizes from judicial review the substantive immigration decisions of the United States Congress and the executive branch of the United States government.
Louisiana Power & Light Co. v. City of Thibodaux, 360 U.S. 25 (1959), was a case in which the Supreme Court created a new doctrine of abstention.
