Landmark court decisions, in present-day common law legal systems, establish precedents that determine a significant new legal principle or concept, or otherwise substantially affect the interpretation of existing law. "Leading case" is commonly used in the United Kingdom and other Commonwealth jurisdictions instead of "landmark case" as used in the United States.
Respondeat superior is a doctrine that a party is responsible for acts of their agents. For example, in the United States, there are circumstances when an employer is liable for acts of employees performed within the course of their employment. This rule is also called the master-servant rule, recognized in both common law and civil law jurisdictions.
Though the actual definitions vary between jurisdictions, in general, a direct tax is a tax imposed upon a person or property as distinct from a tax imposed upon a transaction, which is described as an indirect tax. The term may be used in economic and political analyses, but does not itself have any legal implications. However, in the United States, the term has special constitutional significance because of a provision in the U.S. Constitution that any direct taxes imposed by the national government be apportioned among the states on the basis of population. In the European Union direct taxation remains the sole responsibility of member states.
In tort law, a duty of care is a legal obligation which is imposed on an individual requiring adherence to a standard of reasonable care while performing any acts that could foreseeably harm others. It is the first element that must be established to proceed with an action in negligence. The claimant must be able to show a duty of care imposed by law which the defendant has breached. In turn, breaching a duty may subject an individual to liability. The duty of care may be imposed by operation of law between individuals who have no current direct relationship but eventually become related in some manner, as defined by common law.
International Shoe Co. v. Washington, 326 U.S. 310 (1945), was a landmark decision of the Supreme Court of the United States in which the Court held that a party, particularly a corporation, may be subject to the jurisdiction of a state court if it has "minimum contacts" with that state. The ruling has important consequences for corporations involved in interstate commerce, their payments to state unemployment compensation funds, limits on the power of states imposed by the Due Process Clause of the Fourteenth Amendment, the sufficiency of service of process, and, especially, personal jurisdiction.
Secondary liability, or indirect infringement, arises when a party materially contributes to, facilitates, induces, or is otherwise responsible for directly infringing acts carried out by another party. The US has statutorily codified secondary liability rules for trademarks and patents, but for matters relating to copyright, this has solely been a product of case law developments. In other words, courts, rather than Congress, have been the primary developers of theories and policies concerning secondary liability.
Lennard's Carrying Co Ltd v Asiatic Petroleum Co Ltd [1915] AC 705 is a famous decision by the House of Lords on the ability to impose liability upon a corporation. The decision expands upon the earlier decision in Salomon v Salomon & Co. [1897] AC 22 and first introduced the "alter ego" theory of corporate liability.
The legal principle of vicarious liability applies to hold one person liable for the actions of another when engaged in some form of joint or collective activity.
Flint v. Stone Tracy Co., 220 U.S. 107 (1911), was a United States Supreme Court case in which a taxpayer challenged the validity of a federal income tax on corporations. The privilege of incorporation is a state function, and the challengers argued that only the states should tax corporations. The Court ruled that the privilege of operating in corporate form is valuable and justifies imposition of a federal income tax:
Negligent entrustment is a cause of action in tort law that arises where one party is held liable for negligence because they negligently provided another party with a dangerous instrumentality, and the entrusted party caused injury to a third party with that instrumentality. The cause of action most frequently arises where one person allows another to drive their automobile.
Wilmington Star Mining Co. v. Fulton, 205 U.S. 60 (1907), was a case concerning whether it is an appropriate exercise of the police power of the state to regulate the use of mining properties, and that mine owners are not deprived of their property, privileges, or immunities without due process of law, or denied the equal protection of the laws, by the Illinois Mining Statute of 1899, which requires the employment of licensed mine managers and mine examiners and imposes upon the mine owners liability for the willful failure of the manager and examiner to furnish a reasonably safe place for the workmen.
Religious Technology Center v. Netcom On-Line Communication Services, Inc., 907 F. Supp. 1361, is a U.S. district court case about whether the operator of a computer bulletin board service ("BBS") and Internet access provider that allows that BBS to reach the Internet should be liable for copyright infringement committed by a subscriber of the BBS. The plaintiff Religious Technology Center ("RTC") argued that defendant Netcom was directly, contributorily, and vicariously liable for copyright infringement. Netcom moved for summary judgment, disputing RTC's claims and raising a First Amendment argument and a fair use defense. The district court of the Northern District of California concluded that RTC's claims of direct and vicarious infringement failed, but genuine issues of fact precluded summary judgment on contributory liability and fair use.
Bazley v Curry, [1999] 2 SCR 534 is a Supreme Court of Canada decision on the topic of vicarious liability where the Court held that a non-profit organization may be held vicariously liable in tort law for sexual misconduct by one of its employees. The decision has widely influenced jurisprudence on vicarious liability outside of Canada.
United States v. White Mountain Apache Tribe, 537 U.S. 465 (2003), was a case in which the Supreme Court of the United States held in a 5–4 decision that when the federal government used land or property held in trust for an Indian tribe, it had the duty to maintain that land or property and was liable for any damages for a breach of that duty. In the 1870s, the White Mountain Apache Tribe was placed on a reservation in Arizona. The case involved Fort Apache, a collection of buildings on the reservation which were transferred to the tribe by the United States Congress in 1960.
United States v. Behrman, 258 U.S. 280 (1922), was a United States Supreme Court case in which the Court held that a violation of the Harrison Narcotics Act did not require a mens rea element and was thus a strict liability crime.
Wilkie v. Robbins, 551 U.S. 537 (2007), was a United States Supreme Court case that concerned the scope of qualified immunity for government officials working in the Bureau of Land Management (BLM). Specifically, the Supreme Court held that BLM employees could not be liable for an alleged retaliation claim against Robbins, a farm owner, because other avenues for relief were available. Though these workers may have been tough in negotiations with Robbins over access over his land, none of that rose to the level of a constitutional violation.
Texas Dept. of Housing and Community Affairs v. Inclusive Communities Project, Inc., 576 U.S. ___ (2015), was a United States Supreme Court case in which the Court analyzed whether disparate impact claims are cognizable under the Fair Housing Act. In Justice Anthony Kennedy's majority opinion, the Court held that Congress specifically intended to include disparate impact claims in the Fair Housing Act, but that such claims require a plaintiff to prove it is the defendant's policies that cause a disparity.
Contributory copyright infringement is a way of imposing secondary liability for infringement of a copyright. It is a means by which a person may be held liable for copyright infringement even though he or she did not directly engage in the infringing activity. In the United States, the Copyright Act does not itself impose liability for contributory infringement expressly. It is one of the two forms of secondary liability apart from 'vicarious liability'. Contributory infringement is understood to be a form of infringement in which a person is not directly violating a copyright but, induces or authorises another person to directly infringe the copyright.
