A lawsuit is a proceeding by one or more parties against one or more parties in a civil court of law. The archaic term "suit in law" is found in only a small number of laws still in effect today. The term "lawsuit" is used with respect to a civil action brought by a plaintiff who requests a legal remedy or equitable remedy from a court. The defendant is required to respond to the plaintiff's complaint or else risk default judgment. If the plaintiff is successful, judgment is entered in favor of the defendant. A variety of court orders may be issued in connection with or as part of the judgment to enforce a right, award damages or restitution, or impose a temporary or permanent injunction to prevent an act or compel an act. A declaratory judgment may be issued to prevent future legal disputes.
A trial court or court of first instance is a court having original jurisdiction, in which trials take place. Appeals from the decisions of trial courts are usually made by higher courts with the power of appellate review. Most appellate courts do not have the authority to hear testimony or take evidence, but instead rule solely on matters of law.
A Due Process Clause is found in both the Fifth and Fourteenth Amendments to the United States Constitution, which prohibit the deprivation of "life, liberty, or property" by the federal and state governments, respectively, without due process of law.
In United States constitutional law, incorporation is the doctrine by which portions of the Bill of Rights have been made applicable to the states. When the Bill of Rights was ratified, the courts held that its protections extended only to the actions of the federal government and that the Bill of Rights did not place limitations on the authority of the state and local governments. However, the post–Civil War era, beginning in 1865 with the Thirteenth Amendment, which declared the abolition of slavery, gave rise to the incorporation of other amendments, applying more rights to the states and people over time. Gradually, various portions of the Bill of Rights have been held to be applicable to state and local governments by incorporation via the Due Process Clause of the Fourteenth Amendment of 1868.
In the law of the United States, diversity jurisdiction is a form of subject-matter jurisdiction that gives United States federal courts the power to hear lawsuits that do not involve a federal question. For a federal court to have diversity jurisdiction over a lawsuit, two conditions must be met. First, there must be "diversity of citizenship" between the parties, meaning the plaintiffs must be citizens of different U.S. states than the defendants. Second, the lawsuit's "amount in controversy" must be more than $75,000. If a lawsuit does not meet these two conditions, federal courts will normally lack the jurisdiction to hear it unless it involves a federal question, and the lawsuit would need to be heard in state court instead.
Erie Railroad Co. v. Tompkins, 304 U.S. 64 (1938), was a landmark U.S. Supreme Court decision in which the Court held that the United States does not have a general 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 the modern law of diversity jurisdiction.
The Erie doctrine is a fundamental legal doctrine of civil procedure in the United States which mandates that a federal court called upon to resolve a dispute not directly implicating a federal question must apply state substantive law.
Sampson v. Channell, 110 F.2d 754, was a United States Court of Appeals decision interpreting the application of the Erie doctrine where diversity jurisdiction is invoked in a choice of law situation, where a court in one state may be called upon to apply the laws of another state.
United States v. Reynolds, 345 U.S. 1 (1953), is a landmark legal case decided in 1953, which saw the formal recognition of the state secrets privilege, a judicially recognized extension of presidential power. The US Supreme Court confirmed that "the privilege against revealing military secrets ... is well established in the law of evidence".
BMW of North America, Inc. v. Gore, 517 U.S. 559 (1996), was a United States Supreme Court case limiting punitive damages under the Due Process Clause of the Fourteenth Amendment.
In United States law, remittitur is a ruling by a judge lowering the amount of damages granted by a jury in a civil case. The term is sometimes used where a judgment exceeds the amount demanded by the prevailing party, or for a reduction in awarded damages even when the amount awarded did not exceed the amount demanded but is otherwise considered excessive. The term originally denoted a procedural device in English common law, although it has long fallen into disuse in England and other common law jurisdictions, and it has evolved in American use to serve a different function than it originally performed in England.
Byrd v. Blue Ridge Rural Electric Cooperative, Inc., 356 U.S. 525 (1958), decided on May 19, 1958, was a decision by the Supreme Court of the United States that refined the doctrine regarding in what instances courts were required to follow state law.
Guaranty Trust Co. v. York, 326 U.S. 99 (1945), was a United States Supreme Court case that described how federal courts were to follow state law. Justice Frankfurter delivered the majority opinion further refining the doctrine set forth in Erie Railroad Co. v. Tompkins.
Cooper Industries, Inc. v. Leatherman Tool Group, Inc., 532 U.S. 424 (2001), was a decision by the United States Supreme Court involving the standard of review that Federal Appeal Courts should use when examining punitive damages awards.
The Kano trovafloxacin trial litigation arose out of a clinical trial conducted by the pharmaceutical company Pfizer in 1996 in Kano, Nigeria, during an epidemic of meningococcal meningitis. To test its new antibiotic, trovafloxacin (Trovan), Pfizer gave 100 children trovafloxacin, while another 100 received the gold-standard anti-meningitis treatment, ceftriaxone, a cephalosporin antibiotic. Pfizer gave the children a substantially reduced dose of the ceftriaxone relative to that described on the US FDA-approved prescribing information. The allegation is that this was done to skew the test in favor of its own drug. Pfizer claimed that the dose used was sufficient even though a clinical trial performed by Médecins Sans Frontières recommends a dose of 50–100 mg/kg.
Sosa v. Alvarez-Machain, 542 U.S. 692 (2004), was a United States Supreme Court case involving the Alien Tort Statute and the Federal Tort Claims Act. Many ATS claims were filed after the Second Circuit ruling in Filártiga v. Peña-Irala created a new common law cause of action for torture under the ATS: "For purposes of civil liability, the torturer has become—like the pirate and slave trader before him—hostis humani generis, an enemy of all mankind." The Court in Sosa does not find there is a similar cause of action for arbitrary arrest and detention. They wrote that finding new common law causes of action based on international norms would require "a substantial element of discretionary judgment", and explain that the role of common law has changed since ATS was enacted meaning the Court will "look for legislative guidance before exercising innovative authority over substantive law".
The Double Jeopardy Clause of the Fifth Amendment to the United States Constitution provides: "[N]or shall any person be subject for the same offence to be twice put in jeopardy of life or limb..." The four essential protections included are prohibitions against, for the same offense:
Mt. Healthy City School District Board of Education v. Doyle, 429 U.S. 274 (1977), often shortened to Mt. Healthy v. Doyle, was a unanimous U.S. Supreme Court decision arising from a fired teacher's lawsuit against his former employer, the Mount Healthy City Schools. The Court considered three issues: whether federal-question jurisdiction existed in the case, whether the Eleventh Amendment barred federal lawsuits against school districts, and whether the First and Fourteenth Amendments prevented the district, as a government agency, from firing or otherwise disciplining an employee for constitutionally protected speech on a matter of public concern where the same action might have taken place for other, unprotected activities. Justice William Rehnquist wrote the opinion.
Evans v. Eaton, 20 U.S. 356 (1822), was a United States Supreme Court case in which the Court held, chiefly, that a patent on an improved machine must clearly describe how the machine differs from the prior art.
TXO Production Corp. v. Alliance Resources Corp., 509 U.S. 443 (1993), was a decision by the Supreme Court of the United States, which upheld the decision of the West Virginia state court awarding $19,000 in compensatory damages and $10 million in punitive damages to the plaintiff. Although multiple justices recognized that the punitive damages were 526 times the compensatory damages, the Court held a "general concern of reasonableness" should guide courts in determining constitutionally acceptable damages under the due process clause of the Fourteenth Amendment.
