LawLaw is a set of rules that are created and are enforceable by social or governmental institutions to regulate behavior, with its precise definition a matter of longstanding debate. It has been variously described as a science and as the art of justice. State-enforced laws can be made by a group legislature or by a single legislator, resulting in statutes; by the executive through decrees and regulations; or established by judges through precedent, usually in common law jurisdictions.
Trial courtA 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 (appellate courts). Most appellate courts do not have the authority to hear testimony or take evidence, but instead rule solely on matters of law. In the trial court, evidence and testimony are admitted under the rules of evidence established by applicable procedural law and determinations called findings of fact are made based on the evidence.
LawsuitA lawsuit is a proceeding by one or more parties (the plaintiff or claimant) against one or more parties (the defendant) 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 (a party who claims to have incurred loss as a result of a defendant's actions) 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.
Case lawCase law, also used interchangeably with common law, is law that is based on precedents, that is the judicial decisions from previous cases, rather than law based on constitutions, statutes, or regulations. Case law uses the detailed facts of a legal case that have been resolved by courts or similar tribunals. These past decisions are called "case law", or precedent. Stare decisis—a Latin phrase meaning "let the decision stand"—is the principle by which judges are bound to such past decisions, drawing on established judicial authority to formulate their positions.
Res judicataRes judicata (RJ) or res iudicata, also known as claim preclusion, is the Latin term for matter decided and refers to either of two concepts in both civil law and common law legal systems: a case in which there has been a final judgment and that is no longer subject to appeal; and the legal doctrine meant to bar (or preclude) relitigation of a claim between the same parties. In the case of res judicata, the matter cannot be raised again, either in the same court or in a different court.
Legal caseA legal case is in a general sense a dispute between opposing parties which may be resolved by a court, or by some equivalent legal process. A legal case is typically based on either civil or criminal law. In most legal cases, there are one or more accusers and one or more defendants. In some instances, a legal case may occur between parties that are not in opposition, but require a legal ruling to formally establish some legal fact, such as a divorce.
JuryA jury is a sworn body of people (jurors) convened to hear evidence and render an impartial verdict (a finding of fact on a question) officially submitted to them by a court, or to set a penalty or judgment. Juries developed in England during the Middle Ages and are a hallmark of the English common law system. As such, they are used by the United Kingdom, the United States, Canada, Ireland, Australia, and other countries whose legal systems were derived from the British Empire.
