Civil procedure in the context of "Civil law (common law)"

A plaintiff (Π in legal shorthand) is the party who initiates a lawsuit (also known as an action) before a court. By doing so, the plaintiff seeks a legal remedy. If this search is successful, the court will issue judgment in favor of the plaintiff and make the appropriate court order (e.g., an order for damages). Plaintiff is the term used in civil cases in most English-speaking jurisdictions, the notable exceptions being England and Wales, where a plaintiff has, since the introduction of the Civil Procedure Rules in 1999, been known as a "claimant" and Scotland, where the party has always been known as the "pursuer". In criminal cases, the prosecutor brings the case against the defendant, but the key complaining party is often called the "complainant".

In some jurisdictions, a lawsuit is commenced by filing a summons, claim form or a complaint. These documents are known as pleadings, that set forth the alleged wrongs committed by the defendant or defendants with a demand for relief. In other jurisdictions, the action is commenced by service of legal process by delivery of these documents on the defendant by a process server; they are only filed with the court subsequently with an affidavit from the process server that they had been given to the defendant according to the rules of civil procedure.

Procedural law, adjective law, in some jurisdictions referred to as remedial law, or rules of court, comprises the rules by which a court hears and determines what happens in civil, lawsuit, criminal or administrative proceedings. The rules are designed to ensure a fair and consistent application of due process (in the U.S.) or fundamental justice (in other common law countries) to all cases that come before a court.

Substantive law, which refers to the actual claim and defense whose validity is tested through the procedures of procedural law, is different from procedural law. In the context of procedural law, procedural rights may also refer not exhaustively to rights to information, access to justice, and right to counsel, rights to public participation, and right to confront accusers, as well as the basic presumption of innocence (meaning the prosecution regularly must meet the burden of proof, although different jurisdictions have various exceptions), with those rights encompassing general civil and political rights. In environmental law, these procedural rights have been reflected within the UNECE Convention on "Access to Information, Public Participation in Decision-making and Access to Justice in Environmental Matters" known as the Aarhus Convention (1998).

In court proceedings, a defendant is a person or object who is the party either accused of committing a crime in criminal prosecution or against whom some type of civil relief is being sought in a civil case.

Terminology varies from one jurisdiction to another. In Scots law, the terms "accused" or "panel" are used instead in criminal proceedings and "defender" in civil proceedings. Another term in use is "respondent".

A debtors' prison is a prison for people who are unable to pay debt. Until the mid-19th century, debtors' prisons (usually similar in form to locked workhouses) were a common way to deal with unpaid debt in Western Europe. Destitute people who were unable to pay a court-ordered judgment would be incarcerated in these prisons until they had worked off their debt via labour or secured outside funds to pay the balance. The product of their labour went towards both the costs of their incarceration and their accrued debt. Increasing access and lenience throughout the history of bankruptcy law have made prison terms for unaggravated indigence obsolete over most of the world.

Since the late 20th century, the term debtors' prison has also sometimes been applied by critics to criminal justice systems in which a court can sentence someone to prison over willfully unpaid criminal fees, usually following the order of a judge. For example, in some jurisdictions within the United States, people can be held in contempt of court and jailed after willful non-payment of child support, garnishments, confiscations, fines, or back taxes. Additionally, though properly served civil duties over private debts in nations such as the United States will merely result in a default judgment being rendered in absentia if the defendant willfully declines to appear by law, a substantial number of indigent debtors are legally incarcerated for the crime of failing to appear at civil debt proceedings as ordered by a judge. In this case, the crime is not indigence, but disobeying the judge's order to appear before the court. Critics argue that the "willful" terminology is subject to individual mens rea determination by a judge, rather than statute, and that since this presents the potential for judges to incarcerate legitimately indigent individuals, it amounts to a de facto "debtors' prison" system.

Sanctions, in law and legal definition, are penalties or other means of enforcement used to provide incentives for obedience with the law or other rules and regulations. Criminal sanctions can take the form of serious punishment, such as corporal or capital punishment, incarceration, or severe fines. Within the context of civil law, sanctions are usually monetary fines which are levied against a party to a lawsuit or to their attorney for violating rules of procedure, or for abusing the judicial process. The most severe sanction in a civil lawsuit is the involuntary dismissal, with prejudice, of a complaining party's cause of action, or of the responding party's answer. This has the effect of deciding the entire action against the sanctioned party without recourse, except to the degree that an appeal or trial de novo may be allowed because of reversible error. In international law, the United Nations Security Council may authorize international sanctions to maintain or restore international peace and security pursuant to article 41 of the United Nations Charter.

As a noun, the term is usually used in the plural form, even if it only refers to a single event: if a judge fines a party, it is not said that they imposed a sanction, but that they imposed sanctions.
