Writ System
Quick Summary of Writ System

The common law utilised the writ system as a procedural method for commencing legal action. To initiate a lawsuit, a plaintiff would first need to obtain the appropriate original writ, such as a writ of trespass in the case of property infringement. The defendant would then be served with the writ and required to appear in court to defend themselves. Essentially, the writ system provided a means for plaintiffs to initiate legal proceedings under common law, with the specific type of writ obtained being dependent on the nature of the claim being made. The example of a writ of trespass serves as a clear illustration of how this system was utilised to pursue legal action against those who had trespassed on another’s property.

In the past, the writ system served as a means to initiate a legal case. To sue someone, the plaintiff had to obtain a specific document known as a writ. This document provided the court with information about the nature of the case and the parties involved, essentially serving as permission to commence legal proceedings. Various types of writs were utilised for different categories of cases.

Full Definition Of Writ System

The writ system forms a cornerstone of the British legal tradition, having evolved over centuries from its roots in medieval England. Originally, writs were formal written orders issued by the monarch, directing a person to perform or refrain from performing a specific act. Over time, they became integral to the administration of justice, facilitating the initiation of legal actions and the enforcement of court judgments. This legal overview explores the historical development, types, functions, and modern relevance of the writ system in British law.

Historical Development

The origins of the writ system can be traced back to the early medieval period. Initially, writs were simple mandates issued by the king or his officials. The Norman Conquest of 1066 significantly influenced the development of the writ system, introducing new administrative and legal practices from Normandy. The royal courts began to standardise the issuance of writs, gradually formalising the process.

By the 12th century, under the reign of Henry II, the use of writs became more systematic. The Assize of Clarendon (1166) and the Assize of Northampton (1176) established procedures for criminal and civil matters, significantly relying on writs to initiate legal proceedings. The establishment of the royal courts – the King’s Bench, Common Pleas, and Exchequer – further solidified the role of writs in the administration of justice.

Types of Writs

Writs can be broadly categorised into various types based on their purposes and functions. The principal categories include:

  1. Original Writs: These were used to commence a lawsuit. For instance, a writ of debt would initiate an action to recover money owed. Original writs were essential in summoning a defendant to court.
  2. Judicial Writs: Issued by the court during litigation, these writs directed parties to perform specific acts or ordered the execution of a judgment. Examples include writs of execution and writs of attachment.
  3. Prerogative Writs: These are extraordinary writs issued by the sovereign or higher courts to control lower courts or public authorities. Notable prerogative writs include habeas corpus, mandamus, prohibition, certiorari, and quo warranto.
  4. Writs of Assistance: These writs were used particularly in the context of customs and excise, granting officials the authority to search premises and seize goods.

Functions of Writs

The writ system served several critical functions in the medieval and early modern legal landscape:

  1. Initiating Legal Proceedings: Original writs were the primary method for commencing lawsuits. They provided a formal and standardised way to bring disputes before the courts.
  2. Ensuring Compliance with Court Orders: Judicial writs were crucial in enforcing court orders and judgments. They ensured that the parties complied with the court’s directives.
  3. Exercising Royal Authority: Prerogative writs underscored the monarch’s authority over lower courts and public officials. They were instrumental in maintaining the hierarchy and integrity of the judicial system.
  4. Facilitating Administrative Actions: Writs of assistance and other administrative writs empowered officials to perform duties such as collecting taxes and enforcing regulations.

Evolution and Modern Relevance

The writ system underwent significant changes with the advent of statutory reforms and procedural simplifications. The 19th century saw major reforms aimed at streamlining legal procedures and reducing reliance on the traditional writ system. The Common Law Procedure Act of 1852 and the Judicature Acts of 1873-75 played pivotal roles in modernising the legal process.

Despite these reforms, the concept of writs remains embedded in modern British law, particularly in the realm of judicial review and administrative law. Prerogative writs, now more commonly referred to as “orders,” continue to be crucial tools in the judicial oversight of public authorities. For instance:

  1. Habeas Corpus: This writ, often hailed as a fundamental safeguard of individual liberty, requires a person detained to be brought before a court to determine the legality of their detention.
  2. Mandamus: This order compels a public authority to perform a duty it is legally obligated to complete. It ensures that public bodies act within their statutory remit.
  3. Prohibition: Issued by a higher court, this writ prevents lower courts or tribunals from exceeding their jurisdiction.
  4. Certiorari: This order quashes decisions of lower courts or public bodies that are deemed to have acted outside their authority or committed an error of law.
  5. Quo Warranto: This writ challenges the legality of a person’s claim to a public office.

The Writ of Habeas Corpus

Among the prerogative writs, habeas corpus holds a distinguished place due to its profound impact on individual rights and liberties. Originating from the Latin phrase meaning “you shall have the body,” habeas corpus has evolved as a critical mechanism for protecting individuals against unlawful detention.

The significance of habeas corpus was highlighted during periods of political turmoil and attempts at arbitrary detention. The Habeas Corpus Act of 1679 and subsequent legislation fortified its application, ensuring that detainees could seek judicial review of their detention. In modern times, habeas corpus continues to serve as a vital check against executive overreach and unlawful imprisonment.

Mandamus, Prohibition, and Certiorari

The writs of mandamus, prohibition, and certiorari are integral to administrative law, providing mechanisms for judicial review of administrative actions.

  • Mandamus compels public authorities to fulfil their legal duties, thereby addressing instances where a public body fails to act as required by law.
  • Prohibition ensures that lower courts and tribunals do not exceed their jurisdiction, thus maintaining the proper scope of their authority.
  • Certiorari allows higher courts to review and quash decisions of lower courts or administrative bodies that have acted beyond their powers or made legal errors.

These writs underscore the principle of accountability, ensuring that public authorities act within the confines of the law and respect the rights of individuals.

The Writ of Quo Warranto

Quo warranto, translating to “by what authority,” is a writ used to challenge the legitimacy of a person’s claim to a public office. Historically, it was employed to prevent usurpation of public roles and ensure that officeholders were duly qualified and authorised. Although less common in contemporary practice, quo warranto remains a useful tool for maintaining the integrity of public office and preventing unlawful occupation.


The writ system, with its deep historical roots and evolving applications, remains a cornerstone of British legal tradition. From its medieval origins to its modern manifestations, writs have played a crucial role in ensuring justice, maintaining administrative accountability, and protecting individual rights. The transformation of writs into modern judicial orders reflects the adaptability of the legal system, preserving the core principles of fairness and legality while evolving to meet contemporary needs.

Despite the procedural reforms and statutory changes, the enduring relevance of writs in British law highlights their significance as instruments of justice. Whether in the form of habeas corpus safeguarding personal liberty or mandamus compelling public authorities to act lawfully, writs continue to be essential tools in the pursuit of justice and the rule of law.

The writ system’s legacy, therefore, is one of enduring influence and adaptability, encapsulating the dynamic nature of the British legal tradition and its commitment to upholding justice and accountability in an ever-changing world.
