Legal Definitions - requisitory letter

A requisitory letter, also commonly known as a letter of request or letter rogatory, is a formal communication sent by a court in one country to a court in another country. Its primary purpose is to request judicial assistance in a legal proceeding that is taking place in the requesting court's jurisdiction.

This assistance typically involves tasks that the requesting court cannot perform itself because the necessary action, such as taking testimony from a witness, obtaining documents, or serving legal papers, must occur within the territory of the foreign court. It is a crucial instrument for international judicial cooperation, enabling legal processes to continue effectively even when evidence or parties are located across national borders.

• Example 1: Obtaining Witness Testimony Abroad

  Imagine a civil lawsuit in the United Kingdom where a key witness, whose testimony is essential for the case, has since moved and now resides permanently in Spain. The UK court cannot compel a Spanish resident to appear in a UK courtroom or to give a deposition within UK territory. In this situation, the UK court would issue a requisitory letter to a Spanish court, formally requesting that the Spanish court assist in obtaining the witness's testimony according to Spanish legal procedures. The letter would specify the questions to be asked or the scope of the testimony needed.

  This example illustrates a requisitory letter because the UK court is formally requesting judicial assistance from a foreign court (Spain) to perform an action (taking witness testimony) that is necessary for its own legal proceeding but falls outside its jurisdiction.

• Example 2: Gathering Evidence for a Criminal Investigation

  Consider a criminal investigation in Australia concerning cyber fraud, where crucial digital evidence, such as server logs and user data, is held by a technology company located in Ireland. Australian law enforcement and courts cannot directly compel an Irish company to release this information. To obtain this evidence, the Australian court would send a requisitory letter to an Irish court, asking for its help in compelling the Irish company to provide the necessary digital records, in compliance with Irish law.

  Here, the requisitory letter serves as the formal mechanism for the Australian court to seek cooperation from the Irish judicial system to gather evidence located within Ireland, which is essential for a criminal case in Australia.

• Example 3: Serving Legal Documents Internationally

  Suppose a company based in Canada is suing an individual who resides in Mexico. For the lawsuit to proceed fairly, the Mexican individual must be formally notified of the legal action against them by receiving the summons and complaint (known as "service of process"). Since the Canadian court cannot directly serve legal documents in Mexico, it would issue a requisitory letter to a Mexican court, requesting that the Mexican court arrange for the proper service of these legal documents on the individual in Mexico, following Mexican legal requirements.

  This scenario demonstrates a requisitory letter being used to facilitate the service of legal documents across international borders. The Canadian court relies on the Mexican court's assistance to ensure the defendant in Mexico is properly informed of the lawsuit, a fundamental step in any legal proceeding.
