Legal Definitions - non procedendo ad assisam

Non procedendo ad assisam is a Latin legal phrase that historically referred to a writ or order instructing a court or official not to proceed with a particular legal action, especially a trial or hearing (an "assize"). In essence, it was a command to halt or stay proceedings. While the specific term is archaic, the underlying concept of a higher authority directing a lower court to pause or stop a case remains relevant in modern legal systems through mechanisms like stays of proceedings or injunctions.

• Example 1 (Historical Land Dispute):

  Imagine a dispute over land ownership in medieval England. A local court, known as an assize, is preparing to hear the case. However, one of the parties appeals directly to the King's court, arguing that the local court lacks proper jurisdiction or that new evidence has emerged. The King's court might then issue a writ of "non procedendo ad assisam" to the local sheriff or judge, commanding them not to proceed with the land dispute trial until the King's court has reviewed the jurisdictional challenge or the new evidence.

  This illustrates the term by showing a higher authority (King's court) issuing an order to a lower court (assize) to halt its proceedings ("non procedendo") for a specific trial ("ad assisam") due to a pending issue that needs resolution elsewhere.

• Example 2 (Modern Analogy - Appellate Stay):

  Consider a complex civil lawsuit in a modern court where the trial judge has made a critical ruling on the admissibility of key evidence. One party believes this ruling is incorrect and immediately files an appeal to a higher court. To prevent the trial from moving forward based on what might be a flawed evidentiary decision, the appellate court could issue an order, functionally similar to a "non procedendo ad assisam," directing the trial court to stay or pause the trial proceedings until the appeal regarding the evidence ruling is heard and decided.

  Here, the appellate court's order to "stay" the trial serves the same purpose as the historical writ: it commands the lower court *not to proceed* with the trial ("non procedendo ad assisam") until a specific legal issue is resolved by a higher authority.

• Example 3 (Regulatory Review):

  Suppose a government regulatory agency is conducting an investigation into a company's environmental practices, and a related administrative tribunal is simultaneously preparing to hear a case against the same company for alleged violations. If the regulatory agency decides to undertake a comprehensive policy review that could significantly impact the tribunal's case, it might issue a directive to the tribunal to postpone or suspend its proceedings. This directive, though not using the Latin phrase, embodies the principle of "non procedendo ad assisam" by instructing the tribunal not to proceed with its hearing until the broader policy review is complete and its implications for the case are understood.

  This example demonstrates the concept in an administrative context, where a governing body instructs a tribunal *not to proceed* with a hearing ("non procedendo ad assisam") because a larger, related issue (policy review) needs to be addressed first, which could affect the outcome of the tribunal's case.
