Legal Definitions - lex ordinandi

The legal term lex ordinandi refers to the procedural laws of the court where a legal case is being heard. Essentially, it dictates how a lawsuit is conducted, rather than determining the underlying legal rights or obligations of the parties involved. These procedural rules govern aspects such as how evidence is presented, deadlines for filing documents, the process of jury selection, and other operational aspects of the court.

It is a fundamental principle in legal systems that the court hearing a case will apply its own procedural rules, even if the substantive law (the law that determines the rights and wrongs of the dispute) of another jurisdiction might apply to the core issues of the case. This ensures consistency and fairness in the judicial process within that specific court.

• Example 1: Rules of Evidence

  Imagine a car accident occurs in Florida, but one of the drivers involved decides to sue the other driver in a Georgia state court. While the Georgia court might apply Florida's traffic laws to determine who was at fault (the substantive law), it will apply Georgia's rules of evidence regarding what testimony is admissible, how expert witnesses can be presented, or what documents can be shown to the jury. This is because the Georgia court follows its own lex ordinandi for procedural matters.

• Example 2: Statute of Limitations

  Consider a contract dispute between a company based in Canada and a company based in Mexico. The contract specifies that it is governed by Canadian law. However, if the Mexican company decides to file a lawsuit in a Mexican court, that court will apply Mexico's statute of limitations (the legal deadline for bringing a claim) to determine if the lawsuit was filed on time. Even though Canadian law dictates the terms of the contract, the Mexican court's own procedural rule regarding the filing deadline (its lex ordinandi) will prevail.

• Example 3: Discovery Procedures

  Suppose a product liability case is filed in a federal court in New York, involving a product manufactured in California and sold nationwide. The lawsuit alleges injuries sustained by a consumer in Texas. The federal court in New York will apply the Federal Rules of Civil Procedure and its own local rules concerning the discovery process (how parties exchange information and evidence before trial), such as the number of interrogatories allowed or the procedures for depositions. These procedural rules are part of the New York court's lex ordinandi, regardless of where the product was made or where the injury occurred.
