A more thorough explanation:

Definition: Postulatio actionis is a Latin term used in Roman law. It refers to a request made to a magistrate who has the authority to hear a case, asking for permission to bring an action.

Example: If someone wants to sue another person in court, they must first make a postulatio actionis to the magistrate. This request outlines the details of the case and asks for permission to proceed with legal action.

Explanation: The example illustrates how postulatio actionis is used in Roman law. It shows that before a case can be heard in court, the plaintiff must first seek permission from the magistrate by making a formal request. This process helps to ensure that only legitimate cases are brought to court and that the legal system is not overwhelmed with frivolous lawsuits.
