A more thorough explanation:

Definition: Commissio rebellionis, also known as commission of rebellion, was an attaching process that allowed a layperson to arrest and bring a defendant to Chancery to enforce obedience to a writ of subpoena or decree. It was used when a person failed to appear in court after being ordered to do so, and was considered a rebellious act.

Example: If a person was ordered by the court to appear before it on a certain day, and failed to do so, a commission of rebellion could be issued against them. This commission would command certain persons to apprehend the person and bring them to court, as they were considered a rebel and contemner of the king's laws.

Explanation: The example illustrates how a commission of rebellion was used to enforce obedience to court orders and maintain the authority of the king's laws. It empowered laypersons to act as agents of the court and bring defendants to justice, even if they were not law enforcement officials. This helped to ensure that court orders were taken seriously and that those who disobeyed them were held accountable.
