A more thorough explanation:

Ex assensu curiae is a Latin term that means "by or with the consent of the court."

When a lawyer files a motion in court, they may ask for permission to file it ex assensu curiae. This means that they are seeking the court's approval to file the motion.

Another example of using ex assensu curiae is when a judge asks for the parties' agreement on a particular issue. If both parties agree, the judge may enter an order ex assensu curiae.

These examples illustrate how ex assensu curiae is used to indicate that something is being done with the court's approval or consent.
