A more thorough explanation:

RETORNA BREVIUM

Retorna brevium is a Latin term used in law that refers to the report made by a sheriff or other officer on the execution of a writ. It is the indorsement on a writ that indicates whether the writ has been executed or not.

For example, if a court issues a writ of execution to seize a debtor's property, the sheriff will execute the writ by seizing the property and then make a report on the writ, indicating that the writ has been executed. This report is known as the retorna brevium.

Another example is when a court issues a writ of habeas corpus to release a person who has been unlawfully detained. The sheriff or other officer will execute the writ by releasing the person and then make a report on the writ, indicating that the writ has been executed. This report is also known as the retorna brevium.

The examples illustrate how the retorna brevium is used in law to indicate the execution of a writ. The report made by the sheriff or other officer on the writ's execution is important because it informs the court whether the writ has been carried out or not. This helps the court to determine whether further action is necessary or not.
