A more thorough explanation:

Forum rei gestae

Forum rei gestae is a Latin term that refers to a court or forum where a particular act or thing was done. It is considered as a place of jurisdiction.

For instance, if a crime was committed in a particular location, the court or forum where the crime was committed is referred to as the forum rei gestae. Similarly, if a contract was signed in a particular place, the court or forum where the contract was signed is also referred to as the forum rei gestae.

These examples illustrate that the forum rei gestae is a place where a particular act or thing was done, and it is considered as a place of jurisdiction. It is where legal proceedings related to that act or thing can take place.
