A more thorough explanation:

FORUM ACTUS

Forum actus (for-uhm ak-tuhs). This is a Latin term that means "the place where an act was done."

One example of a forum actus is a courtroom. This is where legal proceedings take place, and where a judge or jury makes a decision based on the evidence presented.

Another example of a forum actus is a theater. This is where actors perform a play or musical, and where the audience watches and enjoys the show.

A forum actus is simply the location where an action or event takes place. It can be any place where something happens, whether it's a legal proceeding, a performance, or something else entirely. The examples given illustrate this definition by showing two very different types of forum actus: a courtroom and a theater. In both cases, something is happening that requires a specific location for it to take place.
