At some other SE sites, legal and business questions are explicitly off-topic. I just checked the help center and I didn't see anything about that.
Are questions about copyrights, for example, on-topic here?
As you can see from the
copyright tag, there are a number of questions about that subject.
It is important to note that you should not seek, and should not trust, legal advice here - this is a community of Movie and TV enthusiasts, not a legal team. If the question is particularly technical from a law standpoint its probably not the best place to ask it.
However if the question is broadly applicable to Movies and TV then its likely to be on-topic, especially if its on broad legal principles in Movie and TV production rather than something that is very specific to a particular territory.
