The policy for licensing questions is the same as any other question.
If the question is on-topic here on Software Engineering, nothing happens.
If the question is off-topic here on Software Engineering, it gets closed or migrated. If there exists a site where it is suitable and the question is not crap, it's eligible for migration. We can not have a migration path to Open Source, since migration paths to beta sites are not permitted. We do not need a migration path to Law due to the low frequency of migrations. If you feel a question should be migrated to either site, please flag it for moderator attention.
Note that I do have a fast-delete policy for custom close reasons (writing/debugging code, career/education advice, legal advice or aid, find/recommend stuff). If it is not of sufficient quality to migrate, a question closed for one of these reasons should be deleted quickly. We have had plenty of problems with these types of questions.
