This is sort of a BRCS question, but I'll post it here because it also relates to 2E.

In 2E, if you were not the province ruler but held at least 1/2 the law of a province and the province was rebellious against it's ruler, you could divest the province away without occupation.

In BRCS, it appears that you must always militarily occupy a province in order to divest it to a new ruler. Is this correct?

If yes, why not permit a rebellious province in which someone else holds most of the law switch over to the other person?
