Can a Regional Council or a court constituted by it have any other powers besides those specified in this paragraph?
The context provided does not directly answer the question about whether a Regional Council or a court constituted by it can have any other powers besides those specified in this paragraph. However, it does state that "The Governor and, until assented to by him, shall have no effect." This suggests that there may be limitations on the powers of the Regional Council or a court constituted by it outside of what is explicitly mentioned in the context provided.
