I didn't know about that. Didnt they get a new monarch recently? Something... royal... happened recently.

IMO if she was the heir, then she's legit. A monarch is the property owner of the land and their ownership of the land goes back to before the nation sat upon the land. She would be within her rights to evict all of the occupants of her land - unless she or her ancestors traded away those rights at some point, which may have happened, idk. Property must be held legally immutable because its the basis for exchange.
