The Morag Tong is an unusual organization, in that it is a legal assassins guild. Located only in the Dunmer province of Morrowind, "members" of the Morag Tong are in possession of what is quite literally a license to kill; however, this license is not without its restrictions. Essentially, you must be given a charter that designates a specific individual the assassin is meant to kill. The assassin is permitted to kill no other individual, unless the order specifies an additional individual. Should law enforcers attempt to reprimand you after the deed has been committed, or should they try to intervene during the act, showing them the signed charter will discourage any further inquiry.
