From the game's encyclopedia
At Limited Crown Authority or higher, Rulers can Revoke the Titles of their Vassals, but unless the Vassal is Imprisoned this is a risky proposition, for the Vassal may refuse and rise up in rebellion.
Title Revocation is considered Tyrannical unless the Vassal is guilty of a fairly severe Crime.
