The Expunging Group, also known as the hr'Kash'te, which was a body within the Vulcan government.

It was one of three legislative bodies which handled planetary legislation which existed only to veto or remove laws. Furthermore, it was also known that it was the easiest to drive a change through as expunction required one fourth of the body's two thousand six members in order to remove a law.
