The Inquisitorial Squad
The Inquisitorial Squad was like the High Inquisitor's Prefects. They were, however, given the power to take away and add house points. These individuals were a handpicked group of students that were chosen by the High Inquisitor because of their support of the Ministry. They wore small silver badges with an "I" on it to show membership.

End of the High Inquisitor's Reign
Dolores Umbridge, the first and only Hogwarts High Inquisitor, was removed from her post following the Battle of the Department of Mysteries. Disputed facts are that she resigned from her positon due to rampaging centaurs in the Forbidden Forest.

Umbridge had been lured there, thinking a weapon had been built by Dumbledore's Army was there. Hermione Granger had been the one who came up with the plan, if only to save Harry Potter from Umbridge's Cruciatus Curse.

The Battle of the Dark Forest
"You filthy half-breeds! You have been given the right to stay here by Cornelius Fudge!"

- Dolores Umbridge

The Battle of the Dark Forest was not really a battle, but a fight. The centaur tribe that had ditched Firenze had found Harry Potter, Hermione Granger, and Umbridge walking through the forest. They imprisoned the trio, but Grawp helped Harry and Hermione escape.
