What does Hale denounce at the end of Act III?

Hale denounces the court proceedings.

Explanation:

Reverend Hale quits the court and leaves Salem at the end of Act Three because his conscience will not permit him to participate in these trials. He has come to understand that the court is corrupt, that the girls are lying, and that innocent people are being convicted of witchcraft, a crime they have not committed, and condemned to hang.
