Corwin signed several arrest warrants and transcribed a few of the hearings but scarcity of records from the 1692 events makes it impossible to determine Corwin's overall role in the trials as well as his attitude toward the acceptance in court of spectral evidence, the idea that actions seen in visions could be an indicator of witchcraft. The special court convicted nineteen of witchcraft and sentenced them to the gallows before it was disbanded in October 1692. The provincial court system was set up in January 1693, with the Superior Court of Judicature, the province's high court, hearing the remaining witchcraft cases.
