Complain of an Inquisitor
Under Article 28 of the Inquisitors’ Standards, any person may complain that an Imperial Inquisitor has exceeded their Commission, abused an extraordinary power, fabricated evidence, or acted for an improper purpose. The complaint is examined by the Provincial Minister of State for Justice, and where examining it through the Ministry would itself be conflicted, it goes to the Governor.
You need not give your name. You will be given a number; keep it, and you may ask after the complaint at Verify a Paper without naming yourself to anybody.
Read the Standards first if you wish. They set out what an Inquisitor may and may not do, and Article 17 lists what no Commission confers upon one — among other things: no power to try, sentence or punish; no power to depose a Jarl; no power to obtain anything by torture.
