I think it would actually be the book of Jwo Jeng that covers Inquisition procedure, since it was supposed to be the province of his order. The Schuelerites managed to 'absorb' the Order of Jwo Jeng several centuries ago, according to Himself, although exactly how isn't known [at least not to us]. IOW, the Order of Schueler was never intended to be judge, jury & executioner, nor to wield the power in the Church it does - I'm not sure if that role was originally supposed to belong to the Order of Langhorne, of if none of the orders was intended to hold primacy.
As to whether torture was explicitly included... my guess is that it was. However, like much of the rest of the Writ, we simply don't know what is said.

Clearly Chihiro would have had no moral objections to the use of torture, but I'd like to think he'd be smart enough to realize torture can be problematic if one is seeking the truth rather than a predetermined answer.
