I can't shake the feeling that if Hell truly had an "off" switch for Crowley's powers, it would have been flipped before Hastur and Ligur came for him.
And if not then (there could be some argument about whether their actions were officially sanctioned), they certainly would have cut him off before his trial to save themselves some potential trouble.
And if not then, at the very least, directly after he "survived" his holy bath, if only because anyone who escaped their clutches shouldn't be allowed to enjoy the benefits of hellish miracles to make their lives easier.
