Mandated.

In Deutsche Bank v. Burke, an appeal after a remand in a mortgage dispute, the magistrate judge “proceeded to defy the mandate and contravene the law of the case doctrine by concluding that our prior opinion was clearly erroneous and that failure to correct the error would result in manifest injustice.” Unsurprisingly, the Fifth Circuit reversed, reviewing the basic principles about those doctrines, and observing that “the conduct here is extraordinary conduct that would lead to chaos if routinely done.” No. 18-20026 (Sept. 5, 2018).
