Opinion of the Court
B
We see nothing in §363(m)’s limits that purports to “gover[n] a court’s adjudicatory capacity.” Henderson, 562 U. S., at 435.
Start with the text. Far from addressing “ ‘a court’s authority,’ ” or “ ‘refer[ring] in any way to the jurisdiction of the district courts,’ ” Fort Bend County, 587 U. S., at ___ (slip op., at 9), §363(m) takes as a given the exercise of judicial power over any authorization under §363(b) or §363(c) (hereinafter called “covered authorizations”).

Id., at 157–158. We found that the provision was nonjurisdictional, and thought it key that the provision expressly envisioned courts adjudicating some claims even absent registration, id., at 165, since it would have been “at least
