Oral argument in Buarfa v. Mayorkas over whether revocations of visa petitions after a sham-marriage finding are discretionary (and therefore beyond judicial review) or nondiscretionary (and reviewable). Counsel for the petitioner argued revocations are nondiscretionary under 11 54 c and therefore reviewable; government counsel argued revocations fall under 11 55 and 12 52 bars review. The Court heard extended questioning and submitted the case.
