The Supreme Court has determined that federal courts lack jurisdiction to consider challenges to the agency’s factual findings in connection with certain types of discretionary relief (such as adjustment of status). Perhaps worse, both the majority and the dissent recognize that this decision will likely foreclose any review of denials of adjustment of status (including those denied based on legal determinations, rather than factual findings) outside of the removal context.
As the dissent recognizes, this is a terrible decision that effectively leaves applicants with no way to correct agency errors.
