Opinion of the Court
More than a hundred days later, Mata (by then represented by new counsel) filed a motion with the Board to reopen his case. DHS opposed the motion, arguing in part that Mata had failed to fle it, as the INA requires, within 90 days of the Board's decision. Mata responded that the motion was “not time barred” because his first lawyer's “ineffective assistance” counted as an “exceptional circumstance[ ]” excusing his lateness.

It stated instead that “[I]n this circuit, an alien's request [to the BIA] for equitable tolling on the basis of ineffective assistance of counsel is construed as an invitation for the BIA to exercise its discretion to reopen the removal proceeding sua sponte.” Ibid. And circuit precedent held that courts have no jurisdiction to review the BIA's refusal to exercise its sua sponte power to
