Cardozo-Tlaseca v. Gonzales, 460 F.3d 1102 (9th Cir. Aug. 21, 2006) (8 C.F.R. 1003.2, providing that motion to reopen removal proceedings could not be made subsequent to removal, did not preclude BIA from ruling on motion to reopen after conviction that formed the a key part of the basis of the removal order had been vacated; it was not necessary that the conviction be the sole reason for removal).
