Ng v. Attorney General, ___ F.3d ___, ___ n.4 (3d Cir. Feb. 7, 2006)(open question whether court of appeals owes Chevron deference to BIA streamlining decision merely rubber-stamping Immigration Judge's decision: "We have also previously questioned whether a BIA decision is entitled to deference when, as here, the BIA has affirmed without opinion the decision of the IJ pursuant to 8 C.F.R. 1003.1(e)(4). See Smriko v. Ashcroft, 387 F.3d 279, 289 n.6 ["[I]t would seem to be, at the very least, an open question as to whether an IJ's decision affirmed through the streamlining process would be entitled to Chevron deference . . . [D]eferring to the reasoning of an IJ from which the BIA would be free to depart in other cases would seem highly problematic."); cf. Singh, 383 F.3d at 152 ("[T]he BIA, by affirming without opinion, gave no considered and authoritative agency-wide interpretation of the statute . . . .")).
