In People v. LaFontaine 92 NY2d 470, 705 NE2d 663, 682 NYS2d 671 (1998), the suppression court upheld a federal arrest warrant executed in New York while invalidating a concomitantly executed New Jersey warrant. CPL 470.35 (1) precluded us from reaching the People's arguments concerning the New Jersey warrant because the suppression court's decision as to that warrant had no effect on the proceedings below--it neither "led to suppression or to the ultimate judgment of conviction" (see LaFontaine, 92 NY2d at 474). The Court noted that that posture represented an "exceptional procedural twist ... that blocked the sensible management of the case" (id. at 475).
