The only substantial question presented is whether the proviso in section 17a (1) of the Bankruptcy Act, 11 U.S.C. § 35(a), preserves a pre-bankruptcy tax lien as to assets acquired after bankruptcy. The three district courts which have considered this question have answered it in the negative. In re Carlson, 292 F.Supp. 778 (C.D.Calif. 1968); In re Braund, 289 F.Supp. 604 (C.D.Calif. 1968); United States v. Sanabria (N.D.Ill., June 21, 1968) (Unreported) (Appeal pending in the Court of Appeals for the Seventh Circuit, No. 17,145). See also Marsh, Triumph or Tragedy? The Bankruptcy Amendments of 1966, 42 Wash.L.Rev. 681 (1967); Note, 14 Vill.L.Rev. 323, 326 (1969).
