The United States bankruptcy law passed on July 1,1898, ends with the following provision: “ This act shall go into full force and effect upon its passage; provided, however, that no petition for voluntary bankruptcy shall be filed within one month of the passage thereof, and no petition for involuntary bankruptcy shall be filed within four months of the passage thereof. Proceedings commenced under State insolvency laws before the passage of this act shall not be affected by it.”
The question in this case is whether this act so far superseded the insolvency laws of this Commonwealth from the time of its *179passage as to deprive our courts of jurisdiction to entertain petitions for the commencement of insolvency proceedings filed after July 1, 1898. This depends upon the intention of Congress, as manifested by the language above quoted. Of the power of Congress to pass an act having this effect, there is no. doubt. Const. U. S. Art. 1, § 8, cl. 4. Griswold v. Pratt, 9 Met. 16. In re Klein, 1 How. 277, 280, 281. Sturges v. Crowninshield, 4 Wheat. 122, 192. Ogden v. Saunders, 12 Wheat. 213, 369. The language is materially different from that of the bankruptcy act of 1867, and from that of the earlier bankruptcy law of 1841. See U. S. St. March 2, 1867; Day v. Bardwell, 97 Mass. 246; Judd v. Ives, 4 Met. 401; Swan v. Littlefield, 4 Cush. 574. The argument that the change in question was intentional is almost irresistible. The act is to “ go into full force and effect upon its passage.” That is to say, the rights of all persons, in the particulars to which the act refers,
' are to be determined by the act from the time of its passage. Among these rights is the right to have insolvent estates settled in bankruptcy under the provisions of the act, including the rights to have acts of bankruptcy affecting the settlement of estates determined by it (§ 3), to have the rights of debtors to file voluntary petitions, and of creditors to file involuntary petitions determined by it (§ 4), and to have preferences and liens governed by the provisions of it (§§ 60 and 67). These various provisions affecting the rights and conduct of debtors and creditors are different from those previously existing in most of the States, and perhaps different from those found in the laws of any State, and they supersede all conflicting provisions. The only limitation upon the full and complete operation of the act upon its passage is that the right to begin proceedings is postponed one month in the case of voluntary petitions and four months in the case of involuntary petitions. Whenever the proceedings are commenced, the conduct of the parties after the passage of the act is to be tested by its requirements. The only saving clause affecting the jurisdiction of State courts provides for cases commenced in those courts before the passage of the act. The plain implication is that proceedings commenced in the State courts after the passage of the act are unauthorized. This is in accordance with the earlier language giving the statute full force and effect *180from tlie time of its passage, except that the filing of petitions is to be postponed for a short time.
We are of opinion that the language was chosen to make clear the purpose of Congress that the new system of bankruptcy should supersede all State laws in regard to insolvency from the date of the passage of the statute.
Demurrer overruled.
