Appellant Naval Weapons Center Federal Credit Union (Credit Union), the judgment creditor, appeals from the order of the district court affirming the bankruptcy court’s *844 decision to set aside the constable’s sale of the appellees’ dwelling home. We reverse.
I. JURISDICTION
As a preliminary matter, we consider our jurisdiction over this appeal. At oral argument, we raised the issue whether a timely notice of appeal was filed from the judgment of the bankruptcy court “[sjince this court’s jurisdiction can only be based on a proper exercise of jurisdiction in the [district court]. . .. ”
Matter of Ramsey,
The judgment of the bankruptcy court was entered on February 8, 1978. The notice of appeal from the judgment of the bankruptcy court was filed on February 21, 1978. The notice of appeal was thus not filed within the ten days allowed under Bankruptcy Rule 802(a). However, we take notice that the tenth day fell on a Saturday, the next day was a Sunday, and the following Monday, the 20th, was Washington’s Birthday, a legal holiday. Under Rule 6(a) of the Federal Rules of Civil Procedure, when the last day of the period for filing falls on a Saturday, Sunday, or legal holiday, the period runs until the end of the next day which is not a Saturday, Sunday, or legal holiday. Therefore, we determine that the filing of the notice of appeal on the 21st of February, 1978, was timely and this court has jurisdiсtion over this appeal.
II. FACTS
The bankruptcy court found that the Credit Union had recovered a money judgment against the appellees which was entered on June 30, 1975. An abstract of the judgment was recorded by the County Recorder, County of Kern, on July 9, 1975. On November 10, 1975, a writ of execution was issued by the Superior Court of California and recorded by the County Recorder, County of Kern. The writ of execution was levied on the dwelling home of the аppellees on December 7, 1975. The appellees filed a declaration of homestead on December 12, 1975. On December 22, 1975, a notice of the constable’s sale was given. Subsequently, on January 12, 1976, the appellees filed for bankruptcy. The property was sold at the constable’s sale on January 16, 1976.
The bankruptcy court also found that the appellees resided at the home in question and were at аll relevant times insolvent. Further, the court found that the constable’s sale had been conducted without its permission.
The bankruptcy court ruled that the dwelling home exemption of section 690.-235 1 of the California Code of Civil Procedure was applicable to the appellees’ property. Thus no lien was created by the recordation of the abstract of judgment on July 9, 1975, as section 674 of the California Code of Civil Procеdure provided that a recorded judgment does not become a lien on exempt property. The court held that a lien was obtained on the property at the time of the levy of execution on December 7, 1975; however, the lien thus obtained was within four months of the filing for bankruptcy and was therefore void under 67(a)(1) of the Bankruptcy Act, 11 U.S.C. § 107(a)(1). Similarly, the court ruled that even if the appellees had subsequently lost their section 690.235 exemption because they had failed to file an affidavit of exemption under section 690.26 2 of the California Code of Civil Procedure, the only lien *845 obtained occurred on December 7, 1975. Since the lien was obtained within four months of the filing for bankruptcy, it was void under section 67(a)(1). In addition, the court ruled that the sale of the appellees’ property was void as it had taken place in violation of the automatic stay provisions of section 601 of the Rules of Bankruptсy Procedure. 3
III. DISCUSSION
Section 690.235 provided that a dwelling home in which a debtor resided shall be exempt from execution to the same extent as the debtor would be entitled to select as a homestead under section 1237, et seq., of the California Civil Code, the homestead exemption statute. It was intended that section 690.235 would provide the same protection accorded under section 1237, et seq. without the requirement of the рrior filing or recordation of the exemption.
In re Sanford,
The bankruptcy court ruled that section 690.235 was applicable to appellees’ property which had been the subjеct of the constable’s sale. In reaching its decision, the court determined that:
“. . . Section 690.235 made no substantive change in the law; it did not increase the amount of the exemption or change the character of the property exempted; it merely stated that henceforth a debtor would be entitled to his homestead exemption whether he filed a homestead or not. I do not believe it can be said that a сreditor has been deprived of a substantial or substantive right merely because his debtor is relieved of the necessity of filing a piece of paper in order to keep his home.”
Appellant argues that the court erred because it retroactively applied section 690.-235 to the present case. Appellant contends that section 690.235 cannot be retroactively applied in this situation without violating the сonstitutional prohibition against the impairment of contractual obligations as set forth in Article 1, Section 10, Clause 1 of the United States Constitution. 4 This issue arises as section 690.235 became effective on July 1, 1975, and the judgment lien in question resulted from a debt owed to the Credit Union by appellees on several outstanding loans which had been entered into prior to the enactment of section 690.235.
A. Contract Clause
1. California Decisions
Two different courts from the State of California have considered the question raised here and have reached opposite conclusions. In
Daylin Medical and Surgical Supply, Inc. v. Thomas,
*846
The district court of appeals, in
San Diego White Truck Co. v. Swift,
In bankruptcy actions, the federal courts decide the merits of state exemptions, but the validity of the claimed state exemption is controlled by the applicable state law.
In the Matter of Jackson,
2. The Applicable Law
The United States Supreme Court has recognized that “ ‘literalism in the construction of the contract clause . . . would make it destructive of the public interest by depriving the State of its prerogative of self-protection.’
W.B. Worthen Co. v. Thomas,
“If the Contract Clause is to retain any meaning at all, however, it must be understood to impose some limits upon the power of a State to abridge existing contractual relationships, even in the exercise of its otherwise legitimate police power.”
Allied Structural,
a. Impairment of Contractual Obligations
“The obligation of a contract is ‘the law which binds the parties to perform their agreement.’
Sturges v. Crowinshield,
Here, the exemption under section 690.-235 protected the dwelling home of the debtor to the same extent and in the same amount as the debtor would have been entitled to select through a declaration of homestead. However, differences between the two exemptions exist. The homestead exemption, which preceded the dwelling home exemption, could only be claimed if a declaration of homestead had been filed pri- or to the recordation of an abstract of judgment by a creditor. Where a homestead had not been previously declared, a judgment lien could attach and was enforceable as against that real property.
The exemption under section 690.235 required no prior filing. After a writ of execution had been levied upon his dwelling home, the debtor could then assert the dwelling home exemption to prevent execution of the writ. A recorded abstract of judgment which normally would become a judgment lien on real property which had not been protected under a homestead deсlaration could not attach to real property which qualified under section 690.235. 5
There is no question that appellees had not made a timely declaration of homestead. Under the law existing at the time the contractual relationship was entered into, a judgment lien would have attached upon the real property when the Credit Union recorded its abstract of judgment and the appellees’ propеrty would have thereafter been subject to execution. However, the retroactive application of section 690.235 exempted the appellees’ property from execution.
It is quite clear that had the homestead exemption not previously existed, the concept of the section 690.235 exemption would have been entirely new and its enactment and application would have presеnted a contract impairment situation identical to W. B. Worthen v. Thomas, Edwards v. Kearzey, and Medical Finance Ass’n v. Wood. Although the circumstances are not identical, we believe those precedents are nevertheless controlling. The net effect of section 690.235 was the creation of a new automatic exemption for dwelling homes where, previously, a timely declaration of homestead was required. Although the exemptions are similar, we believe that the differencеs and their results are significant. Under the circumstances of this case, we believe section 690.235 substantially impaired the pre-existing contractual obligations of the parties. We must therefore determine whether governmental interests justified the impairment.
b. Governmental Interests
A review of previous contract clause cases shows that in order to justify the
*848
impairment of contractual obligations, there must be a necessity for the legislation and the lеgislation must be reasonable under the circumstances.
See United States Trust Co. v. New Jersey,
Here, the California Legislature was concerned that a large majority of homeowners had not claimed the benefits of the homestead exemption, either through their ignorance of the law or their failure to satisfy the requirements for declaring a homestead.
San Diego White Truck,
B.Section 674
Through the relevant time period, section 674 provided that the recordation of an abstract of judgment in the county in which a judgment debtor’s real property was situated created a lien upon such real property unless such property was exempt from execution. Since we have determined that section 690.235 did not operate retroactively, appellees’ property was not exempt from execution when the Credit Union recorded the abstract of judgment on July 9, 1975. Thus, under section 674, a judgment lien attached to the property as of that date.
C. Section 67(a)(1) of the Bankruptcy Act
Section 67(a)(1) оf the Bankruptcy Act, 11 U.S.C. § 107(a)(1) provided that liens against property obtained within four months before the filing of a petition for bankruptcy shall be deemed null and void. After ruling that section 690.235 prevented the attachment of the judgment lien on July 9, 1975, the bankruptcy court determined that the Credit Union did obtain a lien on December 7, 1975, when a writ of execution was levied. However, the bankruptcy court held that since the lien was obtained within four months of the filing оf the petition for bankruptcy on January 12, 1976, the lien was void.
However, as we determined above, the lien was obtained when the abstract of judgment was recorded on July 9, 1975, which was more than four months prior to the filing of the bankruptcy petition. Thus the lien obtained was not invalid under section 67(a)(1).
D. Automatic Stay of Rule 601 of the Rules of Bankruptcy Procedure
The bankruptcy court also voided the constable’s sale of the appеllees’ property because it ruled that the sale was made in violation of the automatic stay provisions of the Rules of Bankruptcy Procedure Rule 601. Rule 601(a) provided that: *849 Thus, Rule 601 operated as an automatic stay of actions which affected the assets of the bankruptcy estate.
*848 “The filing of a petition [in bankruptcy] shall operate as a stay of any act or the commencement or continuatiоn of any court proceeding to enforce (1) a lien against property in the custody of the bankruptcy court, or (2) a lien against the property of the bankrupt obtained within four months before bankruptcy by attachment, judgment, levy, or other legal or equitable process or proceedings.”
*849
However, where a lien has been obtained more than four months before the filing of bankruptcy, judicial proceedings to enforce that lien may continue unabated unless the property remained in the custody of the bankrupt at the time the petition in bankruptcy was filed. Bankruptcy Rule 601, Advisory Committee’s Notes;
see Straton v. New,
Here, we believe the bankruptcy court had jurisdiction to determine when the lien on the appellees’ property was obtained and whether it was obtained within four months before bankruptcy. Having determined that the lien had been obtained within four months of bankruptcy, the court naturally concluded that the state court proceedings had not prevented the bankruptcy court from acquiring jurisdiction over the appel-lees’ property, and that the sale of the property was thus in violation of the Rule 601 automatic stay.
However, we have ruled that the Credit Union obtained a valid lien on the property on July 9, 1975, more than four months prior to the filing of bankruptcy. The state court proceedings to enforce the valid lien were instituted prior to bankruptcy; thus, the state court acquired jurisdiction over the appellees’ property. Therefore, we conclude that the foreclosure sale on January 16, 1976, was not made in violation of the stay provisions of Rule 601, as the stay did not apply to the property which was not under the bankruptcy court’s jurisdiction.
IV. CONCLUSION
Section 690.235 could not be applied retroactively to’prevent the attachment of the lien on appellees’ property on July 9, 1975. Thus the Credit Union obtained a lien on the property more than four months prior to the filing of bankruptcy.
The state court acquired jurisdiction over the property prior to the petition in bankruptcy. Thus the automatic stay provisions did not apply as the property was not under the jurisdiction of the bankruptcy court.
The judgment below is REVERSED.
Notes
. Section 690.235 stated in relevant part that:
A dwelling home in which the debtor or family of the debtor actually resides [shall be exempt from execution], to the same extent and in the same amount, except as otherwise provided in this section, as the debtor or spouse of the debtor would be entitled to select as a homestead provided that neither such debtor nor spouse has an existing declaration of homestead on any property in this state.
Section 690.235 was replaced by section 690.-31 of the California Code of Civil Procedure in 1977.
. The proсedures set forth in section 690.26 were replaced by section 690.50 of the California Code of Civil Procedure. Under the procedures, where a writ of execution had been levied upon property, the owner of the property had 20 days in which to deliver to the levying officer an affidavit claiming the exemption under section 690.235.
. This action took place prior to the enactment of the 1978 Bankruptcy Code. Therefore, all the bankruptcy provisions cited in this opinion will refer to provisions which were applicable under the prior law unless otherwise indicated.
. Article 1, Section 10, Clause 1 of the United States Constitution provides that:
“No State shall . . . pass any . . . Law impairing the obligations of Contracts .... ”
. Section 674 has since been amended to allow the attachment of judgment liens to dwelling homes where no homestead declaration had been made.
