Before WRIGHT and GOODWIN, Circuit Judges, and EAST, District Judge.

The appellant, Andrew Kanter, sustained injuries in an automobile accident in March 1970. In March of the following year, he filed suit in state court and two weeks later petitioned for adjudication as a bankrupt. The trustee, appel-lee herein, asserted that the personal injury lawsuit was an asset of the bankrupt estate and sought a determination to that effect by the bankruptcy judge.

The bankruptcy judge found that among Kanter’s debts were substantial medical bills resulting from the accident which was the subject of the state court action. The judge concluded that title to the personal injury action vested in the trustee and this was affirmed by the district court. In Re Kanter, 345 F.Supp. 1151 (C.D.Cal.1972).

The question before the district court and before us is whether Cal.Code Civ. Pro. § 688.1(b) so frustrates the full effectiveness of sections 70, sub. a(5) and 70, sub. c of the Bankruptcy Act that it is rendered invalid by the Supremacy Clause, Art. VI, Cl. 2. The district court found that the California law was in conflict with the Bankruptcy Act and declared the state provision unconstitutional. We affirm.

In Carmona v. Robinson, 336 F.2d 518 (9th Cir. 1964), we held that the predecessor to § 688.1 permitted a trustee in bankruptcy to include a personal injury action of the bankrupt among the estate’s assets, pursuant to § 70, sub. a(5) of the Bankruptcy Act. Subsequent to Carmona , California amended its law in an attempt to deny this right to the trustee, adding subsection (b) to former § 688.1. The legislative sponsor of the amendment stated:

The estate of the bankrupt does not include property which is exempt under state law, §§ 6 and 70, sub. a, Holden v. Stratton, 198 U.S. 202 , 25 S.Ct. 656 , 49 L.Ed. 1018 (1905). State law controls as to the validity of a particular exemption claim, In Re Jackson, 472 F.2d 589, 590 (9th Cir. 1973), and the exemption statutes of California are to be applied with liberality, Love v. Menick, 341 F.2d 680, 682 (9th Cir. 1965).

California obviously has the right to amend its law to expand the classes of property which are exempt from the claims of creditors, seeking to give debtors a “new opportunity in life and a clear field for future effort,” one of the goals of the Bankruptcy Act, Lines v. Frederick, 400 U.S. 18, 19 , 91 S.Ct. 113 , 27 L.Ed.2d 124 (1970), citing Local

Loan v. Hunt, 292 U.S. 234, 244, 245 , 54 S.Ct. 695 , 78 L.Ed. 1230 (1934). Such an expanded exemption would, by operation of § 6 and § 7, sub. a or § 70, sub. a(5), remove the exempted property from the reach of the trustee in ■bankruptcy.

The district court approved the finding of the bankruptcy judge that § 688.1(b) is not an exemption statute, Kanter, supra 345 F.Supp. at 1155 . We agree. The Bankruptcy Act recognizes the exemptions provided by state law in an effort to assist the bankrupt in making a fresh start, to protect the expectations of creditors and debtors under state law, and to eliminate any inducement for creditors to seek involuntary bankruptcy petitions as a means of reaching assets unavailable to them in state courts because of exemption provisions.

However, in recognizing state exemptions Congress did not provide the states with a free hand to circumscribe the powers of the bankruptcy trustee. It merely sought to recognize the limitations imposed by state law on the ability of creditors to reach the assets of debtors. “[I]f such exempt property is not subject to levy and sale under those statutes, then it cannot be made to respond under the act of Congress.” Smalley v. Laugenour, 196 U.S. 93, 97 , 25 S.Ct. 216, 217 , 49 L.Ed. 400 (1905), Flickinger v. McGavick, 262 F.2d 593, 594 (9th Cir. 1958); 1A Collier on Bankrutcy U 6.-14 at 869.

Section 688.1 is not such a general exemption provision. It specifically permits judgment creditors to obtain a lien on a debtor’s cause of action, and only limits the power of an “assignee by op-eratio'n of law,” a term intended to reach the trustee in bankruptcy. Hence it cannot be an exemption provision within the meaning of §§ 6 and 70, sub. a.

Similarly § 688.1 falls within the proviso in § 70, sub. a(5) since it specifically subjects a debtor’s cause of action to judicial process.

The operative effect of § 688.1(b) limits the powers of the trustee under § 70, sub. c:

11 U.S.C. § 110 (c) (1970). It seeks also to prevent the vesting of the debtor’s cause of action in the estate through the operation of § 70, sub. a(5).

In Perez v. Campbell, 402 U.S. 637, 644 , 91 S.Ct. 1704, 1708 , 29 L.Ed.2d 233 (1971), the Court held in invalidating an Arizona statute which conflicted with the provisions of the Bankruptcy Act that:

The Supreme Court has held that “one of the prime purposes of the bankruptcy law has been to bring about a ratable distribution among creditors of a bankrupt’s assets; to protect the creditors from one another.” Young v. Hig-bee Co., 324 U.S. 204, 210 , 65 S.Ct. 594, 597 , 89 L.Ed. 890 (1945); Hassen v. Jonas, 373 F.2d 880 (9th Cir. 1967). To this end, “The main thrust of § 70(a)(5) is to secure for creditors everything of value the bankrupt may possess in alienable or leviable form when he files his petition.” Lines v. Frederick, 400 U.S. 18, 19 , 91 S.Ct. 113 (1970), citing Segal v. Rochelle, 382 U.S. 375, 379 , 86 S.Ct. 511 , 15 L.Ed.2d 428 (1966).

There has been no state court opini-nion construing § 688.1(b). However, its intent seems clear in light of the statement of its legislative sponsor, supra. Moreover, the district court has construed the statute unequivocally to apply to the trustee and to limit his powers, 345 F.Supp. at 1156 . We have held that “a district judge’s interpretation of the law of the state where he sits will not be overturned unless clearly wrong, particularly if the highest state court has not passed on the matter.” Douglas v. Beneficial Finance Co. of Anchorage, 469 F.2d 453, 455 (9th Cir. 1972).

Section 688.1(b) thus “stands as an obstacle to the accomplishment and execution of the full purposes and objectives of Congress.” Hines v. Davidowitz, 312 U.S. 52, 67 , 61 S.Ct. 399, 404 , 85 L.Ed. 581 (1941), since it would operate to deny to the trustee assets which could ordinarily be reached in satisfying the claims of general creditors. Subsection (b) revives the race to the courthouse by creditors seeking to avoid the threat of having both their claims discharged and the assets necessary to satisfy them denied to the trustee. As the Court noted in Perez, supra at 652 , 91 S.Ct. at 1712, “any state legislation which frustrates the full effectiveness of federal law is rendered invalid by the Supremacy Clause.”

Since we decide this case on the basis of the Supremacy Clause, we need not consider whether § 688.1(b) is also infirm as a violation of the Equal Protection Clause of the 14th Amendment.

The decision of the district court is affirmed.
