OPINION

ON REMAND FROM THE COURT EN BANC

The Confederated Bands and Tribes of the Yakima Indian Nation (“Yakimas”), invoking federal jurisdiction under 28 U.S.C. § 1362, brought this suit challenging the statutory and constitutional validity of the State of Washington’s assumption of criminal and civil jurisdiction over the Yakimas’ reservation lands. The district court rejected the Yakimas’ statutory and constitutional contentions, in part relying upon Quinault Tribe of Indians v. Gallagher (9th Cir. 1966) 368 F.2d 655 (“Quinault II”). Our court sua sponte ordered this case en banc for the limited purpose of deciding whether to overrule that portion of Quinault II which states that PL-2801 authorized Washington’s statutory partial assumption of jurisdiction (R.C.W. § 37.12.010). The majority of the court adhered to Quinault II, upholding R.C.W. § 37.12.010 against statutory attack. (Confederated Bands and Tribes v. Washington (9th Cir. en banc 1977) 550 F.2d 443.) The en banc court remanded the case to the panel to determine the constitutional questions raised by the Yakimas.

The Washington statute 2 divides jurisdiction into two broad categories: (1) jurisdiction assumed with the consent of the affected tribes; (2) jurisdiction assumed without tribal consent. As to unconsenting tribes, Washington assumed jurisdiction to the fullest extent possible under PL — 280 in respect of fee land, but assumed jurisdiction as to non-fee lands only with respect to eight subject matter categories (compulsory school attendance, public assistance, domestic relations, mental illness, juvenile delinquency, adoption proceedings, dependent children, and operation of motor vehicles on public thoroughfares). The Yakimas’ reservation is a checkerboard of fee owned and non-fee owned land.

*1334The Yakimas challenge the constitutional validity of this statute on both due process and equal protection grounds. They contend that the eight categories of subject matter jurisdiction assumed are vague and impermissibly over- and underinclusive and that the statute, on its face and as applied, deprives them of equal protection. The impact of territorial checkerboarding and fragmentation of subject matter jurisdiction creates a host of classifications that present difficult equal protection problems.3 We need to grasp firmly only one of these constitutional nettles — the classification based on the status of title to the land upon which an alleged criminal offense occurs. Under R.C.W. § 37.12.010, a Yakima Indian living on a parcel of non-fee land who is the victim of a crime has no law enforcement protection from Washington, but a Yakima Indian living on the adjoining parcel of fee land who is the victim of the same crime has law enforcement protection from Washington. We hold that Washington’s partial4 assumption of jurisdiction based upon this land title classification cannot withstand the Yakimas’ equal protection attack, and we strike down Section 37.12.010.

Before we analyze the title-based classification, we dispose of some preliminary questions. The first is the impact upon the equal protection issue of the court’s en banc decision that Washington’s partial assumption scheme was authorized by PL-280. At the risk of restating the obvious, a determination that Congress permitted Washington to enact the partial assumption scheme of Section 37.12.010 is not a pronouncement that the authorized scheme is constitutional. The en banc court did not purport to reach any constitutional issue. It is elementary, of course, that Congress cannot authorize a state to violate the Equal Protection Clause, any more than a state, without any federal involvement, can violate the Equal Protection Clause. (Cf. Dandridge v. Williams (1970) 397 U.S. 471, 483, 90 S.Ct. 1153, 1161, 25 L.Ed.2d 491 (“Although a State may adopt a maximum grant system in allocating its fund available for AFDC payments without violating the [Social Security] Act, it may not, of course, impose a regime ... in violation of the Equal Protection Clause of the Fourteenth Amendment.”); Shapiro v. Thompson (1969) 394 U.S. 618, 641, 89 S.Ct. 1322, 1335, 22 L.Ed.2d 600 (“Congress may not authorize the States to violate the Equal Protection Clause.”).)

Second, we recognize that the concepts of fundamental rights and strict scrutiny are inapplicable to the title-based classification system that we are testing. No matter how desirable may be effective criminal law enforcement on the reservation, we do not believe that the Indians’ interest in that public service can be characterized as “fundamental.” (See, San Antonio Independent School District v. Rodriguez (1973) 411 U.S. 1, 29-39, 93 S.Ct. 1278, 36 L.Ed.2d 16.) Although Section 37.12.010 has racial implications because its impact is limited to Indian reservations, the classification based on fee and non-fee lands within reservations is not on its face racially discriminatory, and, as far as the record reveals, was not adopted to mask racial discrimination. Both Indians and non-Indi*1335ans live on both fee and non-fee land within the Yakima reservation. (Cf. Jefferson v. Hackney (1972) 406 U.S. 535, 92 S.Ct. 1724, 32 L.Ed.2d 285. See generally, United States Dep’t of Agriculture v. Moreno (1973) 413 U.S. 528, 93 S.Ct. 2821, 37 L.Ed.2d 782; Ely, “Legislative and Administrative Motivation in Constitutional Law,” 70 Yale L.J. 1205 (1970).)

Third, we need not here decide whether the Supreme Court continues to espouse the traditional two-tier equal protection approach,5 because Washington’s title-based classification fails to meet any formulation of the rational basis test. (See, e. g., Massachusetts Board of Retirement v. Murgia (1976) 427 U.S. 307, 96 S.Ct. 2562,49 L.Ed.2d 520; Reed v. Reed (1971) 404 U.S. 71, 75-76, 92 S.Ct. 251, 30 L.Ed.2d 225; McDonald v. Board of Election Commissioners (1969) 394 U.S. 802, 808-09, 89 S.Ct. 1404, 22 L.Ed.2d 739; McGowan v. Maryland (1961) 366 U.S. 420, 425-26, 81 S.Ct. 1101, 6 L.Ed.2d 393.) A statute according different treatment to similarly situated persons on the basis of a criterion wholly unrelated to the objective of the statute is a denial of equal protection.

The operative criterion of the criminal jurisdiction classification in issue is the status of title. The purpose of the statute, as advanced by the Washington Attorney General, in limiting criminal jurisdiction over non-fee lands to offenses within the eight enumerated subject areas6 is that these areas are ones “in which the state has the most fundamental concern for the welfare of those least able to care for themselves . . . .” (C.T. at 586.) Washington argued7 that jurisdiction was limited to areas of “fundamental and overriding” concern. It did not argue that any other purpose was intended to be served by this limited jurisdiction over criminal acts committed on reservations, and no other rationale leaps to our eyes.8 (See, Gunther, “The Supreme Court 1971 Term, Foreword: In Search of Evolving Doctrine on a Changing Court: A Model for a Newer Equal Protection” 86 Harv.L.Rev. 1, 20-21 (1972).)

We can detect no rational connection between the stated purpose and the distinction based on land title within the reservation. The state’s interest in enforcing criminal law is no less “fundamental” or “overriding” on non-fee lands than on fee lands. ■An overriding concern with and responsibility for public order necessarily embrace both, once the state undertakes to assume any jurisdiction over either. No showing has been or can be made that the happenstance of title holding is related in any way to the need by the land occupants for law enforcement. Moreover, no relationship has been suggested or shown between the *1336interest and the ability of the state to provide law enforcement and the fee — non-fee status of the land within the reservation. This checkerboard jurisdictional structure based on a selection by land title is the “very kind of arbitrary legislative choice forbidden by the Equal Protection Clause . . ..” (Reed v. Reed (1971) 404 U.S. 71, 76, 92 S.Ct. 251, 254, 30 L.Ed.2d 225.) Accordingly, the partial territorial assumption of criminal jurisdiction under R.C.W. § 37.12.010 is a denial of equal protection.

Can the invalidated portion of Section 37.12.010 be separated from the remainder of the statute, or does the whole statute fall?9 The Washington legislature could have severed these provisions, but we cannot do so. The statute contains no severability clause.10 We are unable to attribute to Washington a willingness to include more jurisdiction than it undertook partially to assume.11 When Washington chose to be expansive in assumption, it evidenced that intention. But in the statute under attack, it expressly limited its assumption to partial jurisdiction. We do not believe that Washington would have attempted to regulate such categories of jurisdiction as juvenile delinquency without criminal jurisdiction or the availability of criminal sanctions. Nor do we believe that Washington would have undertaken to regulate such subjects as “dependent children,” “adoption proceedings,” or “public assistance,” without regulating “juvenile delinquency.” Finally, without criminal jurisdiction over offenses on the reservation and with no civil jurisdiction over events on non-fee lands, we cannot assume that Washington would have created a checkerboard pattern of civil jurisdiction, accepting civil jurisdiction over fee lands only. In short, the remainder of the statute cannot be rescued by a simple excision; the whole statute must be rewritten, a task manifestly beyond our constitutional competence.

REVERSED.
