Defendant, or contestee, a registered Republican, and plaintiff, or contestant, a registered Democrat, filed and qualified as candidates, each for both parties, at the June, 1950, primary election for the office of member of the State *593 Assembly, 64th District. Defendant was nominated on both tickets at that election.
The Elections Code provides that any candidate at a primary election may contest the right of another candidate to nomination to the same office by filing in the superior court an affidavit alleging various grounds including ineligibility to the office in dispute. (Elec. Code, §§ 8600, 8603.) Issue may be joined by the other candidate (Id., § 8623) and the matter heard by the court and decision rendered (Id., §§ 8624-8628). Either party may appeal to the District Court of Appeal within 10 days after judgment below and that court must decide the case within 10 days after the appeal is perfected. (Id., § 8629.)
Pursuant to those provisions, plaintiff commenced a proceeding contesting defendant’s election at the primary on the ground that he failed to meet the requirement that: ‘ ‘. . . no person shall be a member of the senate or assembly who has not been a citizen and inhabitant of the state three years, and of the district for which he shall be chosen one year, next before his election." (Cal. Const., art. IV, §4.) The trial court decided in defendant’s favor and plaintiff appeals asserting in chief that the evidence is insufficient to establish that defendant was a “citizen and inhabitant” of the state for three years next before his election as required by section 4 of article IV of the California Constitution, supra.
While defendant contends that the judgment is amply supported by the evidence, he asserts that the trial court lacked jurisdiction to entertain the proceedings. In support of the latter position he relies upon the constitutional provision that: “Each house (of the Legislature) shall . . . judge of the qualifications, elections, and returns of its members." (Cal. Const., art. IV, § 7.) It is claimed that the Assembly, to the exclusion of the courts, is the arbiter and forum for determining whether its members are eligible for the office. The first case touching precisely upon this issue was
Allen
v.
Lelande,
In the instant case we have no question of a conflict between a statutory grant of jurisdiction to a local legislative body and a constitutional provision investing power in the courts. All provisions concerned here are in the Constitution and we think that section 7 of article IV,
supra,
confers exclusive jurisdiction on the Legislature to judge the qualifications and elections of its members. The powers of the government of the state are divided into the legislative, executive and judicial, and neither shall exercise the powers of the other
“except
as in this constitution expressly directed or permitted.” (Cal. Const., art. Ill, § 1.) And there is expressly
*595
vested in the Legislature, the power to judge the matters here involved (Cal. Const., art. IV, § 7,
supra),
a power which is judicial in character.
(Barry
v.
United States,
It is urged, however, that the constitutional power conferred on the Assembly over elections and qualifications of its members (Cal. Const., art. IV, § 7) does not extend to or include primary elections. It has been so held.

“The proceedings up to and including the issuance of the *596 certificate of election are wholly within the control of Congress. It was formerly held that primaries were not a part of the election process but that is no longer the established law.

“It was further held that when as in the Allwright Case the primary became a part of the machinery for choosing officials, state and federal, the same tests to determine the character of discrimination or abridgment should be applied to the primary as are applied to the general election.
“The Court overruled
Grovey
v.
Townsend,
1935,
‘ ‘ There can be no doubt that under the laws of the State of Wisconsin the primary election law is an integral part of the election process. No person can become a candidate of a political party in Wisconsin unless he can be a candidate for nomination by that party at a primary election. . . .
“Under United States v. Classic, supra, and Smith v. All-wright, supra, the same rules of law are applicable to a primary for the nomination for United States senator that are applicable to an election for United States senator.
“It is well established that under the provisions of Art. I, see. 5, courts have no jurisdiction to judge of the returns and elections of United States senators. . . .
“What the relator asks the Court to do is to hold that Mr. McCarthy is disqualified to be a candidate for the nomination by the Republican Party for the office of Senator of the United States by virtue of the provisions of sec. 10. The process of nomination under Wisconsin law is an integral part of the election process and is therefore, as has already been stated, wholly within the jurisdiction of the United States Senate. If Mr. McCarthy under Wisconsin law cannot be a candidate *597 for nomination at the primary, he can never be a candidate at the election of any political party. He is therefore disqualified to take the first step if the argument of the relator is sound. His right to be a candidate at the election would be a barren right. ’ ’
By analogy the jurisdiction to judge qualifications and elections of assemblymen lies exclusively with the Assembly and it cannot delegate that duty and it cannot achieve that result indirectly by authorizing the courts to decide contests after primary elections. As in Wisconsin, primary elections in this state are an integral part of the election process. (See
Communist Party
v.
Peek,
It is true that comprehensive powers are given to the Legislature with regard to primary elections by the Constitution as follows: “The Legislature shall have the power to enact laws relative to the election of delegates to conventions of political parties; and the Legislature shall enact laws providing for the direct nomination of candidates for public office, by electors, political parties, or organizations of electors without conventions, at elections to be known and designated as primary elections; also to determine the tests and conditions upon which electors, political parties, or organizations of electors may participate in any such primary election. It shall also be lawful for the Legislature to prescribe that any such primary election shall be mandatory and obligatory.” (Cal. Const., art. II, § 2½.) That power is not unlimited. (Communist Party v. Peek, supra.) We see nothing in it that purports to strip or relieve the Assembly or Senate of their duty and obligation to judge the qualifications, elections, and returns of their members. The anomalous results that would follow if a court could make a binding determination under section 8600 of the Elections Code are apparent. If the trial court gave its judgment, either favorable or unfavorable, to the candidate after the primary election but nevertheless the candidate at the ensuing election received the majority of the votes cast, there can be little doubt that he could present his credentials to the legislative house to which he was elected and that body would be required to pass upon any claimed defect in his selection, regardless of the conclusion reached by the court. Such could easily happen as it has in the instant case. The trial court judgment was favorable to defendant and it was affirmed on appeal by the District Court of Appeal *598 in September. But a hearing by this court was granted and in the meantime his name was on the ballot at the November election and he received a majority of the votes. For this court to rule upon the question would be futile, for the binding and conclusive decision rests with the Assembly. If the Legislature may, by authorizing court review of primary election contests, prevent a candidate from being on the ballot at the ensuing election for various defects as to the elections or qualifications, it would, in many situations, achieve indirectly what it could not do directly, that is, delegate to the courts its prerogatives under section 7 of article IV of the California Constitution.
It may be that in some senses a primary election is not an election (see
McClintock
v.
Abel,
Heney
v.
Jordan, supra, Norcop
v.
Jordan,
*599 The result reached makes it unnecessary to decide whether the evidence is sufficient to sustain the finding that defendant is eligible for the office of member of the state Assembly. The court had no jurisdiction to entertain the proceeding.
The judgment is reversed and the trial court directed to dismiss the proceeding.
Gibson, C. J., Shenk, J., Traynor, J., Schauer, J., and Spence, J., concurred.
Edmonds, J., concurred in the judgment.
