Cal. Elec. Code § 20007
No candidate or committee in his or her behalf shall represent in connection with an election campaign, either orally or in campaign material, that the candidate has the support of a committee or organization that includes as part of its name the name or any variation upon the name of a qualified political party with which the candidate is not affiliated, together with the words "county committee," "central committee," "county," or any other term that might tend to mislead the voters into believing that the candidate has the support of that party's county central committee or state central committee, when that is not the case.
This section shall not be construed to prevent a candidate or committee from representing that the candidate has the support of a committee or group of voters affiliated with another political party, which committee or group is identified by the name of that party, where the name of the committee or group also includes the name of the candidate.
Any member of a county central committee or state central committee may commence an action in the superior court to enjoin misrepresentation by a candidate or committee in his or her behalf, in the manner prohibited by this section, to the effect that the candidate has the support of the state or county central committee involved.
