Does the term "First Amendment" refer to both the United States Constitution and the California First Amendment?

3 We use the term "First Amendment" to refer to both that provision of the United States Constitution and the parallel California constitutional provisions upon which plaintiffs also rely (Cal. Const., art. I, 2, 3). Although, as plaintiffs note, the California provisions have been said to afford even greater rights than the federal (e.g., Robins v. Pruneyard Shopping Center (1979) 23 Cal.3d 899, 908, 153 Cal.Rptr. 854, 592 P.2d 341), we do not perceive in the issues or in plaintiffs' arguments any necessity to distinguish between them.
