In Rescue Army v. Municipal Court (1946) 28 Cal.2d 460, the California Supreme Court upheld a portion of the Los Angeles regulatory ordinance which permitted the Department of Social Service to withhold a permit for solicitations conducted by means of a fixed receptacle situated in publicly owned or controlled places, if the information furnished to the department disclosed fraud. The opinion took pains to point out that prior restraint was warranted only under the peculiar factual situation in which use of information cards was ineffective, and that many other avenues of solicitation without prior restraints remained open to those who were refused a permit to maintain a fixed collection receptacle.
