A permanent injunction enjoining a city from enforcing, as unconstitutional, its ordinance regulating street vendors and door-to-door solicitors, is vacated in part, reversed in part, and remanded where: 1) plaintiffs-newspapers had standing for their claims; 2) the injunction need not be vacated based on mootness because the mootness was due to the city's voluntarily repealing portions of the ordinance; 3) as one provision has never been applied to the newspapers, and because its plain language was non-discriminatory and content-neutral, the district court erred in holding it unconstitutional, both facially and as applied; and 4) since the newspapers obtained the primary relief they sought in district court, they remained prevailing parties and were entitled to attorney's fees.
