Case: Salib v$.$ City of Mesa$[1]$

Facts: Edward Salib owned a Winchell$$s Donut House in Mesa, Arizona. Salib displayed large signs in his store window. The City ordered Salib to remove the signs as they violated the Sign Code which prohibited covering more than $30\%$ of store$$s windows with signs. Salib sued claiming the Sign Code violated his First Amendment rights to commercial speech. The trial court ruled in favor of Mesa, finding that the ordinance did not violate his $1$st amendment rights to commercial speech and Salib appealed.
