Bravo Enterprises, Inc. (Bravo) (defendant) sought to hold a series of bullfighting events in Philadelphia beginning in April 1966. Prior to the first bullfighting event, the Pennsylvania Society for the Prevention of Cruelty to Animals (SPCA) (plaintiff) brought an equitable action to enjoin the event. The Court of Common Pleas of Philadelphia County initially denied SPCA’s motion for an injunction and held a hearing after the first performance. At the initial hearing, the bullfighting events were enjoined until the final hearing. At the final hearing, both SPCA and Bravo presented evidence and testimony, and the court of common pleas issued an injunction permanently enjoining Bravo from holding additional bullfighting events. Bravo appealed the decision, arguing that the bullfighting events did not violate the law and that SPCA lacked standing to bring a claim for an injunction.
