Roughly five thousand Peruvian citizens filed a lawsuit of unconstitutionality against part of Law 30407, which allowed events such as cockfights and bullfights in the name of cultural character and expression. The plaintiffs raised animal welfare arguments, particularly, and certain animals' biological abilities to feel emotions and have moral capacity. They also balanced human fun and culture and animal welfare, arguing that human fun should not be at the expense of the suffering of animals. The court was divided in its opinions and varied in whether it believed the claim was founded. Many areas were discussed, including biology, history, morality, cultural studies, and legal precedent. The court was so divided that it did not come to a conclusion in this opinion per the Organic Law of the Constitutional Court.
