A frivolous appeal is a legal term used to describe an appeal that lacks any serious purpose or value. It often involves arguments that are not based on substantial evidence or legal principles, making it unlikely to succeed. Courts may dismiss these appeals to prevent wasting time and resources. In many jurisdictions, filing a frivolous appeal can lead to penalties, including fines or sanctions against the appealing party. This is intended to discourage individuals from misusing the legal system, ensuring that legitimate cases receive the attention they deserve while maintaining judicial efficiency.
