Case Law (e.g., Campbell v. Acuff-Rose Music, Inc.)

Case law refers to laws that are established based on the outcomes of previous court cases, helping to interpret and apply legal principles. In the case of **Campbell v. Acuff-Rose Music, Inc.**, the U.S. Supreme Court ruled that parody can qualify as fair use of copyrighted material, allowing new works that comment on or criticize originals. This decision emphasized that the purpose and character of the use are critical in assessing fair use, balancing the rights of creators with freedom of expression. It shaped how copyright law views transformative works in relation to original content.
