This assignment provides legal advice to Lei Lan, a young composer and singer, regarding potential copyright infringement issues. The advice addresses whether Lei Lan is liable for using lyrics written by others, including Shakespeare and contemporary artists like Kanye West, in her songs. It analyzes relevant Australian copyright law, specifically the Copyright Act 1968 (Cth), and discusses key concepts such as copyright ownership, infringement, and available defenses. The analysis includes case law examples, such as the Taylor Swift "Shake it Off" case and the Men at Work "Down Under" case, to illustrate the application of copyright principles. The advice concludes that Lei Lan is likely liable for copyright infringement due to unauthorized use of lyrics and suggests she cease using others' lyrics without permission to avoid further legal action. The document also outlines potential remedies the court may impose, such as damages, royalties, and injunctions.
