I want to know the answer to the following question:
What is it called when a law disallows copyright owners from denying a license for certain uses?
All the background I'm provided with is that "Another example is the practice of compulsory licensing, which is where the law forbids copyright owners from denying a license for certain uses of certain kinds of works, such as compilations and live performances of music.". Is that enough to answer the question?
Answer: yes
