Read the following paragraph and determine if the hypothesis is true:

But there has to be a limit, as you acknowledge. Perpetual copyright is not permitted. Who is the judge of -- within that line? Who is the judge of when it becomes unlimited? Is there, in other words, judicial review and, if there is, what standard would this Court apply to determine whether something short of perpetual is still unlimited?

Hypothesis: Copyrights only last for a limited time.
Yes
