A more thorough explanation:

A perfect right is a term used to describe something that is proper under law, morality, or ethics. It refers to a legally enforceable claim that another person will do or will not do a given act. It is a recognized and protected interest, the violation of which is a wrong.

For example, a person has a perfect right to their personal liberty, which means that they have the legal guarantee to be free from physical restraint or confinement. Another example is the right to dispose of one's estate, which means that a person has the power and privilege to distribute their property after their death according to their wishes.

Overall, a perfect right is a fundamental aspect of the legal system that protects individuals from harm and ensures that they are treated fairly and justly under the law.
