Court precedents are used in case of having no clear interpretation of the law for a particular case. President's precedents are simply acts performed by a President in a similar situation.
Explanation:
<u>Court precedents serve as an alternate to written laws when the existing guided laws are not suitable or simply not enough for a particular situation that arises.</u>
