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:
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.
For this, the court can refer to a previous judgement as basis for their own judgement. Thus, court precedents are enforceable by law.
Precedents set by a President serve at best, as guidelines.
They are simply acts performed by a previous President when met with a similar situation.
