Judicial activism typically refers to a philosophy where courts take an active role in ensuring that justice is served and interpreting the Constitution in a way that reflects contemporary values and social needs. Therefore, the most fitting response to how judicial activism affects the court's decisions is:
The court will rule on the actions of the other branches or judicial precedent.
This means that judges may be more willing to overturn legislative or executive actions and set new legal precedents based on their interpretations of the law and the Constitution.
