Judicial review has significant implications for governmental actions, as it allows courts to assess the constitutionality of laws and executive actions. By striking down unconstitutional measures, judicial review protects individual rights and promotes the rule of law. This process can serve as a check on governmental power, ensuring that authorities do not overreach or violate citizens' freedoms. Moreover, judicial review can influence public policy by interpreting laws in ways that reflect societal values and norms. Ultimately, it plays a critical role in maintaining a balance between governmental authority and individual liberties.
