Does judicial review really strengthen the constitutional principal of checks and balances out not?

Yes, judicial review does strengthen the constitutional principle of checks and balances. By allowing the judicial branch to review and potentially overturn actions taken by the executive or legislative branches that are deemed unconstitutional, judicial review serves as a key mechanism for ensuring that the powers of government are balanced and kept in check. This helps prevent any one branch from becoming too powerful and infringing on the rights and liberties of individuals.
