Explanation:
Hi,
Without Judicial review, some laws might be passed that may then be seen as unconstitutional. Rights would be violated and people would feel as if they weren't being treated equally. Judicial review also makes sure that power is equal between all branches to avoid conflict. Without the Judicial review, not only with power be uncontrolled between the branches, but many laws would be unconstitutional and prevent people from gaining their god-given rights.
Hope this helps :)
