What can judicial branch do if the executive branch veto's a bill?

If the executive branch vetoes a bill, the judicial branch does not have a direct role in the veto process itself, as its function primarily involves interpreting laws rather than enacting or rejecting them. However, if a party believes the veto was unconstitutional or violated legal principles, they can challenge it in court. The judicial branch can then review the case and determine whether the veto was lawful or if the bill should be reinstated. Ultimately, the judicial branch's authority is limited to interpreting the law rather than overriding a veto.
