Why did the supreme court oppose some of roosevelts programs?

The Supreme Court opposed some of Franklin D. Roosevelt's programs primarily because they believed certain New Deal policies exceeded the federal government's constitutional powers. The Court ruled that some legislation, like the National Industrial Recovery Act and the Agricultural Adjustment Act, infringed on states' rights and regulated local businesses in ways that were deemed unconstitutional. This judicial pushback led to tensions between the executive and judicial branches, prompting Roosevelt to propose a controversial court-packing plan that aimed to increase the number of justices. Ultimately, the Court's resistance reflected broader concerns about the balance of power and the limits of federal authority.
