Final answer:
The Supreme Court opposed Roosevelt's New Deal due to its expansive interpretation of federal power, ruling major components unconstitutional and prompting Roosevelt to propose a controversial court-packing plan to safeguard his agenda.
Step-by-step explanation:
Resistance from the Supreme Court Against Roosevelt's New Deal
President Franklin Roosevelt's New Deal faced significant resistance from a conservative-dominated Supreme Court, which held a dual-federalism viewpoint that saw the New Deal's expansion of federal power as unconstitutional. This was evident when the Court declared central components, like the National Industrial Recovery Act (NRA) and the Agricultural Adjustment Act (AAA), invalid, citing an overreach into the powers reserved for states. In response to the Court's systematic invalidation of his New Deal legislation and sensing a threat to his agenda, Roosevelt introduced the judicial reform bill of 1937, widely viewed as a court-packing scheme, to appoint additional justices that would be amenable to his policies. However, public reaction was mixed to this proposed increase in executive power, leading many, including supporters and prominent Democrats, to question Roosevelt's motives and resulted in a constitutional controversy.
