Wickard v. Filburn is 1942. And the court's rejection of many New Deal programs as unconstitutional is what (as you know) drove FDR's court-packing plan - which changed how they ruled (albeit without passing).
Wickard relates to a New Deal program.
Many/most New Deal cases did nott reach the court for final adjudication by the Supremes until after 1937.
Hence the SC was dealing with New Deal and follow-on issues well into the '40s and even to a degree into the '50s.
