For roughly 40 years the Supreme Court struck down minimum-wage, maximum-hour and child-labor laws in the name of 'liberty of contract,' a right found nowhere in the text. The episode covers Lochner, Hammer v. Dagenhart and Adkins, and Justice Holmes's dissent that the 14th Amendment does not enact one economic theory. It is activism from the right, the mirror of what critics later attacked from the left.
Historians split on whether Lochner was sincere liberty jurisprudence or pro-business favoritism. The popular 'switch in time' story is also complicated by Roberts voting to uphold the Washington law in December 1936, before the packing plan.
