The Supreme Court (not the Roberts Court, historical) has ruled:
* That banning yellow dog contracts (anti-union contracts) vioalted the due process clause of the constitution (Adair v United States)
* That the government can unilaterally breach treaties with native tribes without compensation (Lone Wolf v Hitchcock)
* That limiting the number of hours people could work to 60 violated the Due Process clause (Lochner)
* That the Sherman Antitrust Act prevented union secondary boycotts
