Hugo Black,
Donovan v. City of Dallas — Opinion of the Court
“ Since we hold the order restraining petitioners from prosecuting their case in the federal courts was not valid, but was invalid, petitioners have been punished for disobeying an invalid order. Whether the Texas court would have punished petitioners for contempt had it known that the restraining order petitioners violated was invalid, we do not know. However, since that question was neither considered nor decided by the Texas court, we leave it for consideration by that court on remand. ”
