William O. Douglas,
Board Of Regents Of University Of Texas System v…
“ The three-judge-court statute, 28 U.S.C. § 2281, speaks of 'the enforcement, operation or execution of any State statute.' A city ordinance or a county regulation does not meet that requirement, and so the county regulations involved in Moody did not satisfy the statute though enacted by the State. If the source of the authority is state action, the statute is presumably satisfied, since normally of course, state laws have an impact on activities in every city and every county. ”
