Stanley Forman Reed,
Petroleum Exploration v. Public Service Commission of Kentucky…
“ In both cases this Court dealt with the merits of the respective orders, determining that there was no constitutional basis for saying that 'any person is immune from giving information appropriate to a legislative or judicial inquiry.' Here there is no need to consider the validity of the challenged order. To justify the use of the extraordinary power of a court of equity something more must be involved than an application of a statute in an unconstitutional manner against complainant. ”
