Frank Murphy, Comstock v. Group of Institutional Investors…
“ Standard Gas & Electric Co., supra, this Court established the principle that where a parent corporation has not only dominated but has mismanaged a subsidiary corporation, which is presently in bankruptcy or reorganization, and where the parent has a claim which is intimately related to the mismanagement, a court may refuse to permit the parent to assert the claim as a creditor except in subordination to the claims of the subsidiary's other creditor and preferred stockholders. This principle, which has become known as the Deep Rock doctrine, is equitable in nature. ”
