A bill to amend title 28, United States Code, to provide for a declaratory judgement in certain cases involving public utilities.

Requires a court of the United States in certain circumstances to issue a declaratory judgment in a case of actual controversy between a public utility and either the Secretary of the Treasury or a ratemaking body, with respect to specified provisions of the Internal Revenue Code of 1954 dealing with either the computation of credit for investment in depreciable property or depreciation deductions. Allows the court to issue such a judgment following its determination that the public utility has either obtained a ruling from the Secretary of the Treasury, or has requested such ruling and the Secretary has failed to respond within 180 days.
