MEMORANDUM/ORDER

The Pennsylvania Public Utility Commission moves to intervene as a party-plaintiff under Fed.R.Civ.P. 24(b).

This declaratory judgment action began in the bankruptcy court as an adversary proceeding filed by debtor, Metro Transportation Co. t/a Yellow Cab Company, against defendant Balboa Insurance Company.1 The complaint, filed on April 28, 1987, is for a declaration that Balboa is liable, under two automobile insurance policies issued to Metro, for the payment of all bodily injury and property damage claims asserted against Metro for the policy period from October 1,1984 to October 1,1986. Although the first policy contains a $35,000 deductible provision and the second a $50,-000 deductible, Metro maintains that Balboa is liable for “dollar one” coverage without regard to the deductibles. Metro contends that policy endorsements and certifi*424cations filed by Balboa with the intervenor movant Pennsylvania Public Utility Commission have the effect of amending the policies to conform with the PUC regulation, 52 Pa.Code § 29.104, which requires dollar one, or nondeductible, coverage. Balboa’s position is that it is liable for claims or judgments against Metro only in excess of the deductible limits stated in the policies of insurance.

On-June 27, 1987 the PUC filed its motion to intervene in bankruptcy court. It asserted it had authorized Metro to operate over 500 taxicabs in Philadelphia in reliance on the form filings with the Commission and that those filings establish Balboa’s liability on all accident claims against Metro from the first dollar to the minimum limits under state law. On July 17, 1987 Balboa filed a motion, later joined in by all the parties, for withdrawal of the reference of the adversary proceeding. On October 29, 1987 an order was entered granting the motion. 28 U.S.C. § 157(d).2

Permissive intervention is appropriate here. A PUC regulation, 52 Pa.Code § 29.104, forms the basis of Metro’s claim against Balboa. Under Fed.R.Civ.P. 24(b), there is “specific provision for intervention by governmental agencies interested in statutes, regulations or agreements relied upon by the parties in the action.” Halderman v. Pennhurst State School & Hosp., 612 F.2d 84, 92 (3d Cir. 1979), rev’d on other grounds, 451 U.S. 1, 101 S.Ct. 1531, 67 L.Ed.2d 694 (1981).3 Rule 24(b) expands the traditional concept of claim or defense insofar as intervention by a governmental officer or agency is concerned. Nuesse v. Camp, 385 F.2d 694, 705 (D.C.Cir. 1967). The rule requires that intervention be granted liberally to governmental agencies because they purport to speak for the public interest. 7C Wright & Miller, Federal Practice & Procedure § 1913, at 373-74 (1986). See Blowers v. Lawyers Coop. Publishing Co., 527 F.2d 333, 334 (2d Cir. 1975) (district courts should apply a “hospitable” approach to intervention motions by government agencies).

Intervention by the PUC is not likely to cause undue delay. On the contrary, its specialized knowledge of the regulations in question may expedite matters. Cf. Ellen-der v. Schweiker, 550 F.Supp. 1348, 1360 (S.D.N.Y. 1982). Its “claim” does not introduce new issues into the case since the claim made by Metro is identical. Moreover, the action is still in its early stages. See Group Health, Inc. v. Blue Cross Ass’n, 587 F.Supp. 887, 892 (S.D.N.Y. 1984). There is no evidence that the PUC’s intervention will prejudice Metro’s rights. Balboa’s argument that it will be prejudiced because “a jury is likely to be swayed by the fact that a commission of the Commonwealth favors one party over another” cannot overcome the wording of Rule 24(b) that expressly invites governmental agency intervention.
