Opinion for the Court filed by Chief Judge WALD.
Appellant Horn & Hardart Company (Horn & Hardart) seeks review of a district court decision granting a motion by appel-lee National Railroad Passenger Corporation (Amtrak) for “further relief” under the Declaratory Judgment Act. 1 Specifically, the district court enforced liquidated-damages and cost-on-default contract provisions against Horn & Hardart, the lessee of restaurant space in Amtrak’s Pennsylvania Station in New York City. 2
Horn & Hardart, a Nevada corporation involved in the food services industry, entered into three leases with Amtrak on June 1, 1980, for restaurant space in Pennsylvania Station, New York City. On November 29, 1984, Amtrak informed Horn & Hardart that it intended to terminate all three leases pursuant to provisions that authorized such termination when corporate or construction purposes so required, and demanded that Horn & Hardart vacate the premises by February 28, 1985. Instead, Horn & Hardart instituted an action based on the Declaratory Judgment Act seeking a ruling that the terminations violated the lease provisions. Horn & Har-dart also sought an injunction against Amtrak’s seeking an eviction as well as $2.5 million in damages for losses suffered by Horn & Hardart as a result of Amtrak’s actions. This action, based on an alleged failure of Amtrak to abide by the notice of termination clauses, was unsuccessful. First, the district court,

No. 85-0820, mem.op. (D.D.C. May 30, 1985)
(Horn & Hardart I)
[available on WESTLAW,
The district court, relying on § 2202, enforced the leases’ end-of-term holdover and-cost-on-default clauses, and awarded Amtrak $335,017.30 in damages and $52,562.02 in attorney’s fees.
Horn & Hardart Co. v. National Railroad Passenger Corp.,
*548 A. Jurisdiction
First, appellant-Horn & Hardart’s argument that the district court lost jurisdiction once its initial judgment was appealed to this court is mistaken. The “further relief" provisions of both state and federal declaratory judgment statutes clearly anticipate ancillary or subsequent coercion to make an original declaratory judgment effective.

Neither a completed appeal,
see McNally v. American States Insurance Co.,
B. The Declaratory Judgment Act
Section 2202 of the Declaratory Judgment Act provides for “necessary or
proper
relief” — specifically, “proper relief
based
on the declaratory judgment.” 28 U.S.C. § 2202 (emphases added). Amtrak’s request for further relief in the form of triple rent and attorneys’ fees follows absolutely from, and is based on, the district court’s decision in
Horn & Hardart I
confirming Amtrak’s right to terminate the leasehold.
5
And even though Amtrak's present request may not be “necessary” to effectuate the lease termination ruling, the plain language of the Declaratory Judgment Act does not require this degree of stringency. The relief need only be proper.
See, e.g., Besler v. United States Dept. of Agriculture,
C. Res Judicata
The district court properly rejected Horn & Hardart’s third objection that Amtrak’s claims for further relief are barred by
res judicata
doctrine. It ruled that ordinary principles of claim preclusion do not apply to § 2202 actions given their clear purpose of supplementing declaratory relief.
See, e.g., Kaspar Wire Works, Inc. v. Leco Engineering & Mach., Inc.,
Horn & Hardart attempts to rebut reliance on the declaratory judgment exception to claim preclusion with the observation that where a plaintiffs original action seeks coercive or injunctive, as well as declaratory, relief, traditional rules of claim preclusion may apply to bar later actions. This bar could only affect Amtrak, however, had it filed an answer, thereby making its own counterclaims ripe. In this ease, Rule 13(a)’s compulsory counterclaim requirement never became relevant.
6
For a counterclaim to be compulsory, Amtrak would have to have been obliged to submit responsive pleadings,
see
Restatement (Second) of Judgments § 21 (defendant who prevails on counterclaim is treated as plaintiff and rules of merger apply). Instead, Amtrak merely filed a motion to dismiss, which under Fed.R.Civ.P. 12(b)(6) is not such a responsive pleading. Summary disposition was entered before Amtrak was required to submit an answer.
See United States v. Snider,
D. Merits
Reaching the merits, we find that the plain and straight-forward language of the leases controls. The leases stated that because Amtrak would incur considerable costs if Horn & Hardart failed to vacate upon notice of termination,
see Horn & Hardart II,
We conclude that Horn & Hardart cannot escape its contractual obligations, which Amtrak now seeks to pursue under § 2202, Appeal from an adverse declaratory judgment does not erect a jurisdictional bar to further relief in the district court based on the original judgment, nor does the doctrine of claim preclusion bar a valid § 2202 “further relief” action in the circumstances of this case where the defendant was never required to assert counterclaims in the original suit. Although our explication of the issues differs in some respects from the trial court’s rationale, we agree with the district court that none of Horn & Hardart’s procedural or substantive arguments will permit that corporation to escape its contractual liability to Amtrak.
Affirmed.
Notes
. Section 2202 reads:
Further necessary or proper relief based on a declaratory judgment or decree may be granted, after reasonable notice and hearing, against any adverse party whose rights have been determined by such judgment.
28 U.S.C. § 2202.
. The end-of-term holdover clauses concerning liquidated damages uniformly provide:
Lessee ... agrees that if possession of the demised premises is not surrendered to the Lessor within seven days of the date of expiration or sooner termination of the term of this lease, then Lessee agrees to pay Lessor as liquidated damages for each month and for each portion of any month during which Lessee holds over in the premises after expiration or termination of the term of this lease, a sum equal to three times the average rent and additional rent which was payable per month under this lease during the last six months of the term thereof.
See Horn & Hardart Co.
v.
National Railroad Passenger Corp.,
The leases also included provisions that required Horn & Hardart to pay costs and expenses, including attorneys’ fees, suffered by Amtrak because of a " ‘default in the observance or performance of any term or covenant on Lessee’s part_”’ Id. at 1268 (emphasis omitted).
. Horn & Hardart’s reliance on
Overnite Transportation Co. v. Chicago Industrial Tire Co.,
. See also Anderson, Actions for Declaratory Judgments § 451 (2d ed. 1951 & Supp.1959). Anderson writes:
While it is true that the declaratory judgment statute does not authorize the retention by the court of any jurisdiction after entertaining a declaratory judgment, yet it does not follow that a court may not retain jurisdiction to enter such subsequent orders that will make effective the declaratory judgment that has been granted. The power of the court of equity to retain jurisdiction to give complete and effectual relief is well established, and it follows without any serious controversy that the court may make such further orders to give effect to a declaratory judgment as shall seem meet and proper.
Id. at 1058.
.We note that were the subsequent action for § 2202 further relief to occur unfairly late, suit might be barred by the doctrine of laches. No such concern exists in the present case.
. Because Rule 13 did not become timely, we do not consider the possibility that § 2202’s provision for supplementary relief might actually enlarge the declaratory judgment exception to claim preclusion to permit a supplemental action even where the original action involved more than declaratory relief.
Cf. Edward B. Marks Music Corp. v. Charles K. Harris Music Corp.,
. Indeed, § 2202’s post-judgment relief need not be demanded, or even proved, in the original action.
See Edward B. Marks Music Corp. v. Charles K. Harris Music Publishing Co.,
. Amtrak’s twin claims for triple rent damages and attorneys’ fees are based on the leases’ clauses cited in note 2,
supra.
Because both claims involve sums that have a reasonable relation to the probable damages Amtrak incurred from Horn & Hardart's holdover, these automatic forfeitures do not constitute a penalty which would be invalid under
