Opinion for the Court filed by Circuit Judge GARLAND.
Kеith Watters, an attorney, brought suit against 'the Washington Metropolitan Area Transit Authority (WMATA) for failing to honor an attorney’s lien on the proceeds of a settlement between WMATA and Wat-ters’ former client. We hold that WMA-TA’s sovereign immunity bars Watters’ lawsuit.
I
Approximately ten years ago, Watters represented Brenda Blocker in a personal injury action against WMATA in the District of Columbia. Under the retainer agreement signed by Blocker, Watters was entitled to 33.3% оf any recovery obtained in the case. After three and a half years of investigation and settlement negotiations, Blocker, apparently dissatisfied with the $55,000 compromise then under discussion between Watters and WMATA, dischаrged Watters. That same day, February 19, 1992, Blocker retained Bonita Rudd as her new attorney. On February 26, Watters sent WMATA a letter asserting an attorney’s lien, in the amount of one-third of $55,000, on any recovery Blocker might obtain from the Authority. WMATA did not respond. Rudd settled Blocker’s case for $60,000 on April 3, 1992, *39 and WMATA, disregarding Watters’ purported lien, paid the full amount to Blocker and Rudd.
Watters brought the instant suit against WMATA for breach of contract and “breach of duty to enforce equitable lien.” Compl. at 5. The district court dismissed Watters’ breach of contract claim, but after a trial found WMATA liable for failing to honor Watters’ lien. WMATA appeals from the judgment against it. 1
II
On appeal, WMATA contends that sovеreign immunity precludes Wat-ters from asserting or enforcing an attorney’s lien against funds in its possession. 2 WMATA was created by an interstate compact entered into by the District of Columbia and the states of Maryland and Virginia. 3 As we havе repeatedly held, the three signatories conferred each of their respective sovereign immunities, including the Eleventh Amendment immunity of the two states, upon the Authority. 4
There is no question that the three signatories’ sovereign immunity extends to suits for breach of attorney’s liens. The Eleventh Amendment gives the two states immunity from suit in federal court,
see California v. Deep Sea Research, Inc.,
We may find a waiver of sovereign immunity “only where stated by the most express language or by such overwhelming implications from the text as will leave no room for any other reasonable construction.”
Morris v. Washington Metro. Area Transit Auth.,
Although the WMATA Compact provides that WMATA may “[s]ue and be sued,” Compact § 12(a), we have held that provision to extend оnly as far as the more specific (and partial) waiver of sovereign immunity contained in section 80 of the Compact.
Morris,
The Authority shall be liable for its contracts and for its torts and those of its Directors, officers, employees and agent[s] committed in the conduct of аny proprietary function, in accordance with the law of the applicable signatory (including rules on conflict of laws), but shall not be liable for any torts occurring in the performance of a governmental functiоn.
Compact § 80 (emphasis added). This section falls far short of a clear and unequivocal waiver of WMATA’s immunity against attorney’s charging liens. On its face, section 80 makes no reference to liens or their enforcement, nor is there any implication in its text that the Authority’s funds may be made subject to equitable liens of any sort. In the District of Columbia,

an attorney’s lien against funds held by a third party (like WMATA) is not a contract with, or tort of, the third party, but rather is a “qualified right of property which a creditor has in or over specific property of his debtor, as security for the debt.”
Wolf v. Sherman,
Watters contended at oral argument that the breach of an attorney's lien constitutes a tort, and is thus covered by sectiоn 80's waiver of sovereign immunity for torts committed by the Authority. 9 But even if that contention were correct, 10 it begs the question of whether Watters could have placed a lien on WMATA's property in the first place. As we have noted above, the case law of the three signаtories indicates that he could not have. See supra note 6 and accompanying text.
Our conclusion that WMATA is immune from the imposition or enforcement of an attorney's lien is bolstered by the same considerations that have led the courts to hold that public funds are generally immune from equitable liens and garnishments unless expressly permitted by statute. As the District of Columbia Court of Appeals declared in G'runley Construction Co. v. District of Columbia, "The policy behind the rule is manifest: the day-to-day fiscal integrity of local government could not be maintained if judgment creditors could seize funds that have been earmarked for other purposes."
Ill
For the foregoing reasons, we conclude that WMATA is shielded by sovereign immunity from Watters’ suit for breaсh of duty to enforce an attorney’s lien. As a consequence, the district court is without jurisdiction to grant him the recovery he seeks. We therefore vacate the judgment of the district court, and remand with instructions to dismiss this casе for lack of jurisdiction.
Vacated and remanded.
Notes
. WMATA also filed a third-party complaint against Blocker and Rudd, which the district court dismissed. WMATA appeals that dismissal as well, but our determination that WMATA is immune from liability to Watters moots the Authority's third-party claim.
. WMATA did not raisе this defense in its answer to Watters' complaint, but did raise it both in subsequent filings in the district court and in its opening brief in this court. Sovereign immunity is a jurisdictional issue that may be raised at any time during the course of litigation.

In Blue Fox, the Supreme Court suggestеd that a suit to enforce an equitable lien does not come within the Federal Tort Claims Act, which waives the federal government's immunity for "tort claims, in the same manner and to the same extent as a private individual under like circumstances." 28 U.S.C. § 2674; see Blue Fox,
