OPINION
We answer the question that must be on everyone’s mind: Is the State of California barred from invoking its sovereign immunity in federal court because it waived this immunity through participation in a predecessor lawsuit?

Interstate 710 has been kept about four miles away from completion by 29 years of federal litigation. This legal journey began in January 1973, when the City of South Pasadena
The studies were finally completed by April 1998 and the project thereafter re
The district court ruled that the final approval of the environmental report was “not a significant intervening event to justify the filing of a supplemental complaint 25 years after the original complaint.” Order of Aug. 28, 1998, at 3. Rather, completion of the studies meant that the litigation had achieved its main goal, and that the state was no longer bound by the 1973 stipulation. The district court also pointed out that a supplemental pleading “cannot be used to introduce a ‘separate, distinct and new cause of action,’ ” id. at 4 (quoting Planned Parenthood of S. Ariz. v. Neely,
The parties then stipulated to dismissal of the 1973 lawsuit. Two days later, the city commenced a new federal action, raising many of the claims in its attempted supplemental complaint. About three months later, the city amended the new complaint to import related state law claims from a separate action it had filed in state court; the state court action was stayed and is still pending.
The state promptly invoked sovereign immunity against litigating the state law claims in federal court. The district court rejected this defense, holding that the state had waived its Eleventh Amendment immunity in the course of the 1973 litigation. City of S. Pasadena v. Slater,
II
The parties spill much ink arguing whether, under Hill v. Blind Industries and Services of Maryland,
[2] By failing to invoke the immunity defense during the pendency of the 1973 action, the state waived it. See ITSI TV Prods., Inc. v. Agric. Ass’ns,
Ill
The state’s earlier immunity waiver only helps plaintiffs if it carries over to the current lawsuit. The city, however, voluntarily dismissed the 1973 action pursuant to Fed.R.Civ.P. 41(a)(l)(ii). This was the city’s first voluntary dismissal, and it was therefore without prejudice.
We have adhered slavishly to this interpretation of Rule 41(a). See, e.g., Commercial Space Mgmt. Co. v. Boeing Co.,
The city argues that there is “[no] categorical rule that a waiver of sovereign immunity cannot carry over to a subsequent action.” This is not surprising, because Fed.R.Civ.P. 41(a)(1) provides a categorical rule that is much broader — one that disallows the “carry-over” of any waivers from a voluntarily dismissed action to its reincarnation. South Pasadena does not explain why we should carve out an exception to this rule for waivers of sovereign immunity. If there were a special rule applicable to this situation, it would cut the other way: Because waivers of sovereign immunity are narrowly construed, see Atascadero State Hosp. v. Scanlon,
Because the state promptly raised the immunity defense against state law claims in the current litigation, and because these claims are undisputably of the type barred by the Eleventh Amendment, the district court erred in failing to dismiss them.
REVERSED and REMANDED for dismissal of all claims based on state law.
Notes
. Joining the city as plaintiffs in the lawsuit were three environmental groups and three individuals.
. By contrast, if the party filing for voluntary dismissal has already once dismissed “an action based on or including the same claim,” the second dismissal operates as an adjudication on the merits. Fed.R.Civ.P. 41(a)(1).
. Rule 41(a)(1) has a few limited exceptions, notably allowing "consider[ation of] collateral issues,” such as Rule 11 sanctions for conduct that took place before dismissal, Cooter & Gell v. Hartmarx Corp.,
. Although Humphreys discussed Rule 41(a)(2), which governs voluntary dismissal by order of the court, rather than Rule 41(a)(1), which permits such dismissal without the court's approval, the reasoning applies with equal force to both provisions. See Concha,
