Jerry Armer and William Fetters brought this suit under 42 U.S.C. Sec. 1983 against appellees, the City of Salem, Missouri, the City's Mayor, and four individual members of the City's Board of Aldermen, claiming that their rights to procedural due process were violated when they were discharged from their positions as city police officers without notice or a hearing. The district court1 granted summary judgment in favor of appellees. We affirm.

Armer and Fetters were hired as police officers for the City of Salem, a fourth-class city, in October, 1981 and March, 1982, respectively. On December 1, 1986, the Board of Aldermen met in a private session and voted, 3-1, to dismiss Armer and Fetters from their positions. Armer and Fetters were informed of this action in separate letters signed by the Mayor; the letters did not state the reason for the dismissals. Armer and Fetters then requested and were granted a hearing before the Board of Aldermen. At that hearing, the Board voted to uphold the terminations and again did not disclose the reason for its decision. Armer and Fetters then filed this suit under 42 U.S.C. Sec. 1983, claiming that Salem city ordinances gave them a property interest in their jobs and that the City failed to afford them procedural due process when it discharged them. The district court rejected their claim, holding that under the applicable Missouri statute police officers of fourth-class cities such as Salem are at-will employees and that this state statute overrides any city ordinance to the contrary.

To demonstrate that they had a property interest in their jobs protected by the Due Process Clause, appellants must show by reference to a specific source, such as a contract or statute, that they had a legitimate claim of entitlement to continued employment. Board of Regents v. Roth, 408 U.S. 564, 577, 92 S. Ct. 2701, 2709, 33 L. Ed. 2d 548 (1972). Whether such a claim of entitlement exists is decided by reference to state law. Bishop v. Wood, 426 U.S. 341, 344, 96 S. Ct. 2074, 2077, 48 L. Ed. 2d 684 (1976).

According to section 79.240 of the Missouri Revised Statutes, appointive officers of fourth-class cities are terminable at will by the mayor acting with the consent of a majority of the aldermen or by two-thirds of the aldermen acting independently of the mayor. Mo.Rev.Stat. Sec. 79.240 (1986).2 As the district court noted, Missouri courts have consistently treated fourth-class city police officers as "appointive officers" within the meaning of Sec. 79.240. See Amaan v. City of Eureka, 615 S.W.2d 414 (Mo. banc), cert. denied, 454 U.S. 1084, 102 S. Ct. 642, 70 L. Ed. 2d 619 (1981); Pumphrey v. City of Lutesville, 707 S.W.2d 475 (Mo.Ct.App.1986); State ex rel. Ciaramitaro v. City of Charlack, 679 S.W.2d 405 (Mo.Ct.App.1984). Thus, under Missouri law fourth-class city police officers do not have a property interest in their jobs implicating due process requirements.

Nevertheless, appellants argue that their employment status is not governed by the "appointive officer" provision of Sec. 79.240 because they are not appointive officers within the meaning of that statute. They claim that under Salem city ordinances police officers are "permanent employees" removable only for cause after notice and a hearing. Even assuming that Salem ordinances attempt to give police officers a permanent employee status, we reject this argument because Sec. 79.240 controls over any city ordinance to the contrary which purports to change fourth-class city appointive officers' status from that of at-will. Pumphrey, 707 S.W.2d at 477. Salem ordinances cannot override Sec. 79.240 by attempting to classify police officers as something other than "appointive officers" in order to place them beyond the reach of Sec. 79.240, especially where the Missouri courts have established that fourth-class city police officers are governed by the "appointive officer" provision of Sec. 79.240.3

In short, Sec. 79.240 assigns at-will status to appointive officers of fourth-class cities, the Missouri courts have consistently interpreted Sec. 79.240 to include police officers as appointive officers, and city ordinances to the contrary are not effective to change fourth-class city police officers' employment status.

Appellants also argue that the City is estopped from denying the validity of its ordinances because they relied on its representation that they were more than at-will employees. This argument is without merit because in Missouri the doctrine of estoppel is generally not applicable against governmental bodies. Farmers' & Laborers' Coop. Ins. Ass'n v. Director of Revenue, 742 S.W.2d 141, 143 (Mo. banc 1987); Bartlett & Co. Grain v. Director of Revenue, 649 S.W.2d 220, 224 (Mo.1983). Missouri has deviated from this rule in exceptional circumstances where manifest injustice would result from a refusal to apply the doctrine. See, e.g., Murrell v. Wolff, 408 S.W.2d 842, 851 (Mo.1966) (reliance upon an honestly obtained permit coupled with substantial expenditures). However, we do not find such circumstances present in this case.

We hold that appellants did not have a property interest in their jobs implicating the Due Process Clause. They served as at-will employees under Sec. 79.240, and thus were removable for any reason or no reason. Contrary city ordinances, to the extent that any exist, are not effective to assign them any greater status. Accordingly, we affirm.
