charge an employee unconstitutionally sound in tort, not contract, id. at 688, and that the one year statute provided by § 5298(2) should apply. The district court was therefore correct when it made a like assumption in this case.
We face a more difficult question when it comes to the tolling issue. Here the district judge who decided the instant case is at odds with his colleague who ruled in Graf-fals. The tolling of the one year period provided by § 5298(2) is governed by P.R. Laws Ann. tit. 31, § 5303, which states:
“Prescription of actions is interrupted by their institution before the courts, by extrajudicial claim of the creditor, and by any act of acknowledgment of the debt by the debtor.”
In interpreting the phrase “their institution before the courts,” the district judge in Graffals v. Garcia, supra, ruled “that said action be the one exercised, not another one that is more or less analogous.” 415 F.Supp. at 20 (italics in original). This court, in approving that holding, noted that the opposing party did not “seriously quarrel with this conclusion.” 550 F.2d at 688.
But the district judge here, although aware of our decision in Graffals, was persuaded to interpret § 5303 differently. Believing that the combined common and civil law system of Puerto Rico requires a more flexible approach than that of the Spanish Civil Code, the judge held that the institution of any action between the same parties that constituted a diligent pursuit of the right claimed in the later action would come within § 5303 and would therefore toll the statute of limitations. The court held, in particular, that an action of mandamus in the Commonwealth court to gain reinstatement constituted a diligent pursuit of the constitutional right sought in plaintiff’s § 1983 suit and accordingly tolled the statute of limitations.
Although as an ordinary matter the interpretation of local law pertaining to a statute of limitations by the district court sitting in that jurisdiction is entitled to great deference from a reviewing court, see Runyon v. McCrary, 427 U.S. 160, 181-82, 96 S.Ct. 2586, 49 L.Ed.2d 415 (1976); Graffals v. Garcia, supra, 550 F.2d at 688, the existence of a sharp conflict among the judges of that district undercuts this deference and compels an independent assessment of the question by a court of appeals. In this case, the language of the statute tends to support the position taken in Graffals: by referring to “their institution”, the statute appears to state that it is the commencement of the action at bar, and not some other action, which tolls the period of limitation. Conceding the absence of any Commonwealth judicial authority on the matter one way or the other, the district judge in Graffals found direct support for his interpretation in an authoritative commentary on the identical provision in the Spanish Civil Code. See 12 Manresa, Comentarios al Codigo Civil Español 955 (1951 ed.). The district judge in the case at bar grounded a contrary interpretation on his view of the structure of the judicial system of Puerto Rico, which commingles elements of common and civil law. He also cited certain different commentators on the Spanish Civil Code as supporting, indirectly, a more liberal interpretation of the tolling provision.
To the extent the district court grounded its ruling on its sense of developments in the common rather than civil law, it is important to note that in the American common law generally, prior judicial actions do not toll the statute of limitations, no matter how close their relationship to the one at bar. See, e. g., UAW v. Hoosier Cardinal Corp., 383 U.S. 696, 708, 86 S.Ct. 1107, 16 L.Ed.2d 192 (1966); Falsetti v. Local No. 2026, UMW, 355 F.2d 658, 662 & n. 15 (3d Cir. 1966).3 Federal courts have

An exception to this rule exists for prior actions that bar the bringing of a subsequent suit during their pendency. See 54 C.J.S. Limitations of Actions § 247. The filing of plaintiffs mandamus suit, however, could not have acted as a bar to a simultaneous proceeding in federal court. See General Atomic Co. v. Felter, 434 U.S. 12, 98 S.Ct. 76, 54 L.Ed.2d 199 (U.S. Oct. 31, 1977); Donovan v. City of Dallas, 377 U.S. 408, 84 S.Ct. 1579, 12 L.Ed.2d 409 (1964).
