occurred some years after their termination. While this might be a plausible reading of the statute, Louisiana courts have interpreted the statute more broadly. This precise issue was addressed in Pearce v. Austin, 465 So.2d 868 (La.App. 2d Cir.1985).
In Pearce, a Louisiana court of appeals overturned a trial court’s denial of attorney fees to an employee who was seeking commission payments. The trial court in Pearce had accepted the same argument urged here by Dantin and Foret: that the statute was inapplicable because the employee’s “commissions were not, at the time of [the employee’s] resignation, ‘then due’.” Id. at 872. The Louisiana appellate court responded that the “trial court gave a narrower reading to the statute than intended by the legislature” and concluded that the employee was entitled to attorney fees under the statute. Id. at 872-73. Foret and Dantin attempt to distinguish Pearce on the ground that the employee and his employer signed a letter agreement fixing the amount of the employee’s “anticipated” commissions at the time of his resignation. However, that letter agreement did not provide that the commissions were due immediately; instead, the parties intended, as was the customary business practice, that the commissions be paid when the job was completed.
Other Louisiana courts have applied sections 23:631 and 23:632 in suits initiated for the purpose of collecting commission payments. See, e.g., Hendricks v. Acadiana Profile, Inc., 484 So.2d 242 (La.App. 3rd Cir.1986) (awarding attorney’s fees in suit for commissions from the sale of ads); Ru-benstein Bros. v. LaForte, 320 So.2d 303 (La.App. 4th Cir.1975) (awarding attorney’s fees in suit for commissions from the sale of “special order” clothing, which customers could later reject). Finally, Louisiana courts specifically have found that section 23:632 mandates an award of reasonable attorney’s fees whenever an employee files a well-founded suit for any unpaid wages or commissions. See Carriere v. Pee Wee’s Equipment Co., 364 So.2d 555, 556 (La.1978); Hendricks, 484 So.2d at 246; Pearce, 465 So.2d at 873; Rubenstein, 320 So.2d at 307.
Given this list of Louisiana cases, we are at a loss to understand how appellants could have determined, in good faith, that appeal of the district court’s determination on this issue was warranted. By signing the pleadings, counsel for appellants not only represented that he had read the pleadings but certified that such pleadings were “well grounded in fact ... warranted by existing law ... and that [such pleadings] [were] not interposed for any improper purpose, such as to harass or to cause unnecessary delay or needless increase in the cost of litigation.” Fed.R.Civ.P. 11; La.Code Civ.Proc.Ann. art. 863(B) (West Supp.1990). For counsel to now argue against the facts and claims contained in those pleadings is somewhat disingenuous if not totally spurious. Louisiana case law clearly showed that attorney’s fees could be supported in the type of suit brought by appellants, and this should have convinced them that they could not meet the heavy burden of the legal certainty test established in St. Paul.
The district court committed no error by exercising jurisdiction over this matter and was justified in refusing to remand the case to the Louisiana state court.
B. Res Judicata
For the claim made by Dantin and Foret to be barred by res judicata the district court must have found that: 1) the prior judgment was rendered by a court of competent jurisdiction, 2) the parties to both suits were identical, 3) the prior judgment was a final judgment on the merits, and 4) the prior judgment was based on the same cause of action. See Nilsen v. City of Moss Point, 701 F.2d 556, 559 (5th Cir.1983) (en banc).
There is little doubt that the first three elements of the Nilsen test have been met. First, Foret and Dantin do not dispute that the federal district court had jurisdiction over the Gribbin suit. They do argue, however, that the federal district
