This is the second appeal in this case. In the first appeal, we reversed the district court’s partial summary judgment in favor of Illinois Central and remanded for trial upon a single issue of disputed fact regarding whether Illinois Central could prove that there was a public demand for its proposed expropriation. 1 On remand, the district court held a bench trial that included two full days of testimony in which numerous shippers presented evidence of their demand for the proposed railroad spur. Even the Mayeuxs’ expert witness conceded that there was a public demand during his testimony. The district court decided that Illinois Central had proven the existence of the requisite public demand for this project.

The Mayeuxs challenge the district court’s decision on two grounds. First, the Mayeuxs claim that the district court deviated from this court’s mandate when it limited its examination to whether Illinois Central had established a public demand for the railway service track. Second, the Mayeuxs argue that the district court used an outdated standard for determining whether such a public demand existed by relying on jurisprudence predating the 1974 revisions to the Louisiana state Constitution. We find that the district court faithfully followed our mandate, and we *221 are precluded from reaching the Mayeuxs’ second argument.

In the first decision on appeal, we recognized that the existence of a public demand for the railroad spur was a key aspect of the necessary purpose inquiry required for expropriation under Louisiana law. 2 While there are other factors that go into the consideration of whether a proposed expropriation meets a necessary purpose, 3 because the Mayeuxs had challenged only whether sufficient public demand supported the expropriation and had presented expert testimony that conflicted with the railroad’s evidence on this point, we remanded the case to the district court to resolve that dispute. 4 Specifically, this court found that there was a genuine dispute as to but one issue of material fact, 1. e. whether there was a public demand for the project, and therefore ordered the district court to try this single issue without further consideration of whether the other aspects of the necessary purpose inquiry, which had not been contested by the parties, had been met. 5 As the mandate has issued in this court’s prior decision, any consideration of the finally adjudicated aspects of necessary purpose would be improper at this point. 6 Thus, the issue before this panel is whether the district court erred in finding that there was public demand for the expropriation.

After reviewing the record in this case, the briefs and oral argument of the parties, as well as the district court’s reasons for its judgment, we conclude that the evidence fully supports the trial court’s decision on the public demand issue and its judgment of expropriation. Accordingly, we affirm the district court’s judgment in full.

AFFIRMED
