Ferro Corporation, Defendant-Appellee; Will Gaspard; et al., Plaintiffs-Appellants, v. Ed Frindt, Plant Manager; Ferro Corporation, Defendants-Appellees, 314 F. App'x 662

PER CURIAM: The parties dispute whether the amount in controversy is sufficient for diversity jurisdiction. We have reviewed the briefs and pertinent portions of the record and have heard the arguments of counsel. We also have consulted applicable sources of law. We can look to similar cases to assist in determining the amount in controversy. See, e.g., Marcel v. Pool Co., 5 F.3d 81, 82-83 (5th Cir.1993). This case is largely controlled and informed by No. 07-30530, In re 199b Exxon Chem. Fire, 558 F.3d 378 (5th Cir.2009).

The district court, albeit without benefit of the decision in Exxon, correctly decided that the amount-in-controversy requirement is satisfied. Because plaintiffs presented no expert testimony in support of causation, there is no error in the

summary judgment to Ferro Corporation. See Allen v. Pa. Eng’g Corp., 102 F.3d 194, 199 (5th Cir.1996). The judgment is AFFIRMED, essentially for the reasons given by the district court. Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir. R. 47.5.4.
