2006In this assignment, defendants argue that the trial court erred in finding that plaintiffs satisfied the numerosity requirement and rely heavily upon the first circuit's decision in Hampton v. Illinois Central Railroad Co., 98-0430 to 98-435 (La.App. 1 Cir. 4/1/99) , 730 So.2d 1091 in support of their contention.

2004In Hampton , 98-0430 at p. 11, 730 So.2d at 1096 , we similarly observed that in a mass tort case, a trial court cannot properly determine whether the numerosity requirement has been met without first determining the physical area of the mass tort.
