Lawsuits filed on behalf of hundreds of Gulf Coast hurricane victims who were housed in formaldehyde-laden trailers should not be able to pursue their claims as a class action, a federal judge has ruled. In a 50-page ruling, District Judge Kurt Engelhardt found that the individual claims were too dissimilar to pursue as a class action. Attorneys for the plaintiffs had argued that class status would be the most efficient means to resolve claims against dozens of trailer manufacturers and spanning several states.
