One might look with suspicion upon a court that initially issues a unanimous decision in favor of one litigant and then subsequently reverses course entirely and renders a unanimous decision for the other litigant. Yet that’s exactly what the U.S. Court of Appeals for the Fifth Circuit did in In re Katrina Litigation.

In March, a three-judge panel ruled — unanimously — that the U.S. Army Corps of Engineers was not entitled to immunity under the Federal Tort Claims Act with respect to damages resulting from flooding in the wake of Hurricane Katrina allegedly arising out of negligent construction and maintenance of the Mississippi River Gulf Outlet.
