Newbold v. Kinder Morgan SNG Operator, No. 22-30416 (5th Cir. 2023)
Annotate this Case
Two years after an unfortunate single-boat accident, one of the boat’s two occupants died as a result of his injuries. The boat in which he was a passenger had struck a warning sign that was totally submerged at the time of the allision between the boat and sign. His estate and survivors sued the companies responsible for the sign in question. The district court granted summary judgment to the Defendants on the ground that the incident occurred on water governed by Louisiana law rather than federal. The parties agreed that if Louisiana law governs, the claims are barred. At issue in this appeal is whether or not the allision occurred in “navigable” waters such that federal law governs
The Fifth Circuit affirmed. The court explained that navigational servitude relates to actualities – “the waters below the ordinary high-water mark,” “the line of the shore,” and so forth, id. – rather than potentialities. Should the Corps permanently flood the Refuge, the water there would likely be navigable. But as the parties agree that the Corps has not, in fact, permanently flooded the refuge, the water may not be said to be navigable under this theory. Further, the unvegetated channel establishes the ordinary high-water mark of the Bayou; water outside of that channel is not navigable. Moreover, Plaintiffs here failed to present even slight evidence concerning a commercial purpose for the channel in question. Accordingly, the court found that the water in which the allision occurred was not navigable and summary judgment was proper.
