In re Katrina Canal Breaches Litigation 

Date: 18 November 2009

Court: United States District Court, Eastern District of Louisiana

Citation: 647 F. Supp. 2d 644

Short summary  

Hundreds of thousands of homes were lost in Hurricane Katrina and most homeowners’ insurance policies excluded them from compensation. This led many victims of Katrina to sue the United States government under the Federal Tort Claims Act (FTCA), alleging the U.S. Army Corps of Engineers (Corps) failed to properly maintain the Mississippi River Gulf Outlet, leading to the breach of one of New Orleans’ levees. The District Court held the U.S. was not immune from such a suit and held the Corps liable to some of the plaintiffs. This judgment was later reversed by the Fifth Circuit Court of Appeal, on the grounds that the U.S. has sovereign immunity under the FTCA from such claims.

Weight of decision  

The ruling by the Eastern District of Louisiana District Court, insofar as its logic was affirmed by the Court of Appeals, holds precedential authority in the Fifth District (Texas, Louisiana, Mississippi) and persuasive authority in other U.S. Circuits (see, e.g., favourable analysis in the Northern and Central Districts of Illinois). However, this ruling has subsequently been read narrowly by the same Eastern District court (holding there must be “ample record evidence” the government neglected its duty to maintain waterways implicated in flooding).  

Key facts 

Under the Federal Tort Claims Act (FTCA; 28 USC §171), the U.S. government is immune from liability if its (in)action can be classified as a discretionary function (i.e., a policy decision left to an agency via legislation) rather than a specifically delegated ministerial duty not executed with due care.  

Under the Flood Control Act (FCA; 33 USC §702c), the U.S. government is immune from liability for damage stemming from its flood control efforts.  

The U.S. Army Corps of Engineers’ (Corps) were charged with construction, maintenance, and operation of the Mississippi River Gulf Outlet (MRGO), a navigational channel. This mandate was separate from the Corps’ efforts directed at flood control and levee construction and maintenance in southern Louisiana.  

Over decades, the Corps failed to prevent the MRGO from expanding well beyond its intended width, destroying wetlands which are protective against storm surges. This in contravention of the National Environmental Policy Act and despite repeated internal and external reports warning of the danger of not shoring up the MRGO’s banks. This failure was a substantial cause of the breach of a levee, leading to catastrophic flooding of St. Bernard parish in the New Orleans metropolitan area.  

Previous instances  

This case relies on Central Green v. United States (U.S. Supreme Court, 2001), wherein Justice Stevens held that the U.S. was not entitled to immunity under the FCA from damage caused by any and all flood waters. Instead, the government must show that flooding is connected with projects serving a primarily flood control purpose, in order for mismanagement of such projects to grant immunity.
