The September 23 issue of "After Katrina Legal News," a newsletter published by the New Orleans-based firm Phelps Dunbar, is online here. Included is this rundown of Katrina Lawsuits:
The first of what is expected to be a multitude of lawsuits relating to Hurricane Katrina have been filed. The Attorney General of Mississippi has sued numerous insurance companies in state court seeking to void exclusions in property casualty insurance policies. Private class action law suits have been filed in Louisiana seeking declaratory judgment that damages caused by waters entering New Orleans because of breaches in the levee system are covered by homeowner insurance policies. A federal class action suit has been filed against oil and gas pipeline companies and oil and gas exploration companies for damages caused to Louisiana's wetlands by the creation of pipeline and access canals, which allegedly contributed to destruction caused by Hurricane Katrina. Class action suits have been filed against oil companies and oil well operators relating to some of the 44 reported oil spills caused by the storm, including five spills classified by the Coast Guard as "major" (over 100,000 gallons), and four spills classified as "medium" (10,000 to 100,000 gallons).
Martin Grace has some thoughts on the suit brought by the Mississippi AG, here and here. The Wall Street Journal editorial page calls it a "Category 5 Lawsuit." The website of the Mississippi AG's Office includes a Katrina-related links page that covers the suit.
