Mealey's (April 6, 2020, 10:39 AM EDT) -- NEW ORLEANS — A federal judge in Louisiana on April 1 denied the federal government’s motion for partial summary judgment on the amount it seeks to recover in an Oil Pollution Act of 1990 (OPA) case over a 2015 oil spill in the Mississippi River, finding that a defense expert’s opinion that $631,228.74 was an excessive amount to clean up the 378-gallon spill creates a triable issue (United States v. E.R.R. LLC, et al., No. 19-2340, E.D. La., 2020 U.S. Dist. LEXIS 57985)....
