South Dakota Swampbuster Case

"Swampbuster" is a provision, originating with the 1985 farm bill, which prohibits farmers who get farm program benefits from draining wetlands. That's the over-simplified version. This article describes a case in SD where a big partnership (brothers) receiving big bucks ($2.5 mill in 10 years) is fighting a determination by National Resource Conservation Service. There's enough description to show some of the complexities involved, though it doesn't say when the violation is said to have occurred.
