Here is an interesting case from Missouri:
In Rodgers v. Vilsack, (E.D. Missouri July 23, 2015), a participant in the federal Wetlands Reserve Program challenged the United States' decision to fine him for conservation easement violations.
The Wetlands Reserve Program, a Department of Agriculture program administered by the Natural Resources Conservation Services (NRCS) in conjunction with state and local agencies, pays landowners to encumber their land with conservation easements with the goal of protecting and enhancing wetlands. Rodgers owns land that was formerly strip mined 3500 of the 6200 acres). In 1998, he received $1,119,00 for a conservation easement held by the United States. Although not a WRP expert, it is my understanding that sometimes the NRCS tells the landowners what restoration projects to undertake and sometimes the NRCS (or related state/local agency) actually does the restoration itself.
I don't have a copy of the conservation easement itself, but we can glean some facts from the opinion. Rodgers claims that the NRCS restoration projects were faulty. He asserts that there were significant design flaws and in attempt to improve the habitat and wetlands on his land, he both created some dams and cut down some trees. NRCS fined him for both of these activities as being prohibited by the conservation easement. Rodgers, appearing pro se, also stated that NRCS gave him permission to undertake these activities.
The United States brought a motion to dismiss for lack of jurisdiction because the United States has not waived its sovereign immunity for actions of this type. So many interesting things to think about here.
