A new lawsuit arguing the merits of the Treasury net worth sweep was filed in Michigan, while other cases continue to hang in the balance in various phases of discovery. Michael Rop, Stewart Knoepp and Alvin Wilson v. the Federal Housing Finance Agency was filed this month by three shareholders who want the court to vacate the third amendment to the preferred stock purchase agreement and declare the structure of the Federal Housing Finance Agency unconstitutional.According to court documents, the trio is looking to challenge “both past and ongoing abuses of power by a federal agency that operates wholly outside of the system of limited and divided government established by the constitution.”
