A federal appeals court has ruled in favor of Fannie Mae and Freddie Mac, overturning a lower court ruling that the counties and state of Michigan were entitled to collect local real estate transfer taxes from the two government-sponsored enterprises. This week’s unanimous ruling by a three-judge panel from the U.S. Court of Appeals for the Sixth Circuit said the lower court is not in a position to second-guess Congress by creating exemptions to tax statutes. “The statutes at issue here plainly state that the defendants are exempt from ‘all taxation,’” the court ruled. In June 2011, Oakland and Genesee counties each filed suit claiming Fannie and Freddie recorded deeds and other conveyances without paying the Michigan Transfer Tax.
