Last week, the Federal Circuit issued its opinion in Memmer v. United States, a case we have been following because it attracted an amicus brief. In this case, Memmer appealed a decision by the Court of Federal Claims concerning a Notice of Interim Trail Use issued by the Surface Transportation Board. In the appeal, Memmer challenged the lower court’s decision that “the duration of the taking lasted as long as the railroad’s abandonment authority existed.” The United States cross-appealed to argue that the lower court “erred in holding that Appellants’ property was taken,” and in the alternative to argue that the takings concluded when the Notice of Interim Trail expired, resulting in a shorter period of time than the lower court found. In an opinion authored by Judge Schall and joined by Judges Lourie and Reyna, the Federal Circuit vacated-in-part and remanded-in-part the lower court’s decision. This is our opinion summary.
