This morning, a class (er, "caucus"?) of Iowa consumers and businesses announced their settlement of an antitrust case against Microsoft, according to the NYT. The class sought to recover overcharges of up to $453 million. Iowa declined to accept its part of an earlier settlement and had started trying its case against Microsoft. The en banc D.C. Circuit previously upheld a judgment against Microsoft for antitrust violations in the federal government’s civil case. United States v. Microsoft Corp., 253 F.3d 34 (D.C. Cir. 2001) (per curiam).
