The "rule of unanimity"--a requirement that all defendants join a notice of removal, is not expressed verbatim in secs. 1441 or 1446 of Title 28. It is a judicial interpretation of the phrase "defendant or defendants." See Harper v. AutoAlliance International, Inc., 392 F.3d 195 (6th Cir. 2004); Loftis v. United Parcel Service, Inc., 342 F.3d 509 (6th Cir. 2003).
