9-0 reversal on forum selection

In a 9-0 opinion, the Supreme Court reversed a Fifth Circuit panel about the enforcement of a forum selection clause.  Atlantic Marine Construction v. U.S. District Court for the Western District of Texas, 571 U.S. ___ (December 3, 2013).  The panel opinion questioned enforceability when the district of suit was otherwise proper under the federal venue statutes; a strong dissent by Judge Catharina Haynes argued otherwise. The Supreme Court endorsed her position: “When the parties have agreed to a valid forum-selection clause, a district court should ordinarily transfer the case to the forum specified in that clause.  Only under extraordinary circumstances unrelated to the convenience of the parties should a §1404(a) motion be denied. And no such exceptional factors appear to be present in this case.”  Procedurally, while the Supreme Court noted in its introduction that the case arose in a mandamus context, it nowhere discusses how that posture affects the analysis — a significant point that divided the Fifth Circuit’s recent en banc vote in the case of In re Radmax.
