Before you appeal a 12(b)(1) dismissal for lack of subject matter jurisdiction to the Fourth Circuit Court of Appeals, ask yourself: Am I really sure this is a jurisdiction issue? Should we be debating a 12(b)(6) motion instead?
That moment of reflection could save you the embarrassment of an appellate court's admonishment that you don't know the "fundamental difference" between 12(b)(1) and 12(b)(6) motions.
The attorneys in a recent Jones Act appeal, no doubt, wish they had paused to consider that issue after the Fourth Circuit criticized both the parties in this appeal and the district court for misunderstanding the basics of subject matter jurisdiction.
