12(b)(6)
From Conservapedia
A 12(b)(6), named after the subsection of the Federal Rules of Civil Procedure on which it is based, is a motion that is filed by a defendant in the opening stages of a Federal civil case. The motion declares that there is a "failure to state a claim upon which relief can be granted," or in other words, even assuming the allegations made by the plaintiff are true, there is no legal basis for relief.
