Thus, in Chappey v. Ineos USA LLC, 2009 WL 790194 (N.D. Ind. March 23, 2009), the court granted a motion do dismiss where the complaint failed to allege the supposed violation that was the basis for a "negligence per se" claim in an environmental contamination case. Here's what the court had to say:
[Plaintiff] alleges that Defendants “violated various statutes, ordinances or regulations without justification or excuse.” Defendants believe the negligence per se claim should be dismissed because no statute or regulation was identified, thus the count adds nothing to the already pled negligence count, and does not give Defendants fair notice of the basis of Plaintiff's claim. In her reply, [plaintiff] argues that she has complied by filing a short plain statement, and that Bell Atlantic [v. Twombly] does not require that a negligence per se claim reference a specific statute. . . .
Notice pleading requirements suggest that Plaintiff must plead the specific statute on which she bases her claim for negligence per se. See Bell Atlantic, 127 S.Ct. at 1964-65 (holding the complaint must describe a claim in sufficient detail to give defendant fair notice of what the claim is and the grounds upon which it rests). Here, where [plaintiff] is bringing a claim based upon specific statutes, regulations, or ordinances, it logically follows that she must plead the statute(s) upon which the claim is based. [A] . . . generic complaint that defendant violated unspecified local, state and federal statutes, guidelines and regulations does not provide fair notice of [plaintiff's] claim. Similarly, because [plaintiff] has failed to identify a specific statute, regulation, or ordinance to support her claim of negligence per se, Defendants do not have fair notice of the claim, and it should be dismissed pursuant to Federal Rule of Civil Procedure 12(b)(6).
2009 WL 790194, at *2-3 (various citations and quotation marks omitted).
Defense counsel: Chappey means you've got something to cite besides plain common sense to argue the violation claims must specifically plead what it is that the defendant allegedly violated.
Critics of Twombly/Iqbal: Chappey is an excellent example of just how much plaintiff's counsel thought they could get away with before Twombly. Don't tell us anymore that a tightening up of pleading standards wasn't long overdue.
