Demahy, slip op. at 8. Moreover, the court held that even if Foster were undercut, that was a Maryland law decision, and Louisiana law wouldn't allow the claims anyway. Id. at 8-9.
The court also addressed generic preemption (yet again), but mostly on the "mandate rule" that plaintiff didn't have any other claims before - so go away, plaintiff. Nonetheless, to cover all its bases, the court said that all the purported "other" claims were either disguised warning claims (preempted) or design claims (which are also preempted). Demahy, slip op. at 12-13 (with nice string-cite footnotes).
Stick a fork in Demahy - it's done.
