Last week saw the birth of the seven billionth current human on the planet. This week sees us comment on the parallel claim exception to Riegel preemption for what feels like the seven billionth time. It puts us in mind of Nietzsche's theory of the eternal return, where everything we've done we'll do again an infinite number of times. Really? We've got to go through that junior prom again, with all the plaid bell-bottoms and the awful Peter Frampton "tribute" band playing "Show Me the Way" as we fought off the effects of smuggled-in Southern Comfort?

We wish courts would do a better job of showing us the way on the parallel claim exception. Is it possible that the parallel claim exception is poorly conceived and poorly described, thereby prompting plaintiffs to parade various attempts to plead around it, leading to courts issuing rulings on the issue that are inconsistent and opaque? Yes, it is. Some parallel claims decisions have been reasonably coherent; others have blessed complaints resembling mackerels in the moonlight -- they shine, they stink. Bausch is an example of the latter, and yet the Seventh Circuit waved it by. We'll not regale you again with our Why We Hate Bausch litany, though the U.S. Supreme Court's recent refusal to review it led to a marathon teeth-grinding session here on the West Bank of the Schuykill.
