Without even looking, ...

... I’ll take a wild guess that this West headnote comes from one of Judge Selya’s opinions:

When interpreting one statute by reference to subsequently enacted statute, rationale for later statute cannot automatically be transformed by some thaumaturgical feat of rhetorical prestidigitation into rationale for preexisting statute. Denny v. Westfield State Coll., 880 F.2d 1465 (1st Cir. 1989).

When I get to work tomorrow, I’ll look it up to see if my guess was correct.
