The guy suing Satan (still my favorite case ever,
but this new one is moving into a tie for second
place with Pamela Anderson v. Excitement Video) is Ex
Rel Mayo, 54 F.R.D. 282.
The judge wisely
notes notes the argument that Satan is a foreign
prince, the difficulties of personal jurisdiction, the
fact that anyone suing satan would have to make it a
class action, and a trial in New hampshire where the
defendant, as plaintiff, brought a mortgage forclosure
action.)
