devil's umbrella

Poison hemlock or water hemlock, Conium and Cicuta respectively. They are both deadly poisonous umbelliferous plants. The poisons in these plants act differently: Poison hemlock (the hemlock of Socrates' time) contains coniine, which causes ascending paralysis and suffocation, and water hemlock contains cicutoxin, which causes violent convulsions and nervous system collapse.

That's a devil's umbrella, Johnny. Don't even THINK of picking it!

Umbrella Case

A term used describe one case which proceeds (or receives the most attention) to establish new case law or precedent, but there are (many) other cases with similar facts that will be impacted by the court's decision in the "umbrella" case.

Brown v. Board of Eduction could be considered an "umbrella case", in that it established new law and prevented schools from segregating on the basis of race, but at the time of Brown, numerous other school segregation cases were also in the judicial process, and these cases fell under the "umbrella" of the decision in Brown.
