The Use of "Childish" in Supreme Court Opinions

I'm now writing my article on the military draft (working title is "Conscription's Constitution"). When the Supreme Court upheld the constitutionality of the World War I draft in a not-so-great opinion, the Court described one of the arguments on the other side as "childish." This caught my attention. Did any other case do this?

The answer is no. There are some cases that describe children as childish or describe a person's behavior that way. But no other opinion calls an argument childish. Though check back with me at the end of the month. That could change.
