or, rather, the FACT of it's ruling. Say, Reilly, what was the ruling breakdown of Pico since, apparently, THAT seems to meet your precedent criteria?
Actually, Pico was also a crazy case. The First Amendment must bring this out in the justices.
It came up in the context for determining whether the plaintiffs could even sue on the basis of a school removing books. The Appeals Court determined that it wasn't clear why the books were rejected and the District Court should have a full trial to figure that out first.
Three justices (Brennan, Marshall and Stevens) said the plaintiffs could sue, and that the First Amendment applies to studens in school, but must be construed according to the educational mission of the school In the present case, the determined that this prevents school libraries from removing books for political or partisan reasons.
One Justice (Blackmun) wrote a separate opinion saying that the Plaintiffs could sue and stressing that it is important that political ideas were at issue, and hence the 1st Amendment was implicated.
One Justice (White) said that there was enough factual evidence about improper motives of school officials that a full trial was warranted, and if he needed to discuss the First Amendment, he would wait to do after the full trial (as it could be settled beforehand, or it could be determined at trial that the school board wasn't acting for political reasons, making the whole question moot). What a copout.
The rest of the justices dissented for various reasons, including most prominently, the fact that school boards are state organs with a separate educational mission and it shouldn't be the role of federal courts to intrude on this mission.
So... no reasoning got 5 votes, so the only thing that really counts is that the case got to be heard before a full court. No final ruling was held on the applicability of the first amendment.
