Unless this case is appealed, it is not a precedent outside Pennsylvania.
And just where is your law degree from?
It's a precedent everywhere. It's only binding precedent in that particular district in PA, but it is quite pursuasive in any jurisdiction. It is an efficient compendium of the current law and of the background of intelligent design. There isn't a judge in the country that would not have to at least analyze and deal with Dover in an intelligent design case. It would be hard for a judge to come up with a legally sound reason to ignore Dover.
