What do you think about this case? Might it go all the way to the Supreme court?
I haven't had time to read the recently filed Conti brief yet, but if you mean the U.S. Supreme Court, I think there is virtually no chance the Supreme Court hears this case. The key issues in this case are questions of state tort law, which the U.S. Supreme Court does not review. Even if there were an important federal consitutional question at stake, the chances of any state court case making it to the Supreme Court are incredibly small.
I think there is a good chance that the California Supreme Court hears the case, however - especially if Conti wins at the appellate level.
