What is the test for determining the constitutional validity of a law that restricts access to a student's privacy?

Determining the constitutional validity of a law having such paradoxical and potentially serious effects is no easy task. Indeed, this case presents a confluence of state constitutional issues of great complexity and delicacy. We must adjudicate rights under the state constitutional right of privacy in the always thorny context of abortion, rendered all the more volatile and challenging because the rights at issue are those of adolescents rather than adults. And we must do so using a test newly established in Hill v. National [16 Cal.4th 361] Collegiate Athletic Assn. (1994) 7 Cal.4th 1, 26 Cal.Rptr.2d 834, 865 P.2d 633. Without question this is one of the most important and difficult cases we have decided in many years.
