Appellee Schmid was arrested and charged with criminal trespass while distributing political materials on the campus of Princeton University. Schmid was not a student at Princeton University. Under University regulations then in effect, members of the public who wished to distribute materials on the campus were required to receive permission from University officials. Appellee was tried in Princeton Borough Municipal Court and on October 20, 1978, the trial judge issued an opinion convicting appellee and fining him $15 plus $10 costs. A de novo trial in the New Jersey Superior Court, Law Division, also resulted in conviction and the same fine was imposed. While appeal was pending to the Superior Court, Appellate Division, the case was certified for review by the New Jersey Supreme Court. That court invited the University to intervene and participate as a party, which it did!
The New Jersey Supreme Court reversed the judgment of conviction, holding that appellee’s rights of speech and assembly under the New Jersey Constitution had been violated.

v.
Schmid,
84 N. J. 535,
II
The State of New Jersey has filed a brief in this Court asking us to review and decide the issues presented, but stating that it'“deems it neither necessary nor appropriate to express an opinion on the merits of the respective positions of the private parties to this action.” Brief for Appellant State of New Jersey 4. Had the University not been a party to this case in the New Jersey Supreme Court and had the State filed a jurisdictional statement urging reversal, the existence of a case or controversy — and of jurisdiction in this Court— could not be doubted. However, if the State were the sole appellant and its jurisdictional statement simply asked for review and declined to take a position on the merits, we would have dismissed the appeal for want of a case or controversy. We do not sit to decide hypothetical issues or to give advisory opinions about issues as to which there are not adverse parties before us. See,

Morton,
Princeton defends its own standing and our jurisdiction on the grounds that it was a party to the case in the New Jersey Supreme Court,

that it is bound by the judgment of that

court with respect to the validity of its regulations, and that no other forum is available in which to challenge the judgment on federal constitutional grounds. We have determined, however, that we lack jurisdiction with respect to Princeton. The New Jersey Supreme Court noted that while the case was pending on appeal, the University substantially amended its regulations governing solicitation, distribution of literature, and similar activities on University property by those not affiliated with the University. 84 N. J., at 539-541, n. 2, 568,
Princeton does not claim standing on the ground that a private party may intervene and challenge the reversal of a criminal conviction of another party. See

v.
Richard D.,
So ordered.
Notes
That Princeton had standing in state court does not determine the power of this Court to consider the issue. Any determination of who has standing to assert constitutional rights is a federal question to be decided by the Court itself.
