PER CURIAM.
The judgment of the Law Division is affirmed substantially for the reasons set forth in the opinion of Judge Demos, which was approved in Rost v. Fair Lawn Bd. of Ed., 137 N.J. Super. 76 (App.Div. 1975).
In view of our disposition of the matter, we need not consider the issue of informal or substantial compliance which was also raised on this appeal.
Affirmed.
