In Allen v. Toms River Regional Board of Educ., 233 N.J. Super. 642, 647, 559 A.2d 883 (Law Div.1989), the Court summarized the appellate decisions dealing with those instances in which conflicts left the public body with inadequate membership to constitute a quorum, and identified cases in which the court found the circumstances dictated that members in conflict should be permitted to sit. Generally speaking, the doctrine of necessity is utilized when a pressing public need exists, and it would be detrimental to the public's well-being to bar the disqualified members from participating in a vote.
