In Mitchell v. King, 169 Conn. 140, 363 A.2d 68 (1975), the Supreme Court held that General Statutes (Rev. to 1975) 10-234 had unconstitutionally authorized the defendant, a board of education, to expel disruptive students. Id., 144-45. The statute provided that "the board of education of any town may expel from school any pupil . . . who after a full hearing is found guilty of conduct inimical to the best interests of the school." Id., 141 n.1. The court concluded that the meaning of "inimical to the best interests" was "virtually unlimited" and did not sufficiently guard against arbitrary agency action. Id., 144.
