Sec. 31-1. Definition.

A public school fraternity, sorority or secret society, in this Article means any organization, composed wholly or in part of public school pupils, which seeks to perpetuate itself by taking in additional members from the pupils enrolled in such school on the basis of the decision of its membership rather than upon the free choice of any pupil in the school who is qualified by the rules of the school to fill the special aims of the organization.
