This publication incorporates final legislative actions taken during the 2009-10 legislative cycle. Legislation adopted after August 1, 2009, interpretations incorporated by the Legislative Review/Interpretations Committee, modifications of wording and editorial revisions are set off by a gray background and also include an adoption or revision date. Divisions I, II and III each have a separate Manual that contains legislation specific to the applicable division and does not contain legislation pertaining only to one or both of the other divisions. However, legislation that includes references to one or both of the other divisions will appear in its entirety. In addition, since each division's Manual does not contain legislation specific to the other division(s), some bylaws may have gaps in the numbering sequence. Articles 1 through 6 are the constitution, which consists of information relevant to the purposes of the Association, its structure, its membership and legislative-process information, and the more important principles for the conduct of intercollegiate athletics. Articles 10 through 23 are the operating bylaws, which consist of legislation adopted by the membership to promote the principles enunciated in the constitution and to achieve the Association's purposes. Articles 31 through 33 are administrative bylaws, which set forth policies and procedures for the implementation of (a) the general legislative actions of the Association, (b) the NCAA championships and the business of the Association, (c) the Association's enforcement program and (d) the Association's athletics certification program. These administrative bylaws may be adopted or modified by the Division I Board of Directors or Legislative Council for the efficient administration of the activities that they govern. These same bylaws also may be amended by the membership through the regular legislative process. (Contains 18 figures.)
