Bylaws . .  . 

are the operating rules of a corporation. They are adopted by the company's board of directors and govern such things as the election of directors, the size of the board of directors, and the election and function of each of the company's officers. Bylaws can normally be amended by the company's directors and are more easily changed than the company's charter, which can only be amended with shareholder approval. See: Charter, Directors' Indemnities.
