A certificate of incorporation is the functional equivalent of a corporation's constitution. The certificate goes by different names in different states. In other states it is known as the articles of incorporation or the corporate charter, or the articles of organization. All of these refer to the same document.
As the corporation's constitution, the certificate may limit or define the power of the corporation and the corporation's board of directors. Drafter's of certificates have a great deal of flexibility when drafting these documents. Although most certificates are “plain vanilla” certificates that rely almost entirely on the state corporate law default rules for limiting the power of the corporation and its directors, such a minimal approach to drafting corporate documents is not required.
For example, some corporations, like the Green Bay Packers professional football team, have highly tailored certificates of incorporation. The Green Bay Packers' certificate is available on the course website. Promoters of the Green Bay Packers corporation tailored the rights of shareholders so that no shareholder can expect to receive any portion of the profits of the Packers – those have to be donated to a charity – and that no shareholder can expect their shares of the Packers to have any resale value on a stock exchange – any attempt to transfer shares to someone other than a family member will result in the corporation redeeming the shares for pennies.
Section 101 makes it clear that the filing of a certificate of incorproation is sufficient to form a corporation. This is the essence of an enabling statute. Rather than require the state to provide permission, enabling statutes like Delaware's General Corporation Law require only a ministerial filing in order to establish a corporation and permit the corporation's promoters a high degree of freedom in the design of their internal governance mechanisms.
