The corporate existence begins on the issuance of the certificate of incorporation. That certificate is conclusive evidence that all precedent conditions required to be performed by the incorporators have been satisfied and that the corporation has been incorporated. Issuance does not affect the right of the state to bring a proceeding to cancel or revoke the certificate or for involuntary dissolution of the corporation. The doctrines of de jure compliance, de facto corporations, and corporations by estoppel are abolished.
