R.I. Gen. Laws § 7-1.2-810: Action by directors without a meeting.

Unless otherwise provided by the articles of incorporation or bylaws, any action required by this chapter to be taken at a meeting of the directors of a corporation, or any action which may be taken at a meeting of the directors or of a committee, may be taken without a meeting if all of the directors, or all of the members of the committee, as the case may be, consent thereto in writing or by electronic transmission, before or after the action, and the writing or writings or electronic transmission or transmissions are filed with the minutes of proceedings of the board or committee. The consent has the same effect as a unanimous vote for all purposes, and that may be stated in any certificate or other document filed with the secretary of state.
