Conn. Gen. Stat. § 33-912: Amendment of special charter.

(a) Amendment of a special charter by the General Assembly shall require acceptance by the corporation if and to the extent provided in the act of amendment.

(b) The certificate of incorporation of a specially chartered corporation may be amended by its shareholders for the purposes and in the manner provided by sections 33-600 to 33-998, inclusive, for corporations incorporated under said sections except that its certificate of incorporation as so amended shall not authorize it to engage in any business or to carry on its business in any area unless either (1) it could be so authorized under section 33-645, or (2) it was so authorized by its certificate of incorporation prior to such amendment. A specially chartered corporation the name of which does not contain the words “corporation” or “company” or “incorporated” or “limited” or “Societa per Azioni” or an abbreviation of one of such words may amend its certificate of incorporation pursuant to this subsection without changing its name.

(c) A restated certificate of incorporation adopted by a specially chartered corporation need not, in order to preserve the provisions of special acts of the legislature setting forth its franchises, whether of a public or a private nature, the nature of its business, and its special rights, privileges and immunities, recite such provisions.
