(a) The Governor is authorized, by proclamation, to designate and appoint one or more legal holidays, which shall include at a minimum the legal holidays designated in § 1-4, to be known as bank and credit union holidays, to be observed throughout this state, or to be observed in a certain county or town, or counties or towns, as specified in such proclamation. During such holiday period all banking and credit union transactions within the area in which such holiday is declared shall be suspended, except that the commissioner, with the approval of the Governor, may prescribe such conditions and restrictions for the conduct of banking and credit union business during such holiday period and within the area in which such holiday is declared as may appear to the commissioner to be in the best interest of the public. On one banking day that immediately precedes or follows any bank and credit union holiday, a bank or credit union may close any of its offices on its own initiative. Each such bank or credit union that closes an office on its own initiative shall provide the commissioner with forty-five-day advance notice of the date the office will be closed and shall post notice in the affected office for thirty days prior to the date such office will be closed.

(b) The commissioner may authorize the closing of all banks or Connecticut credit unions in this state or all banks or Connecticut credit unions in any specified towns or counties or any office of any bank or Connecticut credit union whenever it appears to the commissioner that such action is required as a result of an emergency, or for good cause shown.

(c) A bank or Connecticut credit union may close any office located on a college or university campus or in a building of an educational institution during any period when the college, university or educational institution is not in regular session; provided the bank or Connecticut credit union shall give notice to the commissioner in advance of its intent to effect such closings of such an office.

(d) A bank or Connecticut credit union may close any office on its own initiative whenever an emergency does not afford an opportunity to obtain the commissioner’s prior approval.

(e) The period of any closing pursuant to this section or pursuant to any similar provision of federal law, as well as the holidays otherwise provided by law, shall be a legal holiday, for purposes of the Uniform Commercial Code and otherwise, for the affected banks, Connecticut credit unions or offices.

(f) (1) If the commissioner determines that an emergency has affected and will continue to affect for an extended period of time one or more offices of a Connecticut bank or Connecticut credit union, or an office of an out-of-state state-chartered credit union or foreign bank that has an office in this state, either as a result of the emergency or subsequent recovery operations, the commissioner may issue an approval authorizing the bank or credit union affected to open one or more temporary offices or other facilities required for bank or credit union operations for the purpose of prompt restoration of banking or credit union services to the existing customers of the bank or credit union as the circumstances of such emergency may require. A temporary office or facility may be used to solicit and service new customers, provided such customers are located within the market area of the affected office. A temporary office or other facility may remain open only for the period specified in the commissioner’s approval, provided the commissioner may extend such period if the commissioner finds that the conditions requiring such office or facility continue to exist. The bank or credit union may convert a temporary office to a permanent office if permitted by and subject to the limitations and requirements of this title.

(2) If requested by the state or federal banking regulatory agency of an out-of-state bank or foreign bank, whose home state, as defined in § 36a-410, is Massachusetts, New Jersey, New York or Rhode Island, or an out-of-state state-chartered credit union whose main office is located in Massachusetts, New Jersey, New York or Rhode Island, that does not have an office in this state, and such home state or main office state is experiencing an emergency, the commissioner may issue an order authorizing such bank or credit union to open one or more temporary offices or other facilities in this state for the purpose of prompt restoration of banking or credit union services to the existing customers of the bank or credit union, as the circumstances of such emergency may require. A temporary office or facility may be used to solicit and service new customers, provided such customers are located outside this state. A temporary office or facility opened under the authority of this subsection may remain open only for the period specified in the commissioner’s approval, provided the commissioner may extend such period on a finding that the conditions requiring such office or facility continue to exist. The bank or credit union may convert a temporary office to a permanent office if permitted by and subject to the limitations and requirements of this title.

(3) To further rapid restoration of banking and credit union services after an emergency, the commissioner may temporarily waive or suspend statutory or regulatory requirements that threaten to impede recovery and restoration of financial services. For purposes of this subdivision, “temporarily” means a period of time not exceeding ninety days.

(4) For purposes of this subsection, “office” means: (A) In the case of a Connecticut bank, a “branch”, “limited branch” or “mobile branch”, as defined in § 36a-145, (B) in the case of a foreign bank, a state branch, state agency or representative office, (C) in the case of an out-of-state bank, a “branch” as defined in § 36a-410, and (D) in the case of a Connecticut credit union or out-of-state state-chartered credit union, a “branch” as defined in § 36a-435b.

(g) For purposes of this section, an emergency includes conditions arising from shortages of fuel, housing, food, transportation or labor, or arising from enemy action or threat of enemy action, from fire or other casualty, from robbery or other crime, from riot or threat of riot, or from extreme weather conditions.
