Any bank, savings bank, trust company, safe deposit company, building-loan association, national banking association, or federal savings and loan association doing business within the state of Rhode Island, or any branch or office of the institution, may remain closed on any Saturday or Saturdays upon the adoption of a resolution to close by the board of directors or their board of trustees and upon filing a copy of the resolution as required in this section. The resolution is deemed effective for the purposes of this section and § 25-1-4 only when a copy certified by the proper officer of the institution is filed in the office of the director of business regulation, and the resolution remains in full force and effect until a copy of a later resolution, certified in the same manner, terminating the prior resolution, is filed in the office of the director of business regulation.
