Chap. 0460 An Act relative to the civil liability of persons owning or controlling real estate or other premises used for civil defense shelters. Whereas, The deferred operation of this act would tend to defeat its purpose, which is, in part, to relieve persons owning or controlling real estate or other premises used for civil defense purposes from civil liability under certain circumstances, and to assure adequate civil defense protection, therefore it is hereby declared to be an emergency law, necessary for the immediate preservation of the public convenience. Be it enacted, etc., as follows: Chapter 639 of the acts of 1950 is hereby amended by inserting after section 12 the following section: - Section 12A. Any person owning or controlling real estate or other premises who voluntarily and without compensation grants to a city or town a license or privilege, or otherwise permits a city or town, to inspect, designate and use the whole or any part or parts of such real estate or premises for the purpose of sheltering persons during an actual, impending or mock enemy attack shall, together with his successors in interests, if any, not be civilly liable for negligently causing the death of, or injury to, any person, or for loss of, or damage to, the property of such person on or about such real estate or premises under such license, privilege or other permission; and section fifteen of chapter one hundred and eighty-six of the General Laws shall not be deemed to apply to any agreement granting such license or privilege or to such other permission, whether such agreement is executed, or such other permission is given, before or after the effective date of this section. Approved June 80, 1951.
