(1)This Act, except such of the provisions thereof as are expressly restricted to the United Kingdom, shall extend throughout His Majesty's dominions : Provided that it shall not extend to a self-governing dominion, unless declared by the Legislature of that dominion to be in force therein either without any modifications or additions, or with such modifications and additions relating exclusively to procedure and remedies, or necessary to adapt this Act to the circumstances of the dominion, as may be enacted by such Legislature.
(2)If the Secretary of State certifies by notice published in the London Gazette that any self-governing dominion has passed legislation under which works, the authors whereof were at the date of the making of the works British subjects resident elsewhere than in the dominion or (not being British subjects) were resident in the parts of His Majesty's dominions to which this Act extends, enjoy within the dominion rights substantially identical with those conferred by this Act, then, whilst such legislation continues in force, the dominion shall, for the purposes of the rights conferred by this Act, be treated as if it were a dominion to which this Act extends ; and it shall be lawful for the Secretary of State to give such a certificate as aforesaid, notwithstanding that the remedies for enforcing the rights, or the restrictions on the importation of copies of works, manufactured in a foreign country, under the law of the dominion, differ from those under this Act.
