“Act” means— | ||||||||||||||||||||||||||||||||||||
(a) an Act of the Oireachtas, and | ||||||||||||||||||||||||||||||||||||
(b) a statute which was in force in Saorstát Éireann immediately before the date of the coming into operation of the Constitution and which continued in force by virtue of Article 50 of the Constitution; | ||||||||||||||||||||||||||||||||||||
“enactment” means an Act or a statutory instrument or any portion of an Act or statutory instrument; | ||||||||||||||||||||||||||||||||||||
“repeal” includes revoke, rescind, abrogate or cancel; | ||||||||||||||||||||||||||||||||||||
“statutory instrument” means an order, regulation, rule, bye-law, warrant, licence, certificate, direction, notice, guideline or other like document made, issued, granted or otherwise created by or under an Act and references, in relation to a statutory instrument, to “made” or to “made under” include references to made, issued, granted or otherwise created by or under such instrument. | ||||||||||||||||||||||||||||||||||||
(2) For the purposes of this Act, an enactment which has been replaced or has expired, lapsed or otherwise ceased to have effect is deemed to have been repealed. | ||||||||||||||||||||||||||||||||||||

(c) the Interpretation Act 1937 ; | ||||||||||||||||||||||||||||||||||||
(d) the Interpretation (Amendment) Act 1993 . | ||||||||||||||||||||||||||||||||||||
(2) (a) The repeal by this Act of an Act which assigns a meaning to a word or expression in another enactment does not affect the meaning so assigned if— | ||||||||||||||||||||||||||||||||||||
(i) in the absence of that meaning in this Act, or | ||||||||||||||||||||||||||||||||||||
(ii) by the application to the other enactment of the meaning assigned by this Act to the same or a similar word or expression, | ||||||||||||||||||||||||||||||||||||
the other enactment would be changed in intent or become unclear or absurd. | ||||||||||||||||||||||||||||||||||||
(b) The repeal by this Act of an Act which provides for any matter (other than a matter to which paragraph (a) relates) in another enactment does not affect the matter so provided for if— | ||||||||||||||||||||||||||||||||||||
(i) in the absence of that matter being provided for in this Act, or | ||||||||||||||||||||||||||||||||||||
(ii) by the application to the other enactment of a matter provided for by this Act which corresponds to a matter provided for in the repealed Act concerned, | ||||||||||||||||||||||||||||||||||||
the other enactment would be changed in intent or become unclear or absurd. | ||||||||||||||||||||||||||||||||||||

(2) The provisions of this Act which relate to other Acts also apply to this Act unless the contrary intention appears in this Act. | ||||||||||||||||||||||||||||||||||||
PART 2 Miscellaneous Rules | ||||||||||||||||||||||||||||||||||||

(b) that on a literal interpretation would be absurd or would fail to reflect the plain intention of— | ||||||||||||||||||||||||||||||||||||
(i) in the case of an Act to which paragraph (a) of the definition of “Act” in section 2 (1) relates, the Oireachtas, or | ||||||||||||||||||||||||||||||||||||
(ii) in the case of an Act to which paragraph (b) of that definition relates, the parliament concerned, | ||||||||||||||||||||||||||||||||||||
the provision shall be given a construction that reflects the plain intention of the Oireachtas or parliament concerned, as the case may be, where that intention can be ascertained from the Act as a whole. | ||||||||||||||||||||||||||||||||||||
(2) In construing a provision of a statutory instrument (other than a provision that relates to the imposition of a penal or other sanction)— | ||||||||||||||||||||||||||||||||||||
(a) that is obscure or ambiguous, or | ||||||||||||||||||||||||||||||||||||
(b) that on a literal interpretation would be absurd or would fail to reflect the plain intention of the instrument as a whole in the context of the enactment (including the Act) under which it was made, | ||||||||||||||||||||||||||||||||||||
the provision shall be given a construction that reflects the plain intention of the maker of the instrument where that intention can be ascertained from the instrument as a whole in the context of that enactment. | ||||||||||||||||||||||||||||||||||||
Construing provisions in changing circumstances. | 6.—In construing a provision of any Act or statutory instrument, a court may make allowances for any changes in the law, social conditions, technology, the meaning of words used in that Act or statutory instrument and other relevant matters, which have occurred since the date of the passing of that Act or the making of that statutory instrument, but only in so far as its text, purpose and context permit. | |||||||||||||||||||||||||||||||||||

(b) in the case of an Act of the Oireachtas of Saorstát Éireann, the signed text of such law as enrolled for record in the office of such officer of the Supreme Court of Saorstát Éireann as Dáil Éireann determined pursuant to Article 42 of the Constitution of the Irish Free State (Saorstát Éireann), | ||||||||||||||||||||||||||||||||||||
(c) in the case of any other Act, such text of that Act as corresponds to the text of the Act enrolled in the manner referred to in paragraph (a) or (b). | ||||||||||||||||||||||||||||||||||||
