11.—The following provisions shall apply and have effect in relation to the construction of every Act of the Oireachtas and of every instrument made wholly or partly under any such Act, that is to say:—

(a) Singular and plural. Every word importing the singular shall, unless the contrary intention appears, be construed as if it also imported the plural, and every word importing the plural shall, unless the contrary intention appears, be construed as if it also imported the singular;

(b) Masculine and feminine. Every word importing the masculine gender shall, unless the contrary intention appears, be construed as if it also imported the feminine gender;

(c) Person. The word “person” shall, unless the contrary intention appears, be construed as importing a body corporate (whether a corporation aggregate or a corporation sole) and an unincorporated body of persons as well as an individual;

(d) Time. Every word or expression relating to time and every reference to a point of time shall, unless the contrary intention appears, be construed as relating or referring to Greenwich mean time, but subject to the provisions of any enactment whereunder the time in Ireland differs from Greenwich mean time during a specified period;

(e) Distance. Every word or expression relating to the distance between two points and every reference to the distance from or to a point shall, unless the contrary intention appears, be construed as relating or referring to such distance measured in a straight line on a horizontal plane;

(f) Citations. Every description of or citation from any statute, instrument, or other document shall, unless the contrary intention appears, be construed as including the word, sub-section, section, or other portion mentioned or referred to as forming the beginning or as forming the end of the portion comprised in the description or citation or as being the point from which or to which such portion extends;

(g) Marginal notes. No marginal note placed at the side of any section or provision to indicate the subject, contents, or effect of such section or provision and no heading or cross-line placed at the head or beginning of a Part, section or provision or a group of sections or provisions to indicate the subject, contents, or effect of such Part, section, provision, or group shall be taken to be part of the Act or instrument or be considered or judicially noticed in relation to the construction or interpretation of the Act or instrument or any portion thereof;

(h) Periods of time. Where a period of time is expressed to begin on or be reckoned from a particular day, that day shall, unless the contrary intention appears, be deemed to be included in such period, and, where a period of time is expressed to end on or be reckoned to a particular day, that day shall, unless the contrary intention appears, be deemed to be included in such period;

(i) Offences by corporations. References to a person in relation to an offence (whether punishable on indictment or on summary conviction) shall, unless the contrary intention appears, be construed as including references to a body corporate.
