(1) Where an enactment confers a power or imposes a duty, the power may be exercised and the duty shall be performed from time to time, as occasion requires.
(2) Where an enactment confers a power to make any statutory instrument the power shall be construed as including power, exercisable in the like manner and subject to the like consent and conditions, if any, to amend, alter, rescind or revoke that statutory instrument and to make other statutory instruments in lieu thereof; but this subsection shall not apply to an order which is not made by a rule-making authority in the exercise of a statutory power which is of a legislative character.
(3) Where an enactment empowers any person or authority to do any act or thing, all such powers shall be deemed to be also given as are reasonably necessary to enable that person or authority to do that act or thing or are incidental to the doing thereof.
(4) Where an enactment authorises or requires an act or thing to be done collectively by more than 2 persons, a majority of those persons may do that act or thing, unless any quorum fixed by that or any other enactment relating thereto has not been formed.
(5) Any power conferred by an enactment to make a statutory instrument or issue a statutory document may be exercised—
(a) either in relation to all cases to which the power extends, or in relation to all those cases subject to specified exceptions, or in relation to any specified cases or classes of case; and
(b) so as to make, as respects the cases in relation to which it is exercised—
(i) the full provision to which the power extends or any less provision (whether by way of exception or otherwise),
(ii) the same provision for all cases in relation to which the power is exercised, or different provision for different cases or classes of case, or different provision as respects the same case or class of case for different purposes of the enactment,
(iii) any such provision either unconditionally or subject to any specified condition.
(6) Where an enactment confers upon any person or authority power to make a statutory instrument, the statutory instrument so made shall be construed subject to the enactment under which it was made and so as not to exceed the power of that person or authority, to the intent that where any such statutory instrument would, but for this subsection, have been construed as being in excess of the power conferred upon that person or authority, the statutory instrument shall nevertheless be valid to the extent to which it is not in excess of that power.
(7) Where an enactment confers upon any person or authority power to make a statutory instrument, any act done under a statutory instrument so made shall be deemed to have been done under that enactment.
(8) Although a statutory instrument or a statutory document is expressed or purports to be made or issued by a person or authority under a specific enactment, it shall be deemed also to be made or issued under all powers thereunto enabling that person or authority.
(9) Where an enactment confers powers upon any person or authority to make any statutory instrument for any general purposes and also for any special purposes incidental thereto the enumeration of the special purposes shall not be construed as derogating from the generality of the power conferred with respect to the general purposes.
(10) Where an enactment confers a power to make any statutory instrument—
(a) there may be annexed to a contravention of that statutory instrument a punishment by way of a fine not exceeding $100 or imprisonment for a term not exceeding 3 months or both;
(b) an offence against that statutory instrument shall be punishable on summary conviction.
