the Acts Interpretation Act, but they are expressly so made by the
Transport Workers Act itself. The object of sec. 10 of the Acts
Interpretation Act is twofold : one, to fix the date of commencement
of regulations, the other to retain the power of disallowance in
Parliament. The power to make regulations is construed, unless
a contrary intention appears, as including a power to rescind,
revoke, amend, or vary such regulations (Acts Interpretation Act 1901-
1930, sec. 33 (3) ). Therefore the power of disallowance is to ensure
the control and supervision of Parliament over regulations. But
it is argued that this control is subject to two conditions precedent :
that the regulations be laid before each House of Parliament,
and, before either House can disallow them, it must pass a resolution
of which notice has been given within fifteen sitting days after the
regulations have been laid before such House. Is this right ?
Acts passed for the purpose of enabling something to be done, and
prescribing the way in which it is to be done, may, in the language
of the cases, be absolute, or imperative, or directory only. An
absolute or imperative enactment must be obeyed or fulfilled
exactly, and, if it be neglected or contravened, the Courts of law
will treat the thing done as altogether invalid and void (Woodward
y. Sarsons (1) ). On the other hand, if the enactment be directory
only, its non-observance will not render the thing done invalid or
void. "The question," says the Judicial Committee in Montreal
Street Railway Oo. v. Normandin (2), "whether provisions in a
statute are directory or imperative has very frequently arisen in
this country, but it has been said that no general rule can be laid
down, and that in every case the object of the statute must be looked
at. . . . When the provisions of a statute relate to the perform-
ance of a public duty and the case is such that to hold null and void
acts done in neglect of this duty would work serious general incon-
venience, or injustice to persons who have no control over those
entrusted with the duty, and at the same time would not promote
the main object of the Legislature, it has been the practice to hold
such provisions to be directory only, the neglect of them, though
punishable, not affecting the validity of the acts done.' (See also
Howard v. Bodington (3).) In the present case, the object of the
