"The submission (as to the proper construction of
s.24(1A)(c) of the Liquor Act 1912 (NSW)) raises a question
of a type which is frequently encountered. The problem
arises whenever a judicial or executive act, or the act of a
litigant, is subjected by statute to the prior performance
of conditions. The numerous decisions in this field have
been recently reviewed by this Court: Attorney-General (NSW)
ex rel. Franklins Stores Pty. Ltd. v Lizelle Pty. Ltd.
(1977) 2 NSW LR 955 and Hatton v. Beaumont (1977) 2
NSW LR 211. The position of directory enactments has
also been expounded in an authoritative but obiter way in
Victoria v The Commonwealth [1975] HCA 39; (1975) 134 CLR 81. From
these sources we take the following propositions: (1) The
problem is to be solved in the process of construing the
relevant statute. Little, if any, assistance will be
derived from the terms of other statutes or any supposed
judicial classification of them by reference to subject
matter. (2) The task of construction is to determine whether
the legislature intended that a failure to comply with the
stipulated requirement would invalidate the act done, or
whether the validity of the act would be preserved
notwithstanding non-compliance: the Franklins Stores Pty.
Ltd. case (1977) 2 NSW LR 955, at pp 963 et seq. (3)
The only true guide to the statutory intention is to be
found in the language of the relevant provision and the
scope and object of the whole statute: Hatton v. Beaumont
(1977) 2 NSW LR 211, at p 220. (4) The intention being
sought is the effect upon the validity of the act in
question, having regard to the nature of the precondition,
its place in the legislative scheme and the extent of the
failure to observe its requirement: Victoria v. The
Commonwealth [1975] HCA 39; (1975) 134 CLR 81, at pp 179, 180. (5) It
can mislead if one substitutes for the question thus posed
an investigation as to whether the statute is mandatory or
directory in its terms. It is an invitation to error, not
only because the true inquiry will thereby be sidetracked,
but also because these descriptions have been used with
varying significations. (6) In particular, it is wrong to
say that, if a statute is couched in directory terms, the
act will be invalid, unless substantial performance is
demonstrated; the Franklins Stores Pty. Ltd. case (1977) 2
NSW LR 955, at pp 965 et seq. A statute which, on its
proper construction, does not nullify the act in question,
even for total non-observance of the stipulation, is also
described as directory in its terms: Victoria v. The
Commonwealth [1975] HCA 39; (1975) 134 CLR 81, at pp 118, 162, 179,
180."
