to say what his duties and obligations are. There may be clear
cases where the buildings fall within the definition, but there are
many which may or may not fall within it, depending on the intended
user by either the builder or the building owner. Alternatively, the
words " nor alter or adapt any existing building to be used or occupied
wholly or in part as flats" are in excess of the power, and to this
extent clause 1 is invalid. Sec. 198 (1) of the Local Government Act
1928 must be confined to buildings not in existence when the by-law
came into operation, and does not extend to alteration of existing
buildings. The acts of erecting and constructing buildings must be
the ones regulated. Construction refers to the type of material
used (Ingwersen v. Borough of Ringwood (1) ). [Counsel referred to
the Local Government Act 1928, sec. 197 (5) (b) and Thirteenth
Schedule, Part I., clauses 30 and 33.] Whether sec. 198 (1) extends
to alterations of existing buildings or not, sec. 198 (3) (6), (c) and (d)
are confined to buildings and dwellings erected after the coming
into operation of the by-law. In so far as clause 1 of by-law 90
depends on these sub-sections, the clause must fail as to alterations
to existing buildings. The sub-clauses a, 6, c, e, f and j are bad
because they are oppressive and unreasonable (Inqwersen v. Borough
of Ringwood (2); R. v. Broad (3) ; Dewar v. Shire of Braybrook (4) ).
As to the existing prescription of areas, this is in excess of power
and is invalid and also void for uncertainty (Shaw v. City of Essendon
(5); Stewart v. City of Essendon (6); Corless v. City of Richmond
(7); Wansbrough v. City of Camberwell (8) ). " Allotment" of
land is quite an uncertain quantity. How is it to be determined :
by ownership, fences, or plan of subdivision ? It is not a regulation
of the act of building to prohibit building in a particular area.
Country Roads Board v. Neale Ads Pty. Ltd. (9) was decided upon a
power to prohibit. If any portion of clause 1 is invalid, then the
whole by-law must go (Olsen v. City of Camberwell (10) ). Is the
by-law with the invalid portion omitted so substantially different,
as to the subject matter dealt with, that the by-law making authority
would not have enacted it? The difficulty is in finding some test
for determining whether the authority would have enacted the valid
portion (In re By-Law No. XXIII. of the Corporation of the Town
of Glenelg ; Ex parte Madigan (11) ). The provisions in all the sub-
clauses in this by-law are so interwoven that, if you remove one,
