factory satisfies the conditions of cleanliness and hygiene to which
that section refers, and the application shall be granted. But if
the application is in respect of a dairy produce factory for the
manufacture of any other form of dairy produce than butter or
cheese then that application must be considered, first by the Advisory
Committee, and secondly by the Minister in the light of the com-
mercial and economic interests of the dairying industry, and if
the application would be prejudicial to those interests the Minister
may, under s. 58 (i), refuse it. The Minister is not obliged to
grant a licence to any applicant; he has a complete discretion,
he may grant only one licence, or he may grant many. But each
licence shall specify within its terms the maximum amount which
that licensee may manufacture. If the Minister decides that there
shall be a number of licences and the maximum amount which
each of those licensees may manufacture is, in the aggregate,
2,500 tons, the effect of s. 22 is that no licensee can increase his
quota of manufacture nor can any further licence be granted. If the
whole 2,500 tons is given by way of different quotas among different
licensees, the quota of each licensee is frozen unless one of the
existing licensees does not seek to renew his licence or goes out of
manufacture. The quota of each licensee is frozen, notwithstanding
that a particular licensee may not manufacture the whole of his
quota or any part of it. What is significant in sub-s. (2) of s. 22c
is, where this permit is granted, it is provided that every such
permit shall contain such conditions as the Minister thinks neces-
sary to ensure that this table margarine so manufactured does not
go into inter-State trade. The group of sections 22a to 22p inclusive,
inserted in 1940, is not in any way concerned with the purity or
forms of manufacture of margarine ; it is solely concerned with
controlling the quantity which may be manufactured and the
quantity which may be sold in Australia. The operation of the
Act is concerned with the furtherance of the interests of the dairying
industry and seeks to achieve that result by restricting the manu-
facture, sale and distribution of margarine in Australia. If that
construction be correct, and even if the Act so construed operates
wholly upon intra-State aspects of trade and commerce, yet never-
theless because of the declared object of the Act, its provisions
contravene s. 92 of the Constitution. The purpose and intention
for which the defendant carries on its business is manufacture for
sale intra-State and inter-State. The manufacture of table mar-
garine or the carrying on of a business of manufacturing table
margarine for sale inter-State falls within the immunity of s. 92 of
the Constitution. This Act, in its operation, strikes at that business
