The next question is whether the contract was forbidden by the
Town Planning and Development Act 1920. Sec. 23 of that Act
provides that it shall not be lawful for any person to offer for sale
or to sell or to convey, transfer or otherwise dispose of any existing
allotment or parcel of land except in accordance with the provisions
of that Act, and by sec. 44 a penalty is imposed on any person who
subdivides, resubdivides, disposes of or deals with any land in contra-
vention of the provisions of Part III., Division II., of the Act, which
includes sec. 23. The Acts Interpretation Act 1915 of South Australia
(No.'1215), by sec. 4, provides that in every Act whenever passed,
unless the contrary intention appears, the expression, "this Act"
includes regulations, rules and by-laws made under the Act wherein the
expression occurs. Reg. 17 of the Regulations made under the Town
Planning and Development Act 1920 provides that after the coming into
operation of the Act any owner who desires to offer for sale, sell,
convey, transfer or otherwise dispose of any existing allotment or
parcel of land shall cause a plan to be prepared which shall comply
with the provisions of secs. 28, 33 and 34 of the Act. The regulations
following prescribe the steps to be taken to obtain approval of such
plan, the final steps being the issue by the Government Town
Planner of a certificate of approval (reg. 44) and the deposit by the
owner of the certificate and copies of the plan under sec. 35 of the
Act (reg. 46). On 15th November 1925, when the contract sued on
in this action was made, the certificate of approval had not been
issued, and the provisions of sec. 35 of the Act were not complied
with until 25th February 1926. There can, I think, be no doubt
that, leaving aside any question of illegality, the contract was and
was intended to be a binding agreement for sale of the land the
performance of which was not to be completed until the provisions
