870 THE FEDERATIONS AND THE UNION [part IV
in the coasting trade even if the isolated transaction were
otherwise within the words of the section. The words
“taken on board’ and ‘ to be carried * imported a contract
of carriage made on behalf of the ship, and did not include
a promise made by a Passenger or any other person not
authorized to bind the owner to carry on board the ship
goods as to which the owner did not incur any responsibility.
The Court, although they considered that the matter could
be disposed of on that ground, decided, as the Commonwealth
had intervened by permission, to give a decision on the
general question of the validity of the Act. Two objections
were made to its validity. First, that provisions for com-
pensation to seamen could not under any circumstances. fall
under the trade and commerce power of s. 51 of the Constitu-
tion; second, that if they did the particular Act was invalid for
wnother reason. The first question the Court declined to
deal with on the ground that it was abstract, but the second
uestion they dealt with in detail. S. 4, subsection 1, pro-
vided that the Act applied in relation to the employment of
seamen (a) on any ship registered in the Commonwealth
when engaged in the coasting trade, and (b) on any ship
(whether British or foreign) engaged in the coasting trade
if the seamen had been shipped under articles of agreement
entered into in Australia.
It appeared, therefore, that the law applied to all trade
between different Australian ports, and not merely to trade
between ports of different states ; if there were any doubt
about this as regards subsection 1 it was made clear by the
terms of subsection 2, which expressly declares that a ship is
to be deemed to be engaged in the coasting trade if she takes
on board passengers or cargo at one port in a state to be
carried to and landed at another port in the same state.
Now it was not open to argument that the power to make
laws with respect to trade and commerce with other countries
and among the states given by the Constitution extended
to authorize the Parliament to legislate with respect to the
internal trade of a state. It followed that the provisions
of 8. 4 of the Act went beyond the powers of the Parliament
