Customs and a particular individual. The placing of goods on a
wharf is not a transaction between the Customs and the wharf-
owner. The appointment of a sufferance wharf under sec. 17 is
not such a transaction. Sec. 270 does not authorize the making
of regulations which are not for compliance with the Act or for the
protection of the revenue, The bond, if valid, would entitle the Cus-
toms to recover from the defendants in respect of the loss of goods lost
through the negligence of an officer of the Customs for which under
sec, 34 the Customs are liable. Regs. 3 and 3a of the Customs
Regulations 1913 are ultra vires, Sec. 43 gives an option to a person
required to give a security to give it in any one or more of three
ways. Regs, 3 and 3a are inconsistent with sec. 43, for they take
away that option and provide that the only security which can be
given shall be a bond. If sec. 43 does not give such an option it
gives a discretion to the Collector, which cannot be taken away by
regulations, The case of Marine Board of Hobart vy. The Common-
wealth (1) was decided on the basis that the Marine Board was in
the same position as any member of the public; but the defendants
are not in that position (see Melbourne Harbour Trust Act 1915, sees.
46, 47, 48). The definition in sec. + of the Customs Act of " the
Customs" as the Department of Trade and Customs does not make
the Customs a legal entity. Pars. 1, 2 and 4 of the statement of
claim make a claim based on contract. In that view the present
plaintiffs are not parties to the bond and cannot sue upon it. See.
48 is invalid as being an exercise of the judicial power of the Com-
monwealth by the Legislature, and also because it is a law in respect
of contracts and not in respect of Customs, The effect of the section
is that the putting in suit of the bond is proof of a breach of it,
but the question of whether there has been a breach is for the Court
to decide. The contract evidenced by a bond of this kind is that
the obligee will pay the damages occasioned by the breach (see
8 & 9 Will. IIL c¢. 11, sec. 8), and sec. 48 says that judgment is to be
given for the amount of the bond.
