First, it is necessary to consider the law. The Conciliation and
Arbitration Act, which has for its aim the preservation of industrial
peace, for the manifest purpose of securing to the people of Australia
the uninterrupted supply of their needs, declares that one of its
chief objects is "to facilitate and encourage the organization of
representative bodies of employers and of employees and the
submission of industrial disputes to the Court by organizations."
With that object, it empowers the creation of organizations and
practically invites men to join them in order that, if dissatisfied with
their working conditions, their dissatisfaction shall be dealt with
by a public tribunal, and shall not lead either to their dismissal
or their refusal to work, or the stoppage of public services either by
strikes or lock-outs. As one of the means of effectuating this end,
Parliament has enacted in sec. 9, so far as material here, that "an
employer shall not dismiss an employee . . . by reason of the
circumstance that the employee isa. . . member of an organiza-
tion." It has guarded the employer against any improper harassing,
by forbidding any prosecution except by leave of the President or
the Registrar. It also forbids employees from ceasing work by reason
of corresponding circumstances, and guards them similarly from
harassing prosecutions. And then it has enacted that, when all
outward circumstances are proved, the onus is on the defendant -
whether employer or employee - '* to prove that he was not actuated
by the reason alleged in the charge." In this case the defendant had,
therefore, to prove it was not actuated by the reason that Batchelor
was a member of the organization.
