The learned trial judge also found that the action of those members of the federation who were engaged to work with the Hurseys, in leaving the job to bring about their dismissal, was unlawful, but with respect I am not disposed to agree with this conclusion. Section 36 (1) (e) of the Stevedoring Industry Act does authorize the Stevedoring Industry Authority to cancel or suspend the registration of a waterside worker who has failed to complete an engagement for employment as a waterside worker, and the power so conferred was employed in relation to waterside workers who walked off the job to bring about the dismissal of the Hurseys. This provision does not, however, make the walking off unlawful, as Burbury C.J. appears to say. His Honour, furthermore, treated the walking off as inducing a breach of contract on the part of the employers who dismissed the Hurseys but those dismissals were not, so far as I can see, a breach of contract by the employers. Had the walking off been "without reasonable cause or excuse", it would have been a breach of s. 44 (2) of the Stevedoring Industry Act, which is as follows: "A registered waterside worker shall not, without reasonable cause or excuse, refuse to accept employment or perform work in stevedoring operations with another person who is a registered waterside worker or is employed as a waterside worker by virtue of section forty of this Act". There was, however, no finding of absence of reasonable cause or excuse and I am not prepared now to make such a finding. It may be that after 17th June 1958 when Port Order 38 of 1948 was revoked, there was nothing that could be regarded as reasonable cause or excuse except that the Hurseys were not members of the federation; but in a case where the learned trial judge has considered all aspects of the case so carefully, I would have no confidence in making a finding in favour of the Hurseys that he has refrained from making, particularly as the Chief Justice proceeded on the finding that the Hurseys remained members of the federation, whereas I have reached the conclusion that they ceased to be members. I have therefore come to the conclusion that the finding that the walking off was unlawful cannot stand and it would follow that the carrying out of an agreement to walk off, if that were all, would not be an actionable conspiracy. I am not, however, prepared to regard the walking off as something done pursuant to an agreement separate from the general agreement to prevent the Hurseys from working. My view of the findings of the Chief Justice of Tasmania is that there was a combination to prevent the Hurseys from working and to do so by means some of which were unlawful, so that the combination was, as a whole, an unlawful conspiracy. This conspiracy was, to start with, carried out by action not in itself unlawful, namely, by the men walking off the job on 5th and 6th February. Later, and until the injunction was granted, it was carried out by unlawful means, namely, picketing. After the injunction, there was a reversion to the earlier tactics. In such a case, I do not think it possible to dissect what was done pursuant to the agreement into what could have been done lawfully and what could not. The agreement to use unlawful means vitiated it entirely and made it an actionable conspiracy when it was carried out so as to cause damage to the plaintiffs; indeed, it was from the start an indictable conspiracy. In other words, the conspiracy was actionable because some of the means for carrying it out were unlawful and, therefore, all that was done was done pursuant to an unlawful conspiracy. Therefore, my conclusion as to the walking off is that, although it was not unlawful in itself, it is not to be disregarded in determining whether the Hurseys suffered damage by reason of the carrying out of an actionable conspiracy or in assessing their damages.
