The learned judge constituting the Workers' Compensation Commission found that the interruption of the journey occasioned (AUSTRALIA)
by the call at the hotel was a substantial interruption in fact but was not an interruption by reason whereof in the circumstances of the particular case, the nature, extent, degree and content of the risk were materially changed or increased. The result of this con- clusion was to bring into operation the second of the two paragraphs of which S. 7 (1) (b) is composed, namely, the paragraph providing that an interruption or deviation shall not be deemed substantial if the nature, extent, degree and content of the risk were not thereby materially changed or increased. It accordingly made it necessary to treat the interruption as not a substantial interruption of or deviation from the journey within the meaning of the first of what it is convenient to refer to as the conditions of which the first paragraph of S. 7 (1) (b) is composed. Inasmuch as the interrup- tion was not one to which the first condition of S. 7 (1) (b) applied, it was contended by the employer, with at least a prima-facie appearance of logic, that it must come within the words " any other break in any such journey" which occur in the second condition of S. 7 (1) (b).
The argument for the employer was simple enough. The injury was received during or after a break in the journey. The break ex hypothesi was not a substantial interruption within the first condition it must, therefore, be an " other break" within the second condition. All that remained was for the Commission to decide whether, having regard to all the circumstances, it was to be deemed not to have been reasonably incidental to the journey. The Commission made a finding on this question. It found that in truth the interruption was not reasonably incidental to any such journey. On that finding the employer maintained that his case was complete, that the interruption constituted a break, that it was not reasonably incidental, and since it was not a substantial interruption or deviation within the first, it fell within the second of the two conditions in S. 7 (1) (b) negativing a claimant's title to compensation. In substance this is the view which Street C.J. adopted.
The second paragraph of S. 7 (1) (b), namely, that beginning
' An interruption of or deviation from any journey shall not be deemed," &., was added by Act No. 20 of 1951, S. 2 (b) (iv). Before it was SO added there were only two grounds upon which an interruption or deviation that had taken place in fact could be
