In consequence the Court of Conciliation and Arbitration felt free to treat an application to vary the old award as an occasion for making a new award by way of supplement to the old. The purpose was to cover more senior officers. With respect to them it embraced in the one award the members of the Federation of Salaried Officers of Railways Commissioners and the members of any other registered industrial organisation as well as the members of the Association of Railway Professional Officers of Australia. The award was called the " Senior Officers New South Wales Railways Award ". It included the office to which Davis seeks promotion, viz. "Estate Agent, Legal Estates Branch", though the office he holds was governed by the older award. The new award was to commence on 1st July 1946 and continue during the currency of the award of 21st June 1943. The importance of the instrument for present purposes is that it introduced the provision displacing seniority as the governing factor in promotion. It gave finality to the commissioner's decision. "Promotion", the award said, " shall be governed by relative ability, suitability, record, experience and seniority : Provided that in considering an officer's ability, suitability, record and experience regard shall be had to the nature and quality of his service in the Armed Forces of H.M. the King. The reason for passing over any senior officer for promotion to a higher position shall be stated in a recommendation by the Head of the Branch to the Commissioner whose decision upon the matter shall be final." The award provided for a board of reference and subsequently a report was made by the board concerning, among other things, the right of appeal of officers passed over for promotion. As a result the judge varied the foregoing provision as from June 1947 by removing the last words "whose decision upon the matter shall be final" and adding instead the following paragraph: - "If an officer considers he has been improperly passed over for any position carrying less than £1,300 per annum he may appeal to the Railways Appeals Board or to the commissioner. If he appeals to the Appeals Board and a decision is given in his favour, it shall not become effective unless and until it is endorsed by the commissioner. In respect of any matter arising out of this clause the commissioner's decision shall be final." We are not informed which party pressed for the respective portions of the foregoing clauses. But we do know that, in a log of claims delivered on 1st June 1942 before any of these awards or variations was made, the association sought (i) a triennial classification of officers in grades or classes by a board of reference, (ii) promotion from class to class in order of seniority subject to the senior man being suitable for the higher position, and (iii) the determination of suitability by the board of reference. The demand was for a separate board of reference for each State on which the department and the association should be equally represented, and there were express claims that the board of reference should classify officers in grades and classes, hear and determine all appeals by officers regarding their classification and inquire into and report to the department their opinion on any recommendation for the promotion of an officer not next in order of seniority. It is probably safe to assume, therefore, that the primary case for the organisation, considered as a whole, was that promotion should be by seniority where possible and that an appeal to a tribunal on which there was a representation of salaried officers should be open if a senior was passed over for promotion. If that was the case of the organisation it would, of course, be satisfied by the provisions of the State Act.
