20 If the two applications were to be heard separately, it makes no sense for the issue of remuneration of RTA's salaried staff to continue to be the subject of the PSA proceedings; it would be unnecessarily duplicative and the Full Bench would not countenance it. However, the removal of the RTA from consideration in the PSA's application would be an unjustifiable imposition on the PSA given that in the preparation of its case, it has proceeded on a basis, agreed with the RTA, that employees in the RTA are representative of the employees covered by the PSA's proposed award. Further, an important objective of the PSA's application is to maintain a common salary outcome across the public sector, including the RTA. A common salary outcome has been the norm since 1993. Regardless of the merits of this objective, if there were to be separate proceedings the objective would be rendered nugatory in the absence of proper debate on the issue.
21 The RTA submitted it had no option but to respond to the PSA's application until such time as "it could endeavour to extricate itself from the public sector wide case". It was submitted that if it had not participated, it would have risked an adverse decision being made against it by default. Mr Nolan of counsel for the RTA contended that participation could not be characterised as acceptance of, or even acquiescence in, a particular course of action.
22 We accept that the RTA had no option but to respond to the PSA's application. However, responding to the application did not require the RTA to consent to being used as part of an agreed sample, or to the directions made by the Commission. Given that in April there was an intention to file, or expectation of filing, a separate application, the onus was on the RTA to disclose that. In the result, in April the RTA, through its legal representatives, expressly agreed to the conduct of the PSA proceedings on a particular basis that included the RTA as part of the case. This set the PSA proceedings on a particular course, which to now abandon would be unfairly prejudicial to the PSA.
23 It was submitted for the DPE that the material filed by the PSA in support of its application, which included material relating to the RTA, would not be rendered otiose if the RTA's application was separately progressed because "that very material will be central to the consideration and determination of the RTA award." However, the PSA has obviously constructed its whole case on the basis that the RTA material forms an integral part of its claim. If that material can be addressed in the context of the PSA's application without prejudicing the outcome for the RTA, the most convenient way forward is to take that course, rather than to transplant it into separate proceedings. Furthermore, a detriment may potentially arise for the PSA if it was unable to prosecute a case that the RTA was representative of changes in conditions elsewhere within the public sector, such that it and other agencies should be required to increase the salaries of their employees. That is to say, the RTA's case for a new award may be fully heard in the joined proceedings, but the PSA's case (as it has been advanced in Matter No IRC 445 of 2008) may not be, if the RTA's separate application is allowed to proceed as such.
