Hon ANDREW LITTLE: I'm not responsible for the decisions that the DHBs as employers take in their industrial relations environment except to say that it has been an issue for some months now that there is uncertainty and a lack of clarity about the commitments that both the DHBs and the Nurses Organisation have signed up to in relation to life-preserving services, which is a commitment that the Nurses Organisation gives to DHBs when industrial action takes place. In view of that uncertainty and that lack of clarity and the inability to reach agreement with the Nurses Organisation prior to the next round of industrial action, the DHBs have decided to get a ruling from the courts on exactly what meeting life-preserving standards means.
