The minister has noted a few such examples, such as when we don't have access to the expertise, the skill sets in question, or it's not the type of skill set that we would need on our payroll on a permanent basis. It could be that we need it on a very time-limited basis for a defined period of time. It could be in relation to an initiative that only has temporary funding; it would then not be appropriate to hire a full-time public servant if we had a six-month or twelve-month project to undertake. In this circumstance, we look for independent advice from outside the public service to help give critical perspectives on a project.
Those are some circumstances.
