The Australian ombudsman is in the traditional mould of ombudsmen around the world, in that he is a person who makes recommendations and suggests solutions. He has no power to make decisions or overturn decisions. The power is in the production of the report. And as I said earlier, in terms of the major recommendations in his public reports from 2005-06, agencies accepted 49 of the 51 suggestions.
It's a pretty brave agency that would not accept a recommendation of the ombudsman, unless there were pretty solid grounds not to do so. The only occasions I'm aware of when they don't accept the recommendations is when there may be legislative or legal reasons why things can't be done.
