I agree with Senator White's point that self-appraisal is important to a point, but we all become a little subjective and we need to broaden the structure. We should examine best practice in other countries. If one is making a decision in business, one examines best practice elsewhere, one does not try to reinvent the wheel. We should examine best practice elsewhere and source one or two people from overseas parliaments who have done this type of reform to good effect within their jurisdiction and from whom we could usefully learn.
