I would be sympathetic, in abstracto, to Senator Coghlan's amendment about retrospective payments. I wonder, apart from the legal advice, whether, even in a practical industrial relations sense, it would be practicable. What point in the past would one select? In some cases, companies may have dissolved or disbanded and, in such circumstances, would responsibility revert to the State? If one adopts different dates or different places, difficulties of equity would arise. Unless the Government can persuade me otherwise, I would have thought a start-up date is the best basis on which to operate.
