That was initiated probably back in the late nineties, when we were doing our consultations on renewing the commission. It was a proposal that was supported by, interestingly, both industry and labour, in the sense that we had come forward with reports on the progress with which industry has complied with our regulations, on the economic side, and our data was quite surprising. Only four claims out of almost 3,000 to date for which we have rendered decisions were actually deemed to be invalid. In other words, industry's track record, in terms of substantiating their claim for trade secrecy, has been excellent, while not so good on the health and safety side. But that's where we remain quite vigilant.
So in this case the suggestion to go to a declaration approach as opposed to requiring substantiation in every instance was put forward jointly by labour and industry. Labour was interested in it because, from their perspective, any sort of efficiency gains that can be gleaned on the economic side should be reinvested into the health and safety evaluation side of our operations, and that's a commitment we made.
