Well, I have a couple of points.
First of all, your assumption, Mr. Chairman, is very much the same as our own was; that is to say, there'd be a high behavioural response to the court case finding that a certain return was tax-free. A lot of people would seek to transform their returns into exactly that, and that was the reason for the proposed change.
Second, what I said a moment ago about the time limits is right. Generally it's three years for individuals and four years for large corporations, but CRA has the ability to seek a waiver from a taxpayer to keep the tax return open, and it is possible that they might seek to do that in certain cases.
However, I think the most important point in this case is that with the announcement of the change, we think the behavioural response to the court case probably would have stopped. When it was announced by the Minister of Finance in 2003 that these payments, these rejigged non-competition payments, were no longer going to be tax-free, we think that the mass of people would have stopped setting them up, because there would have been no point. If they had persisted, notwithstanding the fact that they'd be taxable again--and perhaps taxable at a higher rate than capital gains, in some cases--and if the thing had become statute-barred, your point would have been exactly right, but if they changed their behaviour back to the old form as a result of the announcement, we wouldn't have that issue.
Finally, your essential point about the need for Parliament ultimately to enact these so that they do have effect remains absolutely valid.
