I would agree. I've read some of the transcripts and discussion about sunset clauses and I don't agree at all; there are very good reasons for not having them.
A quick example is the restrictive covenant proposals. They were specifically introduced as technical amendments to counteract a decision of the Federal Court of Appeal called Manrell, wherein ultimately restrictive covenant receipts were found not to be taxable—a decision that was very surprising to a person like me. There are very good tax policy reasons for introducing such legislation.
This draft legislation goes back to 2004. If we had a sunset clause, you would have a whole bunch of people continuing to plan to make restrictive covenant proposals tax free, which in my view is ridiculous and ultimately introduces complications that would be further unintended.
So I don't agree with that idea whatsoever.
