You make a good point.
I know we discussed it a little bit the last time, but it bears repeating that, to be on the safe side, section 18.7 was included because it does somewhat confirm the validity of this approach. That being said, the issue should perhaps be debated.
Some argue that it does not cause any problems; while others, on the contrary, believe it should be provided for in the enabling legislation. Either way, it's done. So we make a correction and cover everything by way of section 18.7, which reads as follows:
The validity of an incorporation by reference that conforms with section 18.1 and that was made before the day on which that section comes into force is confirmed.
So it covers previous cases.
