The bill is drafted so that subclause 21(1) is the linchpin; that is, there are numerous provisions that refer to the amount in 21(1).
Subclause 21(2) allows you to increase the amount by regulation. So in further references to subclause 21(1), which you see in subclauses 23(1), 24(3), 26(1), every time the reference is to subclause 24(1), it means $650 million, or such greater amount as is prescribed by regulation. I should clarify: the power to regulate is actually a power to increase the amount in the act. If you make the regulation the $650 million figure, you'll see in the electronic version of the bill that it actually increases.
Since there are references throughout the bill, and in calculations of reinsurance and so forth--for instance, if you go to the tribunal section, subclause 62(1), it is the linchpin there--it would require considerable redrafting if we simply remove subclause 21(1).
