Section 14 of the Bill states:

The repeal of section 261 of the Act of 2000 shall not have effect for the purpose of any notice issued under that section at any time before such repeal.

What is it that someone is doing up until the point of repeal that he or she can continue to do? I am asking so that we can be clear on it. What happens post repeal? Is that dealt with in some other provision of the Act? Is a replacement mechanism provided?
