This is a question in general also applies to all laws. In all civil laws whenever there is an amendment to an existing act there are 2 lines which are always there inevitable in the repeal and savings section. They are:-
a. The old act is hereby repealed.
b. anything done or any action taken under the principal Act as amended by the said Ordinance, shall be deemed to have been done or taken under the principal Act, as amended by this Act.
Now my question is what does section b means legally ? Can anyone explain it or point to a good article in the internet ?
