What is the purpose of passing resolutions by the Houses of Legislatures for this matter?
The purpose of passing resolutions by the Houses of Legislatures for this matter is to indicate that it is desirable for certain matters, which Parliament has no power to legislate on except through articles 249 and 250, to be regulated in those States by a law passed by Parliament. This process allows for the possibility of legislation covering multiple states if they all agree on the matter, as well as other states potentially adopting such legislation later on.
