Can states extend their executive powers beyond what is expressly provided in the Constitution or laws made by Parliament? If not, why not?
No, states cannot extend their executive powers beyond what is expressly provided in the Constitution or laws made by Parliament. This is stated in the context that "executive power referred to in sub-clause (a) shall not, save as expressly provided in this Constitution or in any law made by Parliament, extend in any State 2*** to matters with respect to which the Legislature of the State has also power to make laws." The limitation is set to avoid any overlap or conflict between state and federal powers.
