Emergency powers just to solve traffic? How about poverty, will the incoming administration need emergency powers to address the needs of the poor? How about other things, more serious than traffic--will Duterte ask that he be given enormous latitude just to solve them?
The advantage that this administration sees if given these emergency powers is simply the right to do things without any question from any sector, period. For example, the Duterte administration proposes to build additional roads. Under an emergency situation, this proposal does not have to go thru the tedious and often disruptive process of bidding for it before any construction undertaken.
If that is the only reason why Duterte's bright boys are suggesting emergency powers, putangina, they are not thinking straight.
