In this important judgment Justice Zhou decided that both SI 205/2018 [changing the rate and incidence of the Intermediated Money Transfer Tax] and the policy decision it gave effect to [as stated in the Minister's Supplementary Budget Presentation on 1st August 2019] were inconsistent with the Constitution and therefore void of legal effect. He cited inconsistency with section of the Constitution 134(a) - which bars Parliament from delegating its primary law-making power - and the constitutional principle of Separation of Powers.
Both the policy decision and the SI were accordingly set aside.
