KARACHI: While turning down a petition filed against the petroleum pricing mechanism, the Sindh High Court (SHC) on Monday observed that determination of prices, levying taxes and formation of economic policy primarily came within the exclusive domain of the executive and legislature. The SHC further noted that in exercise of its constitutional jurisdiction, the court could not ordinarily interfere in fiscal policy matters unless they were patently without lawful authority, discriminatory and violative of any specific constitutional or statutory provision. A two-judge constitutional bench of the SHC headed by Justice Adnan-ul-Karim Memon further said that the petitioner had failed to establish infringement of any enforceable fundamental right capable of judicial enforcement in the facts and circumstances of the case.
