The government suffered a major blow on Wednesday after a court ruled that Treasury CS Henry Rotich did not follow the right procedure when he presented the Finance Bill, 2018.
Justice Wilfrida Okwany has further said that there was no public participation on the bill before it was implemented.
"The finance bill including taxation cannot be implemented before going through Parliament " the judge held.
Okwany also said the Provisional Collection of Taxes and Duties 2018 is unconstitutional.
Activist Okiya Omtatah has sued the state in the case.
