National Assembly has fined Petroleum Cabinet Secretary John Munyes Sh500,000 for snubbing summons over the hike in fuel prices.
Munyes had been summoned by Committee on Finance to answer queries over the recent increase in fuel prices.
He wrote to the committee saying that he is in South Sudan on an official duty.
However, the committee chaired by Homa Bay Woman Representative Gladys Wanga said their report will also show that Munyes has been uncooperative.
The committee was last week granted an additional seven days to dig into fuel costing criteria.
Munyes who is known of snubbing Senate summons, in March defended the hike in fuel prices saying that EPRA uses a formula outlined in the Energy (Petroleum Pricing) Regulations of 2010 to calculate the applicable petroleum pump prices.
He said that the computation takes into account the landed costs, supplier margins, government taxes plus storage and distribution costs.
Meanwhile, the National Assembly committee on Delegated Legislation declared the Sh5.40 levy on a litre of diesel illegal after it established that the ministry ommitted diesel in a legal notice of increased levy but the government has been collecting the Sh5.40 on both diesel and petrol.
“The committee recommend to the House to annul the amendment order in entirety for contravening Section 11(1) and 4 of the Statutory Instruments Act, 2013, being out of the statutory timelines set out in Section 11 and lack of demonstration of public participation,” the committee says in a report.
The regulations were meant to fix a legal breach that omitted diesel from a law that allowed the State in July last year to collect the Sh5.40 Petroleum Development Levy.
EPRA revised upwards the price of super petrol, diesel and kerosene by Sh7.58, Sh7.94 and Sh12.97 per litre respectively.
Epra said the jump in prices was due to the lifting of the stabilisation fund which had cushioned consumers from previous increases.
