The presidential poll will take place next month and Uhuru Kenyatta is seeking re-election.
On Friday, after a case brought by the opposition, the High Court ordered the electoral commission not to print ballot papers.
Mr Kenyatta insisted the election would go ahead as planned.
"This kind of intimidation will not be allowed and the election date will not change," he said.
He said the judiciary could not claim independence and then use it to interfere with the functioning of the executive and other arms of government.
The High Court argued that the tendering process for the ballot papers had not been transparent enough.
The opposition National Super Alliance (Nasa) alleged that the president had links to Al Ghurair, the Dubai-based firm that won the $24m (Â£18m) tender.
Al Ghurair and Mr Kenyatta deny any wrongdoing.
The judges ruled that the company could still print ballots for the parliamentary and county elections, but the tender for presidential ballots should be re-advertised.
Local media have reported that whoever takes on the job of printing and distributing the ballot papers will have just 30 days to do what is usually a 45-day task.
In a separate development, Raila Odinga, Mr Kenyatta's main contender, was taken ill and admitted to hospital on Sunday with what his campaign team said was suspected food poisoning.
Mr Odinga, speaking shortly after he was discharged from the hospital in the coastal city of Mombasa, said that he was "fit as a fiddle".
"I had stomach pains, which have since disappeared after getting treatment," Mr Odinga said, adding: "I have been discharged to go to Nairobi to continue with my campaigns."
Meanwhile, several people have reportedly been killed in clashes between rival political groups, rekindling memories of post-election violence in 2007-2008 that left more than 1,000 people dead.

Demonstrators marched outside the Iranian embassy accusing Tehran of interfering in Afghanistan's affairs.
Soaring fuel prices have angered many Afghans at a time of high demand during winter.
Afghan officials say 2,500 fuel tankers are stranded at the border. Iran denies blocking fuel exports to Afghanistan.
It is thought the Iranian government fears the fuel could be used by foreign forces, but Afghan officials say these concerns are unfounded.
Earlier this week Iran's ambassador in Kabul, Fadahoseyn Malaki, dismissed reports that Iran had barred fuel exports to Afghanistan.
"We give fuel to the Afghan nation," he told a news conference, although he added his government still had concerns which "should be addressed".
Friday's demonstration was led by Afghan MP Najib Kabuli, who has organised similar protests against Iran in the past.

The A344 next to the monument was shut in June to "restore the dignity" of the stone circle as part of a Â£27m project.
Residents of villages including Shrewton and Orcheston say their lanes have become "rat runs" for drivers avoiding congestion on the A303.
Campaigners will collect signatures for a petition this weekend.
Janice Hassett, from the Shrewton Traffic Action Group (Stag), said: "The A344 should not have been closed before the A303 was dualled.
"The A303 at Stonehenge Bottom was bad before, but it's a nightmare now.
"Traffic is stupidly backing up to Thruxton on a holiday weekend.
"Sat-navs are sending people right through our villages. There's going to be an accident."
The petition is asking for "urgent action" to be taken to tackle high volumes of non-local traffic using the B3086 through Shrewton, a 20mph speed limit to be introduced and better signage to be installed.
