Interior Cabinet Secretary Fred Matiang'i says Kenya is pretending to have a credible judiciary yet it does not have one, reports the Sunday Nation.
Last week, Chief Justice David Maraga warned government institutions against defying court orders, insisting that the judiciary is independent.
"Judiciary is an independent arm of government. When we have court orders, all government officers or institutions must comply with them," he wrote.
Judiciary has been flexing muscles with the executive since nullifying President Uhuru Kenyatta's victory in September last year.
And in the explosive interview, Matiang'i claimed that a number of court rulings favour Raila Odinga's NASA.
"Time has come for Kenyans to have a robust debate on the kind of judiciary we have. We are pretending to have a credible one whereby it is not.
"The Attorney General has been in court to have People's Assemblies declared illegal but nothing yet to come out. Courts only favour NASA," he said.
Further, Matiang'i accused courts of reinstating at least 172 police officers who were disciplined for engaging in various crimes.
