Mr Sakaja seeks to cite lack of public participation and availability of viable to alternatives to block Sonko’s ban.
Nairobi Senator Sakaja Johnson and 21 matatu saccos have taken on City Hall and Governor Mike over their decision to ban public service vehicles from the Central Business District (CBD).
In his case filed at the High Court on Monday morning, Mr Sakaja accuses Mr Sonko of failing to consult the public and stakeholders before effecting the ban.
City Hall, he argues, has also not provided millions of commuters viable alternatives to make their commute smooth and comfortable.
Police and traffic marshals started effecting the ban early Monday morning, forcing matatus to drop off passengers outside the CBD.
“I've gone to court because the actions of the county government are disadvantaging many Kenyans..... before you ban matatus provide an alternative. What happens to children? What happens to the elderly? You have not dealt with security, it is not lit. You have not even created walkways for people, so it is completely unfair and it must be lifted today,” said Mr Sakaja.
The matatu saccos claim that the ban has been effected without adequate notice and that it is being implemented in a haphazard manner.
They allege that the move has ignored public participation and several courts as well as tribunal orders that protects several operators from being hounded out of the city centre.
