The highly anticipated decision was made by Judges Willy Mutunga, Kalpana Rawal, Mohamed Ibrahim, Jackton Ojwang, and Dr Smokin Wanjala.
This is a big win for teachers in the country as they seek to earn salaries equivalent to those paid to other civil servants.
Early this month, Kenya National Union of Teachers (KNUT) threatened to call a countrywide strike for teachers if TSC fails to effect the Labour Court decision.
TSC on the other hand argued that the body does not have the amount the court had ordered them to pay. They moved to the Court of Appeal to push for the reversal of the ruling.
Today’s ruling mean that TSC require Sh17 billion each year to effect basic salary, which translates to Sh73 billion for the four years and backdated to 2013
