Justice George Odunga has overturned a decision by KNEC to cancel the results of Chebuyusi High School.
The judge said that the cancellation of the results was not done in accordance with the law.
He has also given KNEC 14 days to carry out investigations into the allegations of cheating against the school and make a determination on whether they will cancel or uphold the results.
In his ruling he further noted that KNEC has powers to cancel results but only when done according to the law.
The court has, however, given the examination body 14 days to investigate allegations of cheating and determine on whether they will cancel or uphold the results.
Results of all the 190 students were cancelled among the 1,025 others countrywide over alleged cheating.
Knec cited collusion in the Chemistry and Biology papers.
The parents went to court to suspend the decision by Knec and the Ministry of Education.
Through the period of 2017 KCSE examinations and the month during which the exams were marked, neither the school nor the students or parents were informed of any report on irregularity.
