Wajir Governor Mohammed Abdi's win in the August election has been nullified by the High Court.
Delivering the ruling, Justice Alfred Mabeya noted that the Governor's election was invalid after a petition by his predecessor Ahmed Abdullahi.
The court ruled that Abdi was not properly cleared to run for office since he did not have a valid undergraduate degree.
Judge Mabeya also cited that there were irregularities in the election.
The court has, therefore, ordered for a fresh election in 90 days.
Mr Abdi, who was elected on a Jubilee ticket, becomes the first Governor to lose his seat.
However, reports indicate that his lawyers are currently requesting a stay order pending appeal.
Petitioners challenged his win on grounds that he was not qualified for the seat.
Former County Boss, Mr Abdullahi accused Abdi of allegedly falsifying the documents he had presented to the Ethics and Anti Corruption Commission (EACC).
