The court also restrained the party from taking any further disciplinary actions against the senator who is a member of Peoples Democratic Party (PDP)
Justice Valentine Ashi of the Federal Capital Territory High Court, Apo, gave the order in his ruling.
Kashamu was suspended by the Senator Ahmed Makarfi-led National Caretaker Committee of the party a few hours to the commencement of the December 9 national convention.
The National Caretaker Committee of the party led by Senator Ahmed Makarfi had announced Buruji’s suspension, which it said would last for one month.
No reason was given for the decision of the party.
But our correspondent gathered that the party took the decision following the ruling of the Federal High Court in Abuja, which had struck out a suit filed by Kashamu, to stop the party from taking any disciplinary action against him.
