Hope Democratic Party has sought the order of the Presidential Election Tribunal to restrain President Muhammadu Buhari from being sworn in on May 29, 2019.
The party filed a motion to that effect on May 9, 2019.
In the same vein, it sought an order to restrain the Chief Justice of Nigeria from swearing-in, administering the oath of office and oath of allegiance to the president on May 29, 2019.
The reasons for the position of the party are contained in the motion.
The motion, it said, was pursuant to Section 1, Sub-section 2 of the 1999 constitution as amended and under the jurisdiction of the tribunal.
The party argued that there was a petition still pending which was challenging the victory of the president during the last election.
The petition, the party said, had been served on the president and pleadings had been exchanged.
According to Hope Democratic Party, the preparations for the inauguration was despite the legal action over his victory.
It argued that it would be against the law to swear in the president since the validity of his election into office was still being challenged.
Respondents in the case include Buhari, the All Progressives Congress, APC, and the Independent National Electoral Commission, INEC.
