The Electoral Commission of Pakistan (ECP) notified Qasim Suri on Wednesday as a member of the National Assembly.
The decision came after the electoral court of the Baluchistan High Court last week declared the election of Suri to the National Assembly void.
Suri was elected as MNA of NA-265 (Quetta-II) on a ticket from Pakistan Tehreek-i-Insaf (PTI) in the general elections held in July last year.
The result was questioned by Nawabzada Lashkari Raisani, who had filed a petition against an alleged fraud in the constituency.
On Friday, the electoral court also ordered a re-election in the constituency. Suri remains eligible to challenge the re-election for which the ECP has not yet announced a date.
On Tuesday, Suri filed a petition in the Supreme Court to challenge the verdict of the BHC electoral tribunal.
The petition argued that Suri could not be blamed for irregularities in the elections. The appeal further alleged that the court did not consider the facts of the matter and urged the superior court to declare its verdict void.
