After the Speaker's ruling was made public, the major opposition party in the parliament, the Pakistan Muslim League, and the non-elected party, the Pakistan Tehreek-e-Insaaf (PTI), filed two separate petition in the supreme court, challenging the National Assembly Speaker Dr. Fehmida Mirza's ruling to save Prime Minister Yousuf Raza Gilani from disqualification.
The petitioners pointed out that Article 184(3) of the Constitution stands to "disqualified in light of the apex court's verdict and that he should be barred from performing further duties as the prime minister."

On 6 June 2012, the Supreme Court admitted the petitions and a three-member bench was formed to be headed by Chief Justice Iftikhar Mohammad Chaudhry to hear the petitions.
After hearing petitions by both sides, the notices were sent to prime minister, speaker of the national assembly, and other concerned offices to the case.
The hearing of the petitions was subsequently adjourned to 14 June 2012.
On 15 June, Gillani's lawyer senator Aitzaz Ahsan defended speaker's move, and argued that "the office of speaker was no more 'a post office' after the 18th Amendment as it had been drastically changed" and that "[the speaker] had used her quasi judicial powers and gave her ruling over the issue with due application of her mind".
Ahsan maintained that the prime minister had accepted the conviction but not disqualification.
On 17 June, Ahsan concluded that speaker's ruling was in accordance with parliamentary ethics and reiterated that the ruling in the contempt of court case did not refer to a disqualification of the prime minister.
Mirza also submitted the written statement in which, she maintained that the court's ruling did not order that a reference on the issue should directly be sent to the Election Commission, and has had the constitutional authority to decide over the disqualification of a member of the assembly.
Her written statement was discarded by the supreme court, and reserved the final decision of Gillani's qualification matter.
At the end of the proceedings, the chief justice marked that the petitions had stated that a "convicted person" was representing the people; the prime minister represented the public and not a party.
Minutes before adjourning the court, the chief justice quoted: "The fate of the people was in the hands of a man who had been convicted by the Supreme Court... (...)..".

Finally on 19 June 2012, the Supreme Court of Pakistan ousted and further disqualified Prime Minister Gillani citing the earlier conviction on 26 April 2012.
The Supreme Court in its standing orders, said that "Gillani was ineligible to hold the Prime Minister's office after April 26th conviction" and all orders given by him till date would stand null and void.
Consequently, the Election Commission issued the government notification with regards to the disqualification of Gillani.
The country's election commission noted that, accepting the rulings of Supreme Court, Gillani was disqualified as a member of parliament with effect immediately from 26 April 2012.
