ISLAMABAD: Pakistan's top court said on Saturday all political activities in the country must be carried out within the legal and constitutional confines after a group of angry workers belonging to the ruling Pakistan Tehreek-e-Insaf (PTI) party stormed the Sindh House building in the federal capital on Friday.

A two-member bench of the apex court, headed by Chief Justice Umar Ata Bandial, took up the issue while involving the leading political parties in the matter after the Supreme Court Bar Association asked it to prevent the government from keeping its lawmakers from participating in the no-confidence vote against Prime Minister Imran Khan.

Angry PTI supporters entered Sindh House which was sheltering the dissenting lawmakers belonging to the ruling party. Sindh House is an official building in Islamabad dedicated to the government of southern Sindh province, which is ruled by the opposition Pakistan Peoples Party (PPP).

Prior to that, the prime minister had described the place as the "hub of horse trading," implying that the opposition was using money to buy the loyalties of his party members ahead of the crucial vote that can topple his government.

The apex court did not show any interest in dealing with issues related to Article 95 that deals with the no-trust vote, though it expressed concern over the attack on Sindh House.

"With respect to the proceedings under Article 95 being conducted in accordance with the Constitution and the law, except the incident of the Friday last — when a group of charged PTI activists breached the Sindh House twice — presently there is nothing before us that invites our attention either in the public interest or on account of the violation of the constitutional principles," Dawn newspaper quoted the chief justice as saying.

The court also clarified it was not taking a suo moto notice on the issue, adding that the bench was hearing the Supreme Court Bar Association's petition.

The Supreme Court involved PTI, Pakistan Muslim League-Nawaz, Pakistan Peoples Party, Jamiat-e-Ulama-e-Islam-Fazl, Balochistan National Party-Mengal and Awami National Party to further explore the issue.

The attorney general informed the bench that the government wanted to file a reference under Article 186 of the Constitution to seek an interpretation of Article 63-A, which deals with disqualification of parliamentarians. However, the chief justice said the top court would deal with the reference only when it was filed.

He also reiterated that the storming of Sindh House was "beyond the right of freedom of expression and lawful protest."

The court will now take up the matter on Monday and look into the government's reference on Article 63-A, if filed.
