Pakistan Tehreek-e-Insaf (PTI) Chairman and former prime minister Imran Khan on Saturday challenged the amendments made to the Official Secrets Act and Pakistan Army Act in the Supreme Court (SC).

The amendments to the Pakistan Army Act of 1952 and the Official Secrets Act of 1923 were made last month after being approved by the lower and upper chambers of parliament, as well as apparently the President's Office.

One of the changes made to the Official Secrets Act is that a person can now be charged with a crime if they "knowingly or intentionally obstructs, impedes, or defeats any measure taken by the government for the maintenance of public order or for the prevention of any actual or imminent threat to the security of Pakistan."

Another change made to the Official Secrets Act is that those accused of violating the law will be tried in a special court, and a judgment will be made within 30 days of the completion of the hearing.

The amendments to the Pakistan Army Act also make it a crime for military personnel or officers performing duties of a "sensitive nature" to engage in any "political activity" for up to two years following "retirement, resignation, or dismissal," and for five years following "termination of service."

The petition was filed by Advocate Shoaib Shaheen under Article 184 of the Constitution.

The petition argues that the amendments violate people's fundamental rights.

It also states that President Arif Alvi, who is a PTI member, has said on social media that he does not approve of the passage of these amendments.
