The court order came after a petition filed against govt ads detailing government stance on offshore wealth in an attempt to fend off public criticism.
Petitioner Javed Badar pleaded that advertisements worth millions of rupees were being given in newspapers and channels from the public exchequer.
The clarifications are glorified on behalf of Sharif brothers in those ads, claimed the petitioner.
He said it was illegal to run face-saving campaign from public taxes. He urged the court to direct prime minister to deposit all expenses of advertisements in the national exchequer.
The government, while hearing the plea, asked the federal lawyer to turn up with an official reply in this regard.
Prime Minister Nawaz Sharif had pledged to resign if a probe related to the Panama Papers tax scandal found his family had committed any wrongdoing.
Three of Sharif’s children were named in a vast leak of documents from Panama-based law firm Mossack Fonseca this month that has revealed how the wealthy hide their money.
He also pledged to create a new judicial commission headed by a retired judge to investigate the allegations, after his first proposal was rejected by lawmakers.
