A six-member Joint Investigation Team (JIT) set up by the Supreme Court to investigate charges of money laundering against 67-year-old Sharif and his family had submitted the report on July 10 to the court, which could cost him his job.
"The entire investigation was a farce and an eyewash and was undertaken with a predisposed mind to malign and implicate the respondents in some wrongdoing or the other," according to the objection filed by the Sharif family.
"The JIT report is not only against the law but also the constitution of the country and its finding are, therefore, of not legal value," he said.
But the JIT report is turning into a major challenge to Sharif. Opposition parties accuse his family of using their political influence to amass wealth by unlawful means and are demanding his resignation.
