Sharif's party leaders, meanwhile, said that the report did not prove any specific wrongdoing on the part of the prime minister. The prime minister, he added, will not resign.
The Election Commission of Pakistan (ECP) can not initiate contempt of court proceedings against an individual as that right lies only with the Supreme Court and the High Courts, said Pakistan Tehreek-i-Insaf chief Imran Khan.
The six-member Joint Investigation Team (JIT) was set up in May by the Supreme Court with the mandate to probe the Sharif family for allegedly failing to provide the trail of money used to buy properties in London in 1990s.
After receiving the report, the top court allowed the petitioners and respondents in the case to obtain copy of the report from the apex court's registrar office.
The case was first reported by British media in 1996 when it claimed that the flats were purchased through money laundered by the Sharif family.
Defense Minister Khawaja Asif, on the other hand, termed the report "inconclusive" and a "source-based report" which has no worth before a court of law.
Embattled Pakistani Prime Minister Nawaz Sharif, who is facing graft allegations, today attacked his detractors, saying they are "hiding behind Panama Papers accountability" to oust him.
The probe team consists of 6 officials from the National Accountability Bureau, Federal Investigation Agency (FIA), Securities and Exchange Commission of Pakistan (SECP), State Bank of Pakistan, Inter-Services Intelligence (ISI) and Military Intelligence (MI) headed by Director General FIA Wajid Zia. The assets in question are four apartments costing several million pounds in Park Lane, London, which according to Panama Papers were purchased through off shore companies Nielson and Nescol but hidden from tax authorities in Pakistan.
With the Supreme Court now taking up the case once more, Sharif's political career hangs in the balance.
During the course of the investigation, those who will be present before the JIT include Prime Minister Nawaz Sharif, Punjab Chief Minister Shahbaz Sharif, and Maryam Nawaz, daughter of the prime minister.
