Barrister Javed Iqbal Jaffrey has filed a petition before the Supreme Court of Pakistan for employing "lie detecting machine" on Prime Minister Yousaf Raza Gillani and Law Minister Babar Awan to expose their alleged 'lie' about withdrawal of judges' restoration notification. Jaffrey said the factual position should be made public. So, both prime minister and law minister be made to pass through the lie detecting machine.
