The observation was made by a five-judge constitution bench headed by Chief Justice Dipak Misra which is hearing two petitions to decide questions including whether the court can rely on or refer to parliamentary committee reports in judicial proceedings.
The issue whether a parliamentary panel report can be relied upon in judicial proceedings had arisen after the petitioners had referred to the 81st Report of Parliamentary Standing Committee, issued on December 22, 2014, allegedly indicting some pharma firms for conducting trials of the controversial Human Papilloma Virus (HPV) vaccine.
It said that the apex court can enforce its orders under Article 142 and ask for setting up of commissions, seek reports and order enquiry to ensure justice.
At the outset, Attorney General (AG) K K Venugopal referred to the privileges of the House and its committees and the concept of separation of powers and said that no report of any committee of Parliament can be subjected to "judicial scrutiny or review".

In a parliamentary form of democracy, there is a doctrine of collective responsibility of the government and "the question is where do we draw the line. Like separation of power, the power of judicial review is also part of basic structure," the bench observed.
"It is not that our power of judicial review gets affected. We can take up a case and do the needful on our own," it said, adding the issue was that can a PIL have an affidavit containing details of a report of a parliamentary committee.
"Article 21 is worded negatively but Your Lordships have read at least 30 positive rights into it. And they cannot be enforced," Venugopal said.
"It can be enforced. Take our orders for ensuring green environment. My learned brother judge, Justice Sikri's order ensured that we could breathe after Diwali," Justice Chandrachud said, adding that the order ensured compliance of right to clean environment as fundamental right.
The broad separation of powers, which is a part of the basic structure of the Constitution, would prevent the courts from subjecting the reports of Parliamentary Committees to judicial scrutiny or review, he said.
Earlier, some pharma companies had said the report of a parliamentary standing committee has "persuasive" value but it is neither binding, nor can it be used to prove disputed facts.
The case came up for hearing in the apex court in 2012 and centred around aspects relating to action taken by the Drugs Controller General of India and the Indian Council of Medical Research pertaining to the approval of HPV vaccine manufactured by M/s GlaxoSmithKline Asia Pvt Ltd and MSD Pharmaceuticals Pvt Ltd for preventing cervical cancer among women.
