A bench of justices Aftab Alam and Ranjana Prakash Desai agreed to consider the plea after counsel Prashant Bhushan raised suspicions on the credibility of the CBI probe, which he suspected was influenced by the Union home minister as IPS officers are under control of his ministry.
Bhushan told the court that the CBI probe giving a clean chit to AP police and stating that the encounter was genuine, "does not inspire confidence" as there were several loopholes in the report submitted by the agency.
He argued the post-mortem report and other findings of the CBI were done under apparent influence of the home minister, as the IPS officers are under the overall control of the home ministry.
Bhushan claimed that Azad, could not have been killed by AP police without the approval of the Home Minister, who was in touch with Azad in connection with ceasefire talks between Maoists and the government.
The court initially expressed its unwillingness to entertain the plea by Bhushan, who represented the slain journalist's wife, Bineeta Pandey.
The court, however, relented later and agreed to go through the written submissions given by him, assailing the CBI's findings.
The court, however, added, "We are making it clear that this court is not sitting over appeal of the CBI's investigation report."
The apex court also agreed to examine social activist Swami Agnivesh's plea to inspect the CBI's report which was, however, opposed by Additional Solicitor General Haren Raval, who appeared for the agency.
Azad and Pandey were killed in an alleged fake encounter in Adilabad district of Andhra Pradesh in July 2010.
