The judicial panel also issued notices to other government officials yesterday, including the state excise commissioner to file their affidavits, who are yet to do so despite issuance of notices earlier.
The bootlegger, Baidhar Bhoi of Bada Jharilo village was the first victim of the tragedy which claimed at least 40 lives in February this year.
Bhoi had consumed his own preparation made using tincture containing high alcoholic percentage.
When his condition deteriorated on the night of February 7, he was rushed to a private hospital in Bhubaneswar where doctors declared him brought dead.
His family members, sensing trouble ahead, cremated the body in the wee hours of February 8 in his native village before anyone could get a hint of the imminent tragedy waiting to happen.
Yesterday, when the Commission was informed that some of the family members of the deceased also want to put forth their grievances, Justice Naidu allowed it, asking them to file their affidavits before August 18, when the Commission would hold its next sitting.
Meanwhile, responding to the Commission's earlier notice, at least 20 medicine manufacturing units which use ethyl alcohol as one of the key components for some drugs, have also filed affidavits before it.
