The government had, on October 11, ordered a vigilance probe against Chandy in connection with the multi-crore-rupee scam.
The decision was taken on the basis of the findings of the Justice G Sivarajan Commission, which had probed the scam.
The commission was appointed by the previous Chandy government after allegations surfaced about Saritha S Nair and Biju Radhakrishnan duping several people of crores of rupees by offering solar panel solutions to them.
He also mentioned that the government's decision not to give him a copy of the report was "unilateral" and "illogical" and sought to know about the legal opinion it received on the report of the commission.

Earlier in the day, Chandy told PTI that he was still in the dark about the findings of the commission.
The Congress leader also said even though the government had come out with accusations, nobody had seen the report of the commission.
He added that if he wanted to challenge the facts and findings of the commission in court, he should first be aware of the contents of its report.
Asked whether he planned to file a defamation case against Saritha S Nair, who levelled the charges against him, Chandy said, "Only after getting to know about the facts and findings, can further steps be taken in this regard."
Asked whether theCPI(M)-led LDF government's move against him was political, Chandy said all the present accusations were levelled by the current dispensation.
Besides Chandy, the Kerala government had also ordered a probe against former ministers Aryadan Mohamed and Thiruvanchoor Radhakrishnan, after lodging a case against them.
Two former Congress MLAs -- Thampanoor Ravi and Benny Benhanan -- have also been brought under the ambit of the investigation.
The charge against Radhakrishnan, who was the home and vigilance minister in the Chandy cabinet, was that he had tried to protect the former chief minister and "illegally" used police officers under him to "influence" the case.
According to the commission, a vigilance case should be registered against former power minister Mohammed, as he had allegedly helped Saritha's company, 'Team Solar', illegally.
Certain ministers in the Chandy cabinet, besides some Congress MPs and MLAs, were named by Saritha in connection with the solar scam, in the letter she wrote when she was in jail.
