CBI's charge sheet claimed that Jindal had "conspired" with Koda and promised to help him in completing his term as the chief minister in return for allocation of the coal block in Jharkhand.
Koda, who was an Independent MLA, was chief minister of Jharkhand from September 14, 2006 to August 23, 2008 with the support of Congress, RJD and others.
"Naveen Jindal conspired with Madhu Koda and promised him to garner support of the Congress Party for his unstable government and help him in continuing as Chief Minister, Jharkhand," the charge sheet said.
Special CBI Judge Bharat Parashar after taking cognizance of the charge sheet today summoned as accused Jindal, Koda, former Minister of State for Coal Dasari Narayan Rao and 12 others, including give firms.
