In his nine-page affidavit which will be taken up by the apex court at its hearing on Wednesday, CBI Director Ranjit Sinha detailed at least four changes, two made by the Law Minister and two by joint secretaries of PMO and Coal ministry Shatrughna Singh and A K Bhalla respectively.
The CBI version contradicts reports of Kumar's account that he was not involved in drafting the changes.
However, the affidavit said, "It is difficult at this stage to attribute each change to a particular person with certainty. The changes which can be termed significant are elaborated."
Sinha attributed two significant changes in the draft report to the Law Minister and said those would be seen in paragraph 1.21 and 1.23 of the final status report pertaining to preliminary enquiries (PE).

"The other tentative findings about non-preparation of broadsheet or chart by the screening committee to the best of our recollection was deleted by the Law Minister," it said.
"From paragraph 1.21 of PE 2, the tentative finding about the non-existence of a system regarding allocation of specific weightage/points was deleted at the instance of the officials of the PMO and the Coal Ministry," the affidavit said.
The Director, however, asserted that neither the central theme of status reports got changed after meetings nor any deletion of any evidence against any suspect or accused took place.
