In their report in the HIndu, Ravi Sharma and Sara Hiddleston state that "the committee has requested three months to re-examine and resubmit the report." Their report also addresses the plagiarism angle:
According to Dr. Mashelkar, it was only after the committee had submitted its report that it came to their notice through newspaper articles that some plagiarism had occurred: "We have identified eight to ten lines that have been extracted verbatim from Basheer's paper. As a scientist I see this as not a good practice. In keeping with the highest and best ethical practices we want to withdraw the report."
However, a 'subgroup' is being blamed for it:
Dr. Mashelkar termed it "very unfortunate" and expressed the opinion that the "technical inaccuracy" could have happened when the report was being "drafted by a sub group."
Here's the ToI report by Manoj Mitta:
But he blamed "a drafting sub-group" for the lapses. "These were unfortunately not detected in time and, therefore, not corrected," Mashelkar claimed, in his letter written after consulting the other technical experts in the committee.
And finally, Pallavi Bagla reports in the Indian Express:
“I am broken-hearted at being let down so badly,” an emotional Mashelkar told The Indian Express. “This is the first time such a thing has happened.” He said that a new report will be submitted in three months that will follow the “best ethical practices.”
“Being a scientist, I am so fussy about attributions but in the rush of the last working day, a slip did happen and I deeply regret it,” he said. He said he offered his “unconditional apologies for the inconvenience that has been caused to the Government” and that he took “full responsibility for this unfortunate development.”
