"It is true that some files are missing. We are trying to get the copies of those files ready," Jaiswal said in the Upper House.
"We are trying to find all documents that were not found in the coal ministry," he said.
"We would have lodged an FIR if the files were stolen, but they are missing," he said when Leader of Opposition in the Rajya Sabha Arun Jaitley interrupted him and asked why a complaint was not lodged.
"I wonder as to who would want to make files prior to 2004 disappear?" said the Coal Minister.
He said he is ready to face action if found guilty.
"I am ready to face punishment if any of the allegations made against me are proven true," said Jaiswal.
An uproar started in the House immediately after Jaiswal made his statement.
The Rajya Sabha was adjourned till 2 pm.
