As regards to the press releases, the hospital submitted in its affidavit that ahead of the issuance of the first press note on September 23, 2016, J Jayalalithaa was involved in its preparation.
J Jayalalithaa had said information about her hospitalisation should be publicised so that there was "no panic."
Subsequently, the press notes detailing her condition were sent to the then chief secretary Rama Mohana Rao and health secretary J Radhakrishnan, who in turn approved them for release to the media.
On Friday, government secretary to former governor Ch Vidya Sagar Rao, Ramesh Chand Meena, and Apollo Hospital's Subbiah Viswanathan were among those who appeared before the commission, and counsel for Sasikala, Raja Senthoor Pandian, cross-examined them.
J Jayalalithaa had passed away on December 5, 2016, after being treated in the hospital for 75 days from September 22, 2016, for various ailments.
In September 2017, the state government had constituted a probe panel under the Commissions of Inquiry Act, mandating it to inquire into the circumstances leading to J Jayalalithaa's hospitalisation on September 22, 2016, and the treatment provided at the hospital till her demise.
The commission, whose term has been twice extended since then, had invited all those having "personal knowledge and direct acquaintance" to furnish information related to her.
Several people, including present Deputy Chief Minister O Panneerselvam and his followers, had earlier raised suspicions around the circumstances leadin
