Tata Sons cited legal opinions from former Chief Justice UU Lalit and former Supreme Court judge BN Srikrishna defending N Chandrasekaran's reappointment as Tata Group Chairman.
Tata Trusts questioned the validity of the September 17 board resolution, arguing that Article 121 requires a majority of its two nominees and that a casting vote cannot override this requirement.
Legal experts concurred that statutory fiduciary duties override contractual ones and that the presiding chairman validly exercised a casting vote following an equality of votes among board members.
