Continuing to evaluate legal options against Mistry:Tata

The promoter of the major operating Tata companies also refuted Mistry's allegations of wrongdoing in the affairs of Air Asia India by R Venkataramanan, a trustee of Tata Trusts.

Responding to Mistry's allegations of the company attempting to "muzzle and interfere with legal proceedings", Tata Sons said it has "never resorted" to such tactics.

"It is ironical that Mr Cyrus P Mistry continues to make statements that his actions are in the interest of the Tata group. On the contrary, his actions thus far have consistently harmed the reputation of the Tata group. Tata Sons continues to evaluate its legal options in this regard," Tata Sons said in a statement.

Tata Sons said it strongly rejected statement from Mistry "which seeks to insinuate wrongdoing" in the affairs of Air Asia India by Venkataramanan.

Tata Sons said: "On the contrary, Air Asia India with the support of Tata Sons has taken definitive steps both in civil and criminal courts which have cleared the air in relation to the mischievous allegations made by SP Group companies in the NCLT proceedings."

When contacted, Mistry's office did not offer comments. On Tuesday, the Esplanade Metropolitan Magistrate's Court in Mumbai took cognisance of a Rs 500-crore defamation complaint filed by Venkatramanan against Mistry and others, and directed them to appear before it on August 24.
