Tata Trusts said it received relief in a regulatory probe, potentially allowing the controlling shareholder of Tata Group’s holding company to resume business as usual as it seeks to pick a new chairman.

The Trusts received an order from the Maharashtra Charity Commissioner dated Sept 2, closing a complaint related to a 1989 share transfer, according to a statement on Thursday. That complaint had triggered restrictions that prevented one of the Trusts from convening internal meetings.

The relief comes as a boost at a time of heightened leadership uncertainty triggered by Natarajan Chandrasekaran’s unexpected decision to step down as chairman of Tata Sons Pvt. Sir Ratan Tata Trust, one of the 13 Tata charities, had been unable to nominate a member for the new chairman-selection process because of the curbs.

Tata Trusts owns 66 percent in Tata Sons — which oversees the listed companies of the sprawling group that owns Taj hotels to Tetley tea. The 32 companies under the group’s umbrella — of which 26 are publicly listed — generated a combined revenue of about $185 billion in the year ended March 31.

The Charity Commissioner’s probe relates to a petition filed by Vijay Singh, a trustee of Tata Trusts. He alleged that 833 Tata Sons shares were improperly transferred from the Navajbai Ratan Tata Trust to Naval H. Tata without fair consideration, valid documentation, or proper approvals. These shares were subsequently inherited by Naval’s sons — Ratan, Noel, and Jimmy Tata.

Tata Trusts said the allegations were “part of a willful, malicious and orchestrated campaign” to discredit the Tata Group’s philanthropic arm.

The dismissal of the complaint strengthens the position of Noel Tata, head of Tata Trusts, at a moment when the group is seeking to reassure shareholders, market regulators and policymakers about its stability. It also bolsters confidence that the conglomerate can continue delivering on initiatives central to Prime Minister Narendra Modi’s ambitions to turn India into a global technology and manufacturing powerhouse.

Tata Sons has until early next year to find a successor for Chandra, who would step down at the end of his term in February.
