Under the Competition Act, 2002, as amended by the Competition (Amendment) Act, 2023, a person acquiring control of another enterprise must give notice of the proposed combination to the Competition Commission of India within:

Section 6 of the Competition Act, 2002, prohibits a person or enterprise from giving effect to a combination unless notice of it has been given to the Competition Commission of India. Prior to the Competition (Amendment) Act, 2023, the notice had to be given within two hundred and ten days of the execution of the document of acquisition; the 2023 Amendment shortened the window to thirty days. The amendment also introduced the deal-value threshold, under which a filing is triggered where the transaction value exceeds two thousand crore rupees combined with a substantial business nexus with India. The standstill obligation continues to apply, so the combination cannot be given effect until approved or the prescribed period expires. Fifteen days, ninety days, one year or seven days are not the current window.
