India aims to tighten rules around the scrutiny of mergers and acquisitions under proposed legislation that could particularly affect global tech firms that do a lot of business there.

The proposal is part of an overhaul of India’s competition law in a bill that was introduced in parliament on Friday and could be passed as soon as next week.

Under current law, the Competition Commission of India (CCI) reviews mergers and acquisitions that surpass thresholds for assets or turnover.

But many high-value deals between technology firms that have a big presence in India have escaped scrutiny because the companies involved have had few assets and low turnover there, Reuters reported from New Delhi.

Facebook’s acquisition of WhatsApp in 2014 for $19 billion, for example, required no CCI clearance, even as WhatsApp counted India as a major market, lawyers say.

The draft law proposes all deals worth over Rs. 20 billion ($250 million) should be subject to antitrust scrutiny if the companies have substantial business operations in India.

“The hotly debated deal value test seeks to attract scrutiny of transactions where parties do not meet the conventional asset and turnover thresholds particularly in the tech space,” said Anisha Chand, a partner specializing in antitrust law at Indian law firm Khaitan & Co.

“If passed in the present form, the incoming amendment may likely result in a jump in (the) number of transactions particularly in new age markets to require prior clearance,” she added.

The deal value threshold for scrutiny is in line with antitrust regulations in Germany and Austria, public policy consulting firm Koan Advisory said in a note on Friday.
