Flipkart, the e-commerce platform controlled by Walmart (NYSE:WMT), is facing yet another antitrust investigation in India. The All India Online Vendors Association filed an appeal with the National Company Law Appellate Tribunal (NCLAT), asking the regulatory body to investigate Flipkart amid allegations of unfair business practices related to its dominant market position. The NCLAT has turned the matter over to the director general -- India's anti-competitive watchdog --saying that the regulator "is directed to initiate [a] probe against Flipkart." 

The Competition Commission of India (CCI) had investigated similar accusations in 2018 and found that neither Flipkart nor Amazon (NASDAQ:AMZN) had violated antitrust regulations. This latest decision by the NCLAT overturns that decision.

The complaint alleges that Flipkart favors certain small vendors that sell on its platform, "promoting" their products over others. It also accuses the company of selling products at a loss, ultimately driving its smaller e-commerce rivals out of business, while discriminating against other small vendors. 

The CCI ordered new investigations into both Flipkart and Amazon back in January, based on allegations by a trade group that the tech companies violated competition laws and ran afoul of regulations due to the pairs use of heavy discounts to attract customers. Amazon filed a legal challenge early last month asking courts in India to quash the probe, saying it would damage the company's reputation and cause it "irreparable" loss. 

An Indian court temporarily stayed the investigation while it determines whether the probe should have been launched at all.
