Competition cases turn on evidence about markets: how they are defined, who holds power in them, and what a given practice does to rivals and consumers. VA Partners builds that evidence and carries it through the proceeding. We act in investigations and enforcement before the Trade Competition Commission of Thailand, in disputes before the courts, and on compliance questions before they become cases.

Our work covers abuse of dominance, unfair trade practices, cartels and information exchange, vertical restraints, and the conduct of digital platforms, including pricing and ranking algorithms. We define the relevant market, measure market power, test theories of harm against the data, and estimate exposure under the TCCT's fine and settlement rules. Where an infringement has caused loss, we quantify it for follow-on claims.

For businesses that want to stay out of proceedings, we review pricing, trading terms, supplier arrangements and distribution against the TCCT's guidelines, and build compliance programmes and training around the conduct that carries real risk in their market.

The practice brings together lawyers and economists who have advised the TCCT, served on its subcommittees, and teach competition law and economics at Chulalongkorn and Ramkhamhaeng universities.
