InBev is appealing a court ruling blocking its purchase of a large stake in SUN Interbrew. The brewing giant had agreed to buy SUN Trade's share in their Russian joint venture, SUN Interbrew, for €530m (US$705.2m) in August.

An individual filed a complaint, however, against a decision by the anti-trust regulator to approve the deal, saying its analysis of the impact of the deal on competition in Russia was faulty. The court later supported the complaint.

InBev said yesterday (1 December) that it is appealing this decision.

"InBev believes that the decision ... is erroneous and has appealed the decision in order to maintain its rights," an InBev spokeswoman said. "We are confident that the complaint is unjustified and that we will be able to complete the proposed transactions with SUN Trade."

Upon completion, InBev would own 75.5% of SUN Interbrew. This would fend off Alfa Group, a Russian conglomerate that aims to increase its 15% stake in SUN Interbrew, Russia's second biggest brewer behind Baltika.

On news of the court ruling earlier this month, Alfa told Reuters that it hoped it would be able to take over SUN Interbrew within a month. InBev's spokeswoman declined to comment on Alfa's statement.
