of consumers in Budweiser firm Anhesuer's hometown of St Louis
is seeking to block the deal outright.
The lawsuit claims : "If Inbev is allowed to purchase Anheuser, there no longer would be any significant major potential competitor to influence pricing and ≠marketing practices in the US."
Inbev has claimed
the proposed $52 billion purchase won't infringe competition laws because Inbev is only a niche player in the US market to date, adding only a small amount in sales to Anheuser's existing market share.
The US Justice Department is already reviewing the legality of the deal.
If it goes through, the acquisition will bring together a portfolio including Budweiser, Stella Artois and Beck's.
