Online betting companies including BWIN Interactive Entertainment and Fluxx are gearing up to file a legal complaint against German state monopoly on lotteries and most forms of betting, law firm Hambach & Hambach head Wulf Hambach said.

Hambach said that he represents about 20 of the world’s biggest betting companies, according to the local newspaper the Die Welt.

Germany’s states earlier this month ratified an accord solidifying their monopoly on lotteries, online gambling and most forms of sports betting in Germany.

The accord will effectively ban private betting companies from operating in the country from this week.
