The Federal Court said in a statement on Tuesday the “domain name system” ban was proportionate. Gaming officials have since 2019 used network blocks to limit access to the market to Swiss-approved games of chance.
The system means Swiss gamblers can bet online only with Swiss casinos and lotteries that pay tax in the country and that protect people against falling victim to addiction.
German group bet-at-home.com AG had on Monday already revealed the verdict.
In four verdicts released last year, the Federal Administrative Court had ruled against Malta-based Interwetten International Ltd, Videoslots Ltd, bet-at-home Entertainment Ltd, and Lopoca Gaming Ltd in suits against the Swiss Federal Gaming Board seeking to circumvent the ban.
