In a lawsuit started by two gamblers, Michael Voight and Mario Cisneros, in which the pair claimed they each individually lost significant amounts of money gambling at search engine sponsored casinos, a California judge ruled that the case would not be dismissed.

Of the search engines targeted in the suit, Google and Yahoo are the most highly profiled, with a total of ten accused search engines altogether.  The suit itself is validated by the U.S. government's crackdown on search engines who advertise for online casino gambling websites.  In the recent past it was agreed upon that the major search engines would meet the government's demand.  However, the lawsuit claims that websites were still being advertised by the search engine's pay-per-click system, which charges website owners - in this case, online casino owners - for every click brought to the website through the search engine.

A spokesperson for Google stated the company no longer takes payments from online gambling sites, but only display's casino gambling websites in its normal search engine results, which has not been deemed illegal.
