Not the individual cases that Walmart has been dealing with, but the large class action suit that was being put forward on the general principle of so many individual cases of sexual discrimination by the company.
The case was dismissed on the grounds that it failed to meet the technical requirement for being a class action as each individual case was different and there was not enough similarity between the claims.
WalMart will be mightily relieved at this outcome as it could have led to a massive lawsuit. Not to mention other large companies could also have faced major lawsuits due to the precedents set had they allowed it to go ahead.
More on the story here.
I do sometimes wonder if the reasons these cases go ahead are purely monetary and nothing to do with the general behaviour across the board.
