If the stud broke when being removed, either it was cross threaded or over tightened when it was installed. When removing the lug nut, they are doing nothing more than unscrewing a bolt. Therefore, what wrong did they do? The only thing I can think if is if they were tightening it rather than loostening it. But how can you prove that.
I wish I had a better answer, but it sounds like the last person which installed it may have caused the problem.
