Asking about a lawsuit at interview?

I was trying to do some prep work for possible interview with a group, and when I googled the name, a malpractice lawsuit came up against it. Reading through it, it did seem pretty egregious what was accused. I don't know the outcome of the case, and I also was unaware a whole group can get sued vs an individual practicing physician. Is it ok to ask about this on phone or in person interview?
