Well, it seems the lawsuit is left to viewer's wish.
However, Will's source of Genoa tip is highly same as Charlie's source. At season 2 episode 7 named Red Team III, when Rebecca interviews with Sloan about the lawsuit, she insistly asks Sloan "anyone think to ask if Charlie's source and Will's source were the same person?". So, Will wouldn't call the unreliable source again.
Although that, I've checked this episode and I've found that Will hands paper to Jenna and says "it's White House number, just call, don't ask name of the person and give my name". Wish they've had explained all story and connections before it ended.
