Chris Bell is suing the Perry campaign. I took a look at the filed complaint. Robert Black has called the suite, "sour grapes." Well, maybe...kind of...but, technically the Perry campaign had the information but just did not bother to file it as required.
I've worked in heavily regulated industries for years and I can tell you that getting things into regulatory agencies on time is a priority in the business world. If you don't they have a tendency to walk into your building unannounced and start discussing things like "cease and desist" and "fines" and all the things people get fired for if the boss hears about. In politics, there's always an empty threat but with no backbone to actually impose the fine or shut something down. For that reason, I'd say it's not sour grapes but an attempt to introduce accountability into politics. The fact that the suit had to come from Chris Bell is more of an embarrassment to an agency that is supposed to monitor and control campaign spending reports than it is of Chris Bell trying to stir up some shit.
