Attorney fees have been awarded in a case brought by STS Energy Partners against the FERC. What is interesting in the case, is that the court found the documents had a public interest but that they also commercially benefited the plaintiffs. However, the court, in its discretion found that the agencies actions in withholding the documents prior to litigation and the public interest in the documents were enough to merit an award of attorney's fees. It will be interesting to see if the government accepts the decision or files an appeal of it.
