So, there's the December 6 ruling. The court has ruled that the questions about whether Hillary attempted to evade FOIA requirements, and questions as to the legal adequacy of searches through emails the State Department had access to, and questions about the good or bad faith in earlier attempts to settle the FOIA case are all valid for further Discovery and review by the court as to the adequacy of the responses to Discovery. The judge also noted that either the State Department officials involved were negligent and incompetent, or they may have colluded with Justice Department officials to stop the inquiry and deceive the court. (We're looking at one pissed-off judge, here. This is the second most angry I've ever seen a US Federal Judge, the most being the Dover case in 2006 where the judge openly accused two defense witnesses of perjury.)
Don't forget that not only could FOIA evasion constitute a felony, there are also potential charges under the Federal Records Act and the Espionage Act. The last are the very charges Comey incorrectly declared Hillary Clinton absolved from because she didn't have the intent to violate the law, which is not a requirement for failing to properly and securely handle classified information under the Espionage Act, and neither is that anything was actually accessed by someone not authorized to do so. All that is required is that the documents were handled in a manner that did not meet the security requirements of the classification level of the document.
