"the judge asserts there's little value in making those documents available as they won't serve to help the public assess the court's function ..."
I am guessing that the judge is constrained by certain laws and/or procedural rules that determine whether they can officially release this data (eg based on the wording, that docs can only be released if they "help the public assess the court's function"). Because there IS absolutely a huge public interest value in releasing the documents!
Otherwise those IBM executive emails are ripe for a Wikileaks / Panama Papers-style release
