If you feel you are being spied on and want to challenge the government in court you have this to look forward to. Again, what country do we live in? Is this America or some Orwellian land where the government holds all the cards?
The implications of this issue are larger than the crowd that says "I have done nothing wrong so go ahead and spy on me" realizes. If the government can hold court documents and disclose them or change them at their discretion, in what way can our courts be truly autonomous? One of the important functions of a court is to hold public records in matters of law. Legal precident is an important part of our system of justice. Access to the documents, that court decisions are predicated on, are an integral part of our autonomus legal system, and do influence future cases and case law.
