Can a court order reveal an ssn? Is there any situation where a court might order someone to reveal their ssn? Has this happened and what justification was given?
Can a court order reveal an ssn? Yes, although the legitimacy of such order strongly depends on the claims/charges at issue. That being said, the party may (and should) file a motion to have the records sealed, since the public disclosure --insofar as court filings are public records-- of a SSN is extremely unlikely to advance "the interests of justice" in the claims at issue.
The law, at section 52(4) Data Protection Act 2018 does not expressly require a signature. What is needed is confirmation of one's identity: Where the controller has reasonable doubts about the identity of an individual making a request under section 45, 46 or 47, the controller may— (a) request the provision of additional information to enable the controller to confirm the identity, and (b) delay dealing with the request until the identity is confirmed. One option is to submit the request with an explanation as to why your signature has changed and wait and see if the data controller comes back for additional information. If you can't provide anything more, or they still won't process your request if you do, there's alway the option of appealing to the Information Commissioner's Office
Yes, you can ask but if they don’t they can come in anyway. The law gives them the right to enter in certain circumstances. Notwithstanding, any government employee that disclosed confidential information that they got in the course of their employment could be sued and possibly prosecuted.
You are right, the entry and exit photos are only evidence that you were there. This is something they need to prove so the photos may only be for that. Their statement that you didn’t display a valid ticket/permit is, at present an unevidenced assertion. If you contest this, they will provide evidence that you didn’t (e.g. the actual records they refer to) and you would provide evidence that you did and, if it goes to court, the judge will decide what evidence they prefer. As this is not a criminal matter, they need to prove the offence on the balance of probabilities. However, there are almost certainly administrative remedies which will allow you to contest the fine without going to court. This would involve you sending them a copy of the permit and them assessing whether their belief that you didn’t display it is justified or not.
There are two cases to distinguish: information that the other party does not want to give without court order, and information that the other party may not give without court order. Only the former case matters, of course, since the latter by definition requires a court order. So, if the other party is legally capable of giving the information, but it's commercially not sensible for them, then you'll need to sweeten the deal. And that's business, not a legal question anymore. In other words: there's no legal instrument that's at the same time equal to a court order but also different from one. When you need a court order, there's no alternative to a court order.
An existing law actually prohibits using census data "against" a person, see this recent question. The 5th Amendment ("nor shall be compelled in any criminal case to be a witness against himself") is not interpreted to imply an absolute privilege to not answer, it means that your answer cannot be used against you in a criminal case. You can be compelled to testify "against yourself" if you are granted immunity from prosecution.
No, you are not obligated to provide the requested information. You're out of trial court and into the court of appeals, where the civil discovery rules have basically no effect. If the case gets kicked back to the trial court, you would likely be required to respond truthfully. To cover your bases and look responsible, the most proper thing to do would probably be to respond to the discovery requests, but answer with nothing but an objection to the requests on the basis that the Rules of Civil Procedure do not apply after the case has been dismissed. At that point, the burden is on the other party to make a motion to compel, which he probably won't do. And if he does, I'd expect the court to deny it summarily based on the dismissal.
The warning notice is intended for viewers and participants, not for the court to make its own official record of the proceedings. Presumably, it was this court record that the judge released for educational purposes under his own Order via Twitter. In which case, there has been no contempt of court.
