“On the other hand, we have also made it clear that the act of producing documents in response to a subpoena may have a compelled testimonial aspect. We have held that ‘the act of production’ itself may implicitly communicate ‘statements of fact.’ By ‘producing documents in compliance with a subpoena, the witness would admit that the papers existed, were in his possession or control, and were authentic’ [citing United States v Doe, 465 US 605 at 613 (1984)]. Moreover ... when the custodian of documents responds to a subpoena, he may be compelled to take the witness stand and answer questions designed to determine whether he has produced everything demanded by the subpoena. The answers to those questions, as well as the act of production itself, may certainly communicate information about the existence, custody, and authenticity of the documents.”
“What prejudice can an accused be said to suffer from being forced to confront evidence ‘derived’ from his or her compelled testimony, if that accused would have had to confront it even if the power to compel testimony had not been used against him or her?”
“I do not think it can be said that the use of such evidence would be equivalent to forcing the accused to speak against himself or herself; once the derivative evidence is found or identified, its relevance and probative weight speak for themselves. The fact that such evidence was found through the evidence of the accused in no way strengthens the bearing that it, taken by itself, can have upon the questions before the trier of fact … In my view, derivative evidence that could not have been found or appreciated except as a result of the compelled testimony … should in the exercise of the trial judge’s discretion be excluded since its admission would violate the principles of fundamental justice. …I do not think such exclusion should take place if the evidence would otherwise have been found and its relevance understood. There is nothing unfair in admitting relevant evidence of this kind...”
“The right not to incriminate oneself is primarily concerned, however, with respecting the will of an accused person to remain silent. As commonly understood in the legal systems of the contracting parties to the Convention and elsewhere, it does not extend to the use in criminal proceedings of material which may be obtained from the accused through the use of compulsory powers but which has an existence independent of the will of the suspect such as, inter alia, documents acquired pursuant to a warrant …”
“…the tendency to expose to a penalty would be increased if the documents in question were to be validated and connected with the R.T.Z. companies by sworn evidence, as opposed to being, as they are now, pieces of paper found in a file.”
“I regard the privilege against self-incrimination exercisable in civil proceedings as an archaic and unjustifiable survival from the past when the court directs the production of relevant documents and requires the defendant to specify his dealings with the plaintiff’s property or money.”
“I can for myself see no argument in favour of the privilege against producing a document the contents of which may go to show that the holder has committed a criminal offence. The contents of the document will speak for itself and there is no risk of the false confession which underlies the privilege against having to answer questions that may incriminate the speaker. The rule may once have been justified by the fear that without it an accused might be tortured into production of documents but those days are surely past and this consideration cannot apply in the context of a civil action.”
