I have referred to the opinions expressed in Rees v. Kratzmann [2] that the discretionary control of the proceedings by the court is a safeguard against the use of the section in an oppressive or unjust way. Although in form the discretion is a discretion as to allowing questions to be put and not as to compelling them to be answered, it seems clear that if a question be asked and objection be taken, on this or on any other ground, the court has a discretion to decide whether or not the question is a proper one and if it decides it is not, no answer need then be given. This is a judicial discretion, which may in appropriate cases be reviewed by an appellate court. In particular circumstances if the court declined to require an answer because of a claim that it might incriminate the witness, it might be held that the discretion had not been properly exercised and that the court should reconsider that decision. See In re Paget [3] . I think that in deciding whether a particular line of questioning, to which objection is taken, should be allowed, the court may sometimes take into account the fact, if it be a fact, that the answers might tend to incriminate the witness. But in my opinion it would not be in accordance with the plain language of the section to hold that the possibility of self-incrimination must be regarded by the court as decisive against allowing a question to be put. This can never be more than one factor, to be considered with others, in deciding as a matter of discretion whether to allow or to disallow a question. Indeed, in many cases, the possibility or even the certainty that an answer would incriminate the person being examined would not itself provide a sufficient reason for disallowing the question, since questions will normally be directed to the investigation of all the relevant facts in order that it may be ascertained whether or not there has been fraud or concealment of material facts. I think it is the intention disclosed by the section that any questions which will be of real assistance towards the fulfilment of that purpose should be answered. There may, however, be some cases in which it appears to the court that a particular question or a particular line of questioning has such a remote or doubtful bearing upon the investigation with which the court is concerned that the harm that may be done to the individual will outweigh any benefit to be obtained and that, therefore, that question or line of questioning ought to be disallowed. The section gives to the court an unqualified discretion. In the present case it is not necessary to examine more fully the manner in which this discretion should be exercised. No argument has here been raised and none could be successfully raised that the learned judge conducting the examination exercised upon wrong principles a discretion vested in him. The argument is that he had no power at all to direct that the questions be answered and, in my opinion, this argument cannot be accepted.
