" 441.—(1) If on an application made— (a) in England, to a judge of the High Court in chambers by the Director of Public Prosecutions, the Board of Trade or a chief " officer of police; or (b) in Scotland, to one of the Lords Commissioners of Justiciary by the Lord Advocate; there is shown to be reasonable cause to believe that any person has, while an officer of a company, committed an offence in connection with the management of the company's affairs and that evidence of the commission of the offence is to be found in any books or papers of or under the control of the company, an order may be made— (i) authorising any person named therein to inspect the said books or papers or any of them for the purpose of investigating and obtaining evidence of the offence; or (ii) requiring the secretary of the company or such other officer thereof as may be named in the order to produce the said books or papers or any of them to a person named in the order at a place so named. (2) . . . . (3) The decision of a judge of the High Court or of any of the Lords Commissioners of Justiciary on an application under this section shall not be appealable."
"What "could be plainer than that?"
"No court or " tribunal has any jurisdiction to make an error of law on which the decision " of the case depends."
" No appeal shall lie... (d) from the decision of the High Court or of any judge thereof where it is provided by any Act that the decision of any court or judge, the jurisdiction of which or of whom is now vested in the High Court, is to be final."
" Having come to that limited construction of the words * an offence "
" In my opinion [section 441(3)] is not a bar to the appeal to this court. There are many cases now which show that if a judge misconstrues a statute by giving himself jurisdiction when he has none or by refusing jurisdiction when he has it, then he makes an error which goes to the "jurisdiction; and there is an appeal to this court, no matter how wide the words which seem to exclude it."
" It seems to me that in this case, if the judge made an error of law *' in construing the words of the section—if he construed the words 'an offence', etc., too narrowly—then he made an error of law which "made him refuse jurisdiction when he ought to have entertained it. So the appeal can be entertained here in this court."
"... the distinction between an error which entails absence of jurisdiction— and an error made within the jurisdiction—is very fine. So fine indeed that it is rapidly being eroded. Take this very case... [The judge's] error can be described on the one hand as an error which went to his jurisdiction ... By holding that it was not a ' structural alteration ... or addition' he deprived himself of jurisdiction to determine those matters. On the other hand,... it can plausibly be said that he had jurisdiction to inquire into the meaning of the words ... and that his wrong inter-pretation of them was only an error within his jurisdiction, and not an *' error taking him outside it. .... "
" The judge is considering the words... which he ought to consider. "
'The decision of a judge of the High Court.., 'on an application under this section shall not be appealable.'
"... the determination by the commission of any application made to them under this Act shall not be called in question in any court of law."
" It is a principle not by any means to be whittled down that the subject's recourse to Her Majesty's courts for the determination of his rights is not to be excluded except by clear words."
" The position under the Judicature Act of the Court of Appeal is very peculiar. When an appeal comes to them as to costs awarded by the discretion of a judge, they cannot exercise their discretion instead of his unless leave to appeal from his order as to costs has been given by him. By a long series of decisions the Court of Appeal has held that that does not prevent them upsetting what the judge has done if they "can find that he had no proper materials on which his discretion was exercised."
