“In one class of case there is a long-standing doctrine that collateral challenge is not to be allowed: where there is some unknown flaw in the appointment or authority of some officer or judge. The acts of the officer or judge may be held to be valid even though his own appointment is invalid and in truth he has no legal power at all.”
“It may well be that the principle which validates the acts of a judge de facto cannot be invoked for their own protection by any who wilfully abuse the office, still less by mere usurpers.”
“But what if the court usher had been persuaded to sit and everyone in court had behaved as if he were entitled to do so? There must come a point at which, whatever the public perception, there is no basis for applying the de facto doctrine. The dividing line between what is and is not sufficient ‘colour’ in borderline cases may not be as clear as one would like, but fortunately the point does not arise for decision here.”
“In the present state of authority the position of the usurper, in the sense of someone who discharges an office in the actual or constructive knowledge that he has no title to it, is in my view uncertain. If the purpose of the de facto doctrine is the maintenance of stability and confidence in the legal system and the prevention of disputes about the formalities of appointment, it might well be said that a sufficiently clearly reputed tenure of office should not be open to challenge even on the ground of the purported officer’s knowledge of his own incapacity. Yet, as Mr Sales’ response on behalf of the Lord Chancellor confirms, it goes entirely against the grain to validate the acts of someone who knows, even if the world does not, that he is not qualified to hold the office he is exercising.”
“The Judge told me that he was appointed as a Judge of the Technology and Construction Court (the “TCC”) in July 2000, This was his first full-time judicial appointment. The Judge recalled that, on his appointment, the Judge in charge of the TCC lists (then Mr Justice Dyson) explained that, during the times when the Judge had unexpected capacity in his TCC list, he would be expected to volunteer to assist in the Queen’s Bench Division or the Chancery Division of the High Court. The Judge explained that he understood he did have authority to sit in the QBD and Chancery Division by virtue of his appointment as a TCC judge alone and that no further authorisation was required.”
“The application of the de facto doctrine is, however, limited to validating acts which are taken under invalid authority: it does not validate the authority under which the acts took place.”
“In the determination of his civil rights and obligations or of any criminal charge against him, everyone is entitled to a fair and public hearing within a reasonable time by an independent and impartial tribunal established by law.”
“(1) It is unlawful for a public authority to act in a way which is incompatible with a Convention right. (2) …. (3) In this section “public authority” includes … a court or tribunal …”
“An officer de facto is one whose acts, though not those of a lawful officer, the law, upon principles of policy and justice, will hold valid so far as they involve the interests of the public and third persons, where the duties of the office were exercised [irregularly].”
“That the judicial organisation in a democratic society must not depend on the discretion of the Executive, but that it should be regulated by law emanating from Parliament.”
“Everyone is entitled to a fair and public hearing within a reasonable time by an independent and impartial tribunal previously established by law.”
