“ ‘harm’ means ill treatment or the impairment of health or development including for example impairment suffered from seeing or hearing the ill treatment of another;” ‘development’ means physical, intellectual, emotional, social or behavioural development; ‘health’ means physical or mental health; ‘ill treatment’ includes sexual abuse and forms of ill treatment which are not physical.”
“[30] In our view, the principle that a litigant should be able to see and hear all the evidence which is seen and heard by a court determining his case is so fundamental, so imbedded in the common law, in the absence of parliamentary authority no judge should override it, at any rate in relation an ordinary civil claim unless (perhaps) all parties to the claim agree otherwise. At least so far as the common law that is concerned, we would accept the submission that this principle represents an irreducible minimum requirement of an ordinary civil trial. Unlike principles such as open justice, or the right to disclosure of relevant documents, a litigant’s right to know the case against him and to know the reasons why he has lost or won is fundamental to the notion of a fair trial. ……. [32] A litigant’s right to disclosure of documents is not a fundamental right in the same way as the right to know the evidence and argument presented to the judge and the reasons for the judge’s decision. Quite apart from this, if PII professional privilege or ‘without prejudice’ privilege is claimed in respect of a relevant document, the trial process itself is not impugned, as it is still fair: all parties are in the same position and none of them can rely on a document. That cannot be said where the trial is conducted partly, let alone wholly, through a closed material procedure. [33] Different considerations may apply where the proceedings do not only concern the interest of the parties to the litigation but they also have a significant effect on a vulnerable third party, or where a wider public interest is engaged. Thus, where the case directly impinges on the interest of a child, it may be justifiable for the court to see a document which is not seen by the parties to the proceedings. In Re K (Infant) …[1965] AC201 , 240-241 Lord Devlin said “where the judge sits purely as an arbiter and relies on the parties for information, the parties have a correlative right that he should act only on information which they have had the opportunity of testing. Where the judge is not sitting purely, or primarily, as an arbiter, but is charged with a paramount duty of protecting one outside the conflict, a rule that is defined for just arbitrament cannot in all circumstances prevail”. [34] More recently, the point was expressed in these terms by Baroness Hale of Richmond in Secretary of State for the Home Department v MB[2001] 1AC 440 paragraph 58: “If…the whole object of the proceedings is to protect and promote the best interests of the child there maybe exceptional circumstances in which disclosure of some of the evidence would be so detrimental to the child’s welfare as to defeat the object of the exercise”. [35] Similarly in Roberts[2005] 2AC 738 paragraph 48 Lord Woolf CJ referred to the Parole Board having “a triangulation of interests: the board’s obligation to the prisoner and its obligation to protect society and as part of the latter of its obligation its obligation to protect third parties so far as it is practical to do so”
