“…. The document or class of documents [sought] must be shown by the applicant to offer a real probability of evidential materiality in the sense that it must be a document or class of which in the ordinary way can be expected to yield information of substantial evidential materiality to the pleaded claim and the defence ….”
“Disclosure is not without its disadvantages. The principal one is that disclosure can be an expensive and burdensome process. The Courts are generally alert to the danger of oppressive disclosure and inappropriate requests for wide ranging disclosure are not infrequently dismissed for being not necessary for the fair disposal of litigation. The burden can not only fall on the party giving disclosure, but also on an opposing party presented with a mass of documentation of marginal relevance. In such a case disclosure can, far from clarifying the issues, operate as a cloud.”
“[156] …… In asylum determinations there are sound reasons why sources who may have valuable information to give to diplomatic missions, international organisations like UNHCR or non-governmental organisations like Amnesty International would wish to do so under conditions of anonymity ….. Providing information to an appellant or his legal team on a confidential basis may thus provide the source with satisfactory protection. [157] Anonymous material is not infrequently relied on by appellants as indicative of deteriorating conditions or general risk. The Tribunal should be free to accept such material but will do its best to evaluate by reference to what, if anything, is known about the source, the circumstances in which information was given and the overall context of the issues it relates to and the rest of the evidence available. [158] The problem is not one of admissibility of such material as forming part of the background data from which risk assessments are made, but the weight to be attached to such data. It is common sense and common justice that the less that is known about a source and its means of acquiring information, the more hesitant should a Tribunal judge be to afford anonymous supported assessment substantial weight, particularly where it conflicts with assessment from sources known to be reliable … [159] The report of the FFM …… was not a model of best practice in a number of respects …. We were, however, satisfied that informants with whom contact was made were selected in good faith by the Mission with the assistance of locally based diplomats. We were also satisfied that ultimately the interlocutors … were content with the final version of the summaries of their information and knew the context in which it was being gathered ….”
“I regard that reasoning as irreproachable.”
“There is no general rule at common law or inspired by the European Convention on Human Rights that uncorroborated anonymous material can never be relied on in a country guidance case or any other case. …. Generally of course the effect of anonymity will go to the weight to be attached to the material in question and care must always be taken in assessing the weight of such material.”
“… Whether it is the duty of the solicitor of one party to civil litigation who in the course of discovery in that litigation has obtained possession of copies of documents belonging to the other party to the litigation to refrain from using the advantage enjoyed by virtue of such possession for some collateral or ulterior purpose of his own not reasonably necessary for the proper conduct of the action on his client’s behalf.”
“Asylum, immigration and kindred appeals are a species of public law proceedings, in which the parties are the citizen (on the one hand) and the State (on the other). I consider that these duties apply with full force in the context of such appeals. To suggest otherwise would be inimical to the administration of justice,”
