“These authorities show that there is no general rule that a case needs to be ‘exceptional’ before a new point will be allowed to be taken on appeal. Whilst an appellate court will always be cautious before allowing a new point to be taken, the decision whether it is just to permit the new point will depend upon an analysis of all the relevant factors. These will include, in particular, the nature of the proceedings which have taken place in the lower court, the nature of the new point, and any prejudice that would be caused to the opposing party if the new point is allowed to be taken.”
“62. The legislation must not only have a legitimate policy objective. It must also satisfy a ‘proportionality’ test. The court must decide whether the means employed by the statute to achieve the policy objective is appropriate and not disproportionate in its adverse effect. This involves a ‘value judgment’ by the court, made by reference to the circumstances prevailing when the issue has to be decided. It is the current effect and impact of the legislation which matter, not the position when the legislation was enacted or came into force. (I interpose that in the present case no suggestion was made that there has been any relevant change of circumstances since the Consumer Credit Act was enacted.) 63. When a court makes this value judgment the facts will often speak for themselves. But sometimes the court may need additional background information tending to show, for instance, the likely practical impact of the statutory measure and why the course adopted by the legislature is or is not appropriate. Moreover, as when interpreting a statute, so when identifying the policy objective of a statutory provision or assessing the ‘proportionality’ of a statutory provision, the court may need enlightenment on the nature and extent of the social problem (the ‘mischief’) at which the legislation is aimed. This may throw light on the rationale underlying the legislation. 64. This additional background material may be found in published documents, such as a government white paper. If relevant information is provided by a minister or, indeed, any other member of either House in the course of a debate on a Bill, the courts must also be able to take this into account. The courts, similarly, must be able to have regard to information contained in explanatory notes prepared by the relevant government department and published with a Bill. The courts would be failing in the due discharge of the new role assigned to them by Parliament if they were to exclude from consideration relevant background information whose only source was a ministerial statement in Parliament or an explanatory note prepared by his department while the Bill was proceeding through Parliament. By having regard to such material the court would not be 'questioning' proceedings in Parliament or intruding improperly into the legislative process or ascribing to Parliament the views expressed by a minister. The court would merely be placing itself in a better position to understand the legislation. 65. To that limited extent there may be occasion for the courts, when conducting the statutory ‘compatibility’ exercise, to have regard to matters stated in Parliament. It is a consequence flowing from the Human Rights Act. The constitutionally unexceptionable nature of this consequence receives some confirmation from the view expressed in the unanimous report of the parliamentary Joint Committee on Parliamentary Privilege (1999) (HL Paper 43-I, HC 214-I), p 28, para 86, that it is difficult to see how there could be any objection to the court taking account of something said in Parliament when there is no suggestion the statement was inspired by improper motives or was untrue or misleading and there is no question of legal liability.”
“142. The questions of justification and proportionality involve a sociological assessment – an assessment of what are the needs of society. This in part involves a legal examination of the content and legal effect of the relevant provision. But it also involves consideration of what is the mischief, social evil, danger etc which it is designed to deal with. Often these matters may already be within the knowledge of the court. But equally there will almost always be other evidentially valuable material which can be placed before the court which is relevant, such as reports that have been made, statistics that have been collected, and so on. Oral witnesses may have important evidence to give. To exclude such evidential material from the case merely because it is to be found in some statement made in Parliament is clearly wrong, particularly if ministerial statements made outside Parliament were already being relied on.”
“It is not necessary to hold a state trial into successive government’s housing policies in order to balance the public and private issues to which article 8 gives rise.”
