“(1) The best interests of a child are an integral part of the proportionality assessment underArticle 8 ECHR ; (2) In making that assessment, the best interests of a child must be a primary consideration, although not always the only primary consideration; and the child’s best interests do not of themselves have the status of the paramount consideration; (3) Although the best interests of a child can be outweighed by the cumulative effect of other considerations, no other consideration can be treated as inherently more significant; (4) While different judges might approach the question of the best interests of a child in different ways, it is important to ask oneself the right questions in an orderly manner in order to avoid the risk that the best interests of a child might be undervalued when other important considerations were in play; (5) It is important to have a clear idea of a child’s circumstances and of what is in a child’s best interests before one asks oneself whether those interests are outweighed by the force of other considerations; (6) To that end there is no substitute for a careful examination of all relevant factors when the interests of a child are involved in an Article 8 assessment; and (7) A child must not be blamed for matters for which he or she is not responsible, such as the conduct of a parent.”
