As the UK Supreme Court’s much anticipated decision in KO (Nigeria) this Wednesday draws near, here’s a quick rundown of some key cases on this issue and some free resources, all from Law, mostly.
KO (Nigeria) will consider wheter parental misconduct (ie. criminal convictions and adverse immigration histories) can be considered when deciding whether settled children should be expected to leave the UK or to be separated from parents who are being removed.
Both the Upper Tribunal and the Court of Appeal have answered ‘yes’ to the above question, although one Lord Justice (Elias) expressed some misgivings. 
It seems unlikely to me that the Supreme Court will completely reverse the decisions of the lower judges. However, as Lady Hale once said quotably:
Children can sometimes surprise one.
(§ 37, ZH (Tanzania) v Secretary of State for the Home Department  UKSC 4)
Children’s rights cases can be hazardous to predict and I hope to be proven wrong about KO (Nigeria). Either way, the Supreme Court will hopefully provide some much needed further guidance on the tension between the principle that children should not be held responsible for the sins of their parents and the current notion that, when assessing the effect of removal on a settled child, parental misconduct is a relevant factor in the balance.
