“Save in cases involving criminality, the decision maker must not take a decision in relation to the parent or primary carer of a British Citizen child where the effect of that decision would be to force that British child to leave the EU, regardless of the age of that child. This reflects the European Court of Justice Judgment in Zambrano . … Where a decision to refuse the application would require a parent or primary carer to return to a country outside the EU, the case must always be assessed on the basis that it would be unreasonable to expect a British Citizen child to leave the EU with that parent or primary carer. In such cases it will usually be appropriate to grant leave to the parent or primary carer, to enable them to remain in the UK with the child, provided that there is satisfactory evidence of a genuine and subsisting parental relationship. It may, however, be appropriate to refuse to grant leave where the conduct of the parent or primary carer gives rise to considerations of such weight as to justify separation, if the child could otherwise stay with another parent or alternative primary carer in the UK or in the EU. The circumstances envisaged could cover amongst others: •. criminality falling below the thresholds set out in paragraph 398 of the Immigration Rules; •. a very poor immigration history, such as where the person has repeatedly and deliberately breached the Immigration Rules. In considering whether refusal may be appropriate the decision maker must consider the impact on the child of any separation. If the decision maker is minded to refuse, in circumstances where separation would be the result, this decision should normally be discussed with a senior caseworker and, where appropriate, advice may be sought from the Office of the Children’s Champion on the implications for the welfare of the child, in order to inform the decision.”
