"Defences based on Article 31(1) of the Refugee Convention (1) It is a defence for a refugee charged with an offence to which this section applies to show that, having come to the United Kingdom directly from a country where his life or freedom was threatened (within the meaning of the Refugee Convention), he — (a) presented himself to the authorities in the United Kingdom without delay; (b) showed good cause for his illegal entry or presence; and (c) made a claim for asylum as soon as was reasonably practicable after his arrival in the United Kingdom." (2) If, in coming from the country where his life or freedom was threatened, the refugee stopped in another country outside the United Kingdom, subsection (1) applies only if he shows that he could not reasonably have expected to be given protection under the Refugee Convention in that other country. (3) In England and Wales and Northern Ireland the offences to which this section applies are any offence, and any attempt to commit an offence, under — … (aa) section 25(1) or (5) of theIdentity Cards Act 2006 ; … (6) 'Refugee' has the same meaning as it has for the purposes of the Refugee Convention. (7) If the Secretary of State has refused to grant a claim for asylum made by a person who claims that he has a defence under subsection (1), that person is to be taken not to be a refugee unless he shows that he is. …"
"To summarise, the main elements of the operation of this defence are as follows: i) The defendant must provide sufficient evidence in support of his claim to refugee status to raise the issue and thereafter the burden falls on the prosecution to prove to the criminal standard that he is not a refugee (section 31 Immigration and Asylum Act 1999 and Makuwa [26]) unless an application by the defendant for asylum has been refused by the Secretary of State, when the legal burden rests on him to establish on a balance of probabilities that he is a refugee (section 31(7) of the Asylum and Immigration Act 1999 and Sadighpour [38] – [40]). ii) If the Crown fails to disprove that the defendant was a refugee (or if the defendant proves on a balance of probabilities he is a refugee following the Secretary of State's refusal of his application for asylum), it then falls to a defendant to prove on the balance of probabilities that a) he did not stop in any country in transit to the United Kingdom for more than a short stopover (which, on the facts, was explicable, see (iv) below) or, alternatively, that he could not reasonably have expected to be given protection under the Refugee Convention in countries outside the United Kingdom in which he stopped; and, if so: b) he presented himself to the authorities in the UK 'without delay', unless (again, depending on the facts) it was explicable that he did not present himself to the authorities in the United Kingdom during a short stopover in this country when travelling through to the nation where he intended to claim asylum; c) he had good cause for his illegal entry or presence in the UK; and d) he made a claim for asylum as soon as was reasonably practicable after his arrival in the United Kingdom, unless (once again, depending on the facts) it was explicable that he did not present himself to the authorities in the United Kingdom during a short stopover in this country when travelling through to the nation where he intended to claim asylum. (section 31(1); Sadighpour [18] and [38] – [40]; Jaddi [16] and [30]). iii) The requirement that the claim for asylum must be made as soon as was reasonably practicable does not necessarily mean at the earliest possible moment (Asfaw [16]; R v MA [9]). iv) It follows that the fact a refugee stopped in a third country in transit is not necessarily fatal and may be explicable: the refugee has some choice as to where he might properly claim asylum. The main touchstones by which exclusion from protection should be judged are the length of the stay in the intermediate country, the reasons for delaying there and whether or not the refugee sought or found protection de jure or de facto from the persecution from which he or she was seeking to escape (Asfaw [26]; R v MA [9]). v) The requirement that the refugee demonstrates 'good cause' for his illegal entry or presence in the United Kingdom will be satisfied by him showing he was reasonably travelling on false papers (ex parte Adimi at 679 H)."
"… There are, however, several components that contribute to the interests of justice. The court will have in mind the public interest in the proceedings of the court generally, in particular in the finality of Crown Court judgments, the interests of other litigants, the efficient use of resources and good administration. However, the public interest embraces also, and in our view critically, the justice of the case and the liberty of the individual. …"
