It does not explicitly state that we have to treat them as asylum seekers or refugees either or prohibit us from taking a dim view of travelling through multiple safe countries. It merely holds that it is not an automatic relinquishing of refugee status. Our stance of travelling via safe third countries negatively impacting the liklihood of asylum claims being considered is not incompatible with the treaty. And the UK's criminal law is what determines whether something is illegal in this country, not an international treaty. A refugee under the comvention is someone facing persecution in their home country based on their race, religion, nationality, political opinion or other characteristic likely to put them at risk. So as ive said, stepping off a boat and saying "i'm claiming asylum give me a lawyer" does not automatically just dissappear black and white uk law into a puff of smoke.
