1928 Convention on Asylum ------------------------- The [1928 Convention on Asylum](https://www.refworld.org/docid/3ae6b37923.html) was signed by Ecuador (but obviously not by the UK for geographical reasons). It says > Signed in Havana, February 20, 1928, at the Sixth International Conference of American States ... > Article 1.- It is not permissible for States to grant asylum in **legations**, warships, military camps or military aircraft, to persons accused or condemned for common crimes, or to deserters from the army or navy. > Persons accused of or condemned for **common crimes** taking refuge in any of the places mentioned in the preceding paragraph, shall be surrendered upon request of the local government. Which suggests someone accused of the common crime of breaking bail who is sheltering in a legation should be surrendered. It doesn't say anything about withdrawing asylum though. --- 1951 Convention Relating to the Status of Refugees -------------------------------------------------- Someone who has committed a serious crime is excluded: > F. The provisions of this Convention shall not apply to any person with respect to whom there are serious reasons for considering that: ... > (b) he has committed a serious non-political crime outside the country of refuge prior to his admission to that country as a refugee; A crime punishable by a year in prison may be serious enough. Of course this also does not apply to Assange since he was not in the country of refuge. Being moved from one part of London to another part of London does not constitute expulsion from a country. Certainly not from Ecuador. Granting UK police permission to enter a part of UK territory to apply UK law also *probably* does not technically constitute expulsion from the building *by those granting permission*.
