There are non-refoulement[1] clauses in international refugee law that 181 countries around the world are bound to, I believe.
In previous cases[2] where people are deported whilst seeking asylum the UNHCR has said:
> UNHCR denounced the move as a violation of the "non-refoulement" policy that prohibits the forced return of asylum seekers to areas where they could face danger – a cornerstone of international refugee protection.
> "We cannot accept that these asylum seekers were deported without a chance to explain their case,"
In my opinion, for the rule of law to stand, the asylum process must conclude before he gets deported.
