Various international human rights instruments prohibit the collective expulsions of aliens, including art. 4 of Protocol n° 4 to the ECHR. The text of this provision is, however, quite vague. It merely states that ‘Collective expulsion of aliens is prohibited’. The ECtHR has consistently ruled in several cases like Conka that the prohibition of collective expulsions is infringed by ‘any measure compelling aliens, as a group, to leave a country, except where such a measure is taken on the basis of a reasonable and objective examination of the particular case of each individual alien of the group’. Collective expulsions take place when two constitutive elements are cumulatively met: the aliens are (1) expelled together with other aliens in a similar situation, (2) without due examination of their own individual situations.
