The move, currently being debated in the Greek Parliament, would halt asylum registration for three months and allow for the return of new arrivals without assessing their claims. It follows a recent rise in landings on the southern islands of Gavdos and Crete.

While acknowledging the strain of managing new arrivals, UNHCR said such measures must remain within the boundaries of international and European law.

“States have the right to manage borders and address irregular migration,” the agency said in a statement. “Controlling a State’s borders, however, must be in line with international and European law.”

A fundamental right

The right to seek asylum, UNHCR underscored, is “a fundamental human right enshrined in international, European and national law – and applies to everyone regardless of how or where they arrive in a country.”

“Even at times of migratory pressure,” the statement continued, “States must ensure that people seeking asylum have access to asylum procedures.”

The proposed Greek legislation would deny asylum seekers the ability to lodge applications and instead provide for their return, prompting fears of so-called refoulement – the forced return of individuals to countries where they may face threats to life or freedom.
