Around 23 June 2015 during the European refugee and migrant crisis, Hungary considered itself overburdened with asylum applications after receiving 60,000 "illegal immigrants" that year and announced to no longer receive back applicants who had crossed the borders to other EU countries and were detained there, as they should according to the 'Dublin' regulation, due to unspecified "technical reasons", thus practically withdrawing from that Dublin regulation. On 24 August 2015, Germany therefore decided to make use of the "sovereignty clause" to process Syrian asylum applications for which it would not be responsible under the criteria of the Regulation. On 2 September 2015, the Czech Republic also decided to offer Syrian refugees who had already applied for asylum in other EU countries and who had reached the country to either have their application processed in the Czech Republic (i. e. get asylum there) or to continue their journey elsewhere.
