paragraph_text: 2015 migrant crisis
  
  During the migrant crisis of September 2015, Germany announced it was temporarily bringing border controls back in accordance with the provisions on temporary border controls laid down by the Schengen acquis. Such border controls appear to be an attempt to prevent disorder from making the crisis worse.Open borders appeared to have impeded Germany's ability to provide for very large numbers of persons seeking refuge all at once.Germany signals the border controls are only temporary, and only to support an orderly flow of migration into the area.
  
  Other countries, including Austria, Denmark, Slovenia, Hungary, Sweden and Norway have set up border controls in response to the crisis.
  
  In December 2015, Sweden passed a temporary law that allows the government to oblige all transport companies to check that their passengers carry valid photographic identification. The new law came into effect on 21 December 2015 and was valid until 21 December 2018. The government decided that the new rules would apply from 4 January 2016 until 4 July 2016. The law led to the mandatory train change and passage through border control at Copenhagen Airport for travellers between Copenhagen and Sweden, and with a reduction in service frequency. Sweden had introduced border control from Denmark earlier (15 November 2015), but that could not stop the migrant flow, since they have the right to apply for asylum once on Swedish ground. First when the transport companies had to stop foreigners on the Danish side, asylum seekers were efficiently stopped. This caused considerable disruption to the train traffic since the railway station did not have capacity for such checks. These checks lasted until 4 May 2017, after the EU commission declared such checks not acceptable.
  
  On 30 May 2018, when the migrant crisis border controls were still active in some countries, the European Parliament decided to condemn prolonged border checks between Schengen Area member countries. But this was only a statement as the Parliament does not decide this.
