EU rules foresee that countries in the passport-free Schengen zone can only establish temporary border controls under exceptional circumstances. In December 2015, Sweden introduced internal border controls. Please see the 2018 AIDA report for a historical background and legal aspects on the border controls.
Internal border controls were prolonged during 2019. The government decided in October 2019 to continue border control at the internal border for another six months. The controls will continue until 12 May 2020. The decision is based on the government's assessment that there is still a threat to public order and internal security in Sweden. The security police also believes that the terrorist threat level is still high. There are also shortcomings in the control of the external borders around Schengen, which means that Sweden must maintain its internal border controls. The checks are concentrated in southern and western Sweden and the Öresund bridge.
In its appropriations directions to the Police Authority for 2020, the government states that it shall prioritise and take the necessary measures to be able to carry out a fully functioning regular border control at external borders during all the months of the year. In addition, the authority shall continue to develop its preparedness and ability to conduct an appropriate border control at internal borders if necessary.
