6.11.2013 Official Journal of the European Union L 295/1 (Legislative acts) REGULATIONS REGULATION (EU) No 1051/2013 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 22 October 2013 amending Regulation (EC) No 562/2006 in order to provide for common rules on the temporary reintroduction of border control at internal borders in exceptional circumstances THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION, Having regard to the Treaty on the Functioning of the European Union, and in particular Article 77(1) and (2) thereof, Having regard to the proposal from the European Commission, After transmission of the draft legislative act to the national parliaments, Acting in accordance with the ordinary legislative procedure (1), Whereas: The creation of an area in which the free movement of persons across internal borders is ensured is one of the main achievements of the Union. In an area without internal border control, it is necessary to have a common response to situations seriously affecting the public policy or internal security of that area, of parts thereof, or of one or more Member States, by allowing for the temporary reintroduction of internal border control in exceptional circumstances, but without jeop- ardising the principle of the free movement of persons. Given the impact that such measures of last resort may have on all persons having the right to move within the area without internal border control, the conditions and procedures for reintroducing such measures should be laid down, in order to ensure that they are exceptional and that the principle of proportionality is respected. The scope and duration of any temporary reintroduction of (1) Position of the European Parliament of 12 June 2013 (not yet published in the Official Journal) and Decision of the Council of 7 October 2013. such measures should be restricted to the bare minimum needed to respond to a serious threat to public policy or internal security. Free movement of persons within the area without internal border control is a key Union achievement. As free movement of persons is affected by the temporary reintroduction of internal border control, any decision to reintroduce such control should be taken in accordance with commonly agreed criteria and should be duly notified to the Commission or be recommended by a Union institution. In any case, the reintroduction of internal border control should remain an exception and should only be effected as a measure of last resort, for a strictly limited scope and period of time, based on specific objective criteria and on an assessment of its necessity which should be monitored at Union level. Where a serious threat to public policy or internal security requires immediate action, a Member State should be able to reintroduce border control at its internal borders for a period not exceeding ten days. Any prolongation of that period needs to be monitored at Union level. The necessity and proportionality of reintroducing internal border control should be balanced against the threat to public policy or internal security triggering the need for such reintroduction, as should alternative measures which could be taken at national or Union level, or both, and the impact of such control on the free movement of persons within the area without internal border control. The reintroduction of internal border control might exceptionally be necessary in the case of a serious threat to public policy or to internal security at the level of the area without internal border control or at national level, in particular following terrorist incidents or threats, or because of threats posed by organised crime.
