The re-introduction of intra-Schengen state border controls has been a constant feature of the area since the abolition of those controls in 1995. The seriousness of the controls introduced and the justifications which have been put forward for them have varied substantially. At the moment there are three overlapping regimes of temporarily reintroduced border controls in the area: those reintroduced to counter terrorism, those reintroduced to counter so-called secondary movements (the movement of people seeking international protection within the Schengen area) and those introduced to counter the spread of COVID-19. The article examines the three frameworks of temporary controls, the justifications provided by states using them for their operation, and the response of the EU institutions.

自 1995 年取消这些控制以来，重新引入申根国家内部边界控制一直是该地区的一个不变特征。引入的控制的严重性和为它们提出的理由有很大差异。目前，该地区暂时重新引入了三个重叠的边境管制制度：为反恐而重新引入的，为打击所谓的二次流动（在申根地区寻求国际保护的人的流动）而重新引入的，以及为反恐而引入的。COVID -19的传播。本文审视了临时控制的三个框架、使用它们进行操作的国家提供的理由，以及欧盟机构的回应。
