Border Controls in Times of the Corona Epidemy

States can resort to extraordinary measures in times of crisis, but discretionary powers are limited. Daniel Thym analysis the wave of border controls and travel restrictions at the internal and external borders of the Schengen arera that have been implemented in recent days in a blogpost for the Odysseus Network ('Travel Bans in Europe: A Legal Appraisal - Part I & Part II') and a previous contribution in German for Legal Tribune Online (’Grenzkontrollen wegen Coronavirus: Wer noch reisen darf, und warum’). He shows that states cannot simply close borders as long as internal mobility remains intact. Moreover, the scope and conditions of the external travel ban should be carified by the EU institutions.
