eunion1-5, Exercise 3: Border checks and Schengen

Model answer (one possible answer):

For the claim (long-running checks undermine Schengen): checks that are repeatedly extended stop being "temporary" and erode a core achievement of the Union; they raise costs and delays for travellers and workers who cross borders daily.

Against the claim: the rules expressly allow temporary checks for serious threats to public order or security, so using them shows the system working as designed; states argue they need to be able to respond to security concerns and irregular migration.

Both sides describe the same facts. This course reports the arguments and does not settle them.
