While Schengen borders are generally open, countries have the right to shut/restrict their borders with other Schengen countries in certain scenarios.
Has France announced any plans to temporarily reintroduce controls or otherwise restrict entry from other Schengen countries during the 2024 Summer Olympics?
Even is nothing is announced, is there any precedent for similar events within the Schengen zone that make it a possibility?
France among other EU countries has been using Schengen exception clauses to reinstate interior border controls since the 2015 terrorist attacks, and circumventing/overusing them ever since in a continuous series of extension periods.
In 2022 and 2023, the EU court of Justice ruled that these controls could not be made to exceed 6 months in that way unless a new, different serious threat arised.
France's Conseil d'Etat has however ruled against the ECJ since, and French majority politicians have lobbied to loosen the Schengen regulations. In February 2024 an agreement has been reached between EU Council and Parliament to extend the periods to a maximum of two years, renewable for a year.
The new rules will take time to finalize and implement. In the meantime, France currently has temporary reintroduction of border control running until April 2024 due to new terrorist threats, and is likely to renew it again for the Olympics even if there wasn't a specific annoucement about it. That means yes, expect border controls on entry where border police sees fit, especially when travelling by air through airports that have the infrastructure to host a customs check (it even happens in unlikely routes like Belgium -> France for instance).
It is very likely it will renew the controls reintroduction, since those have been reintroduced since 2015 :
Foreseeable cases (Article 25 and 26 of the codified SBC)
For foreseeable events (e.g. sports events), the duration of the border control is limited to 30 days or for the foreseeable duration of the threat, if it exceeds 30 days.
Even is nothing is announced, is there any precedent for similar events within the Schengen zone that make it a possibility?
Except for the above, the European Football cup 2016, which was held in France, had no other specific measures
