I read earlier that the Italian prime minister said that he wasn’t going to suspend Schengen as it was disproportionate ..seems like some other EU countries may have a different view!
I've just read how the French health minister is 'monitoring the situation' and is meeting other EU health ministers this week to discuss the situation. I'm reading this as including a frank discussion over the border issue.
Politically I think if border areas are asking their own countries to close the borders and there are other incidents of suspected cases coming from the region (we have the Romania case and this Austrian train) then pressure to close the borders is going to be very strong and it will happen.
Given that Italy were the first European country to stop flights from China, its going to be a difficult thing for them to argue against tbh.
Schegen allows for emergency suspension and reinstatement of borders:
ec.europa.eu/home-affairs/what-we-do/policies/borders-and-visas/schengen/REINTRODUCTION-BORDER-CONTROL_EN
The Schengen Borders Code provides Member States with the capability of temporarily reintroducing border control at the internal borders in the event that a serious threat to public policy or internal security has been established.
The reintroduction of border control at the internal borders must remain an exception and must respect the principle of proportionality. The scope and duration of such a temporary reintroduction of border control at the internal borders is limited in time and should be restricted to the bare minimum needed to respond to the threat in question. Reintroducing border control at the internal border should only ever be used as a measure of last resort.
The reintroduction of border control is a prerogative of the Member States. The Commission may issue an opinion with regard to the necessity of the measure and its proportionality but cannot veto such a decision if it is taken by a Member State.
At the moment the Italian government is arguing it wouldn't be proportionate to reinstate border controls whilst simultaneously declaring a state of emergency and locking down 50,000 people.
It's an untenable position.
Fully expect border checks to be put up in France, Austria and Switzerland in the coming days.
Those countries can not afford not to be seen to do so because it will be politically damaging to them not to, due to public fears.
