The European Parliament has asked the Swiss government to revoke a "discriminatory and unlawful" decision to reimpose quotas on long-term residence permits for Polish, Lithuanian, Latvian, Estonian, Slovene, Slovak, Czech and Hungarian citizens.
In a resolution adopted by MEPs on 24th May 2012, the Parliament highly regretted the reintroduction of quotas restricting the free movement of people, which was the subject of an agreement between the EU and Switzerland in 1999.
The Parliament described the measure as "discriminatory and unlawful" because it targets EU citizens on the basis of their nationality.
There is no legal ground to allow this in the existing treaties between Switzerland and the EU, MEPs said.
Concerned that the Swiss Federal Council was considering further restrictive measures, MEPs said the EU and Switzerland should improve cooperation to ease their citizens' free movement.
The Parliament also asked the European Commission to urgently raise the issue with the Swiss government.
