Switzerland–European Union relations
Switzerland is not a member state of the European Union (EU). It is associated with the Union through a series of bilateral treaties in which Switzerland has adopted various provisions of European Union law in order to participate in the Union's single market, without joining as a member state. Among Switzerland's neighbouring countries, all but one are EU member states.
Letter regarding membership negotiations
The European single market, also known as the European internal market or the European common market, is the single market comprising mainly the 27 member states of the European Union (EU). With certain exceptions, it also comprises Iceland, Liechtenstein, Norway, and Switzerland. The single market seeks to guarantee the free movement of goods, capital, services, and people, known collectively as the "four freedoms". This is achieved through common rules and standards that all participating states are legally committed to follow.
In Schmidberger v Austria, protests blocked trucks for goods through the Austrian Alps on the Brenner Autobahn. The Court of Justice recognised fundamental rights take priority over free trade.
The Court of Justice in Centros Ltd held that people can establish a UK company or any other, to do business EU-wide, but must comply with proportionate requirements in the public interest, such as the basic labour right to a voice at work.

In Angonese the Court of Justice gave "horizontal direct effect" to free movement, so a bank could not refuse employment to a worker who lacked a language certificate that could only be obtained in Bolzano.
