Following a referendum on March 10, 1996, Romansh was recognized as a partial official language of Switzerland alongside German, French, and Italian in article 70 of the federal constitution. According to the article, German, French, Italian, and Romansh are national languages of Switzerland. The official languages are declared to be German, French, and Italian, and Romansh is an official language for correspondence with Romansh-speaking people. This means that in principle, it is possible to address the federal administration in Romansh and receive an answer in the same language. More precisely, under section 2.6.3 of the Federal Act on the National Languages and Understanding between the Linguistic Communities, Romansh speakers may address the administration in any variety of Romansh, though they will receive a response in Rumantsch Grischun.
