Interesting to read that the Swiss tribunal has decided today that the Lex Koller restrictions on second homes will take effect from March 2012 ie all of the 1000s of building applications made during the remainder of 2012 may not now be valid.
linked to that it seems that Helvetia Nostra can appeal building applications directly.
Views on what this all means for current owners, economic activity in the mountain resorts, the permanent inhabitants of the villages etc are mixed. Answers on a postcard...
