Bollate. It was established as a comune in its own right in November of that year by the promulgation of a regional law. In 2003 this law was declared unconstitutional by the
Constitutional Court of Italy. The establishment of the new comune was annulled, and Barazate became once more a of Bollate. In May 2004 a new regional law re-established the comune. A ruling in the
Court of Justice of the European Union in 2012 involving the comune of Baranzate declared that Italian legislation on
local taxation constituted on unlawful restriction of freedom of establishment and freedom to provide services, which are among the
fundamental freedoms of the European Union. == Demographics ==
