The
Treaty on the Functioning of the European Union ([https://en.wikisource.org/wiki/Consolidated_version_of_the_Treaty_on_the_Functioning_of_the_European_Union 2007]) is one of the primary
Treaties of the European Union, alongside the
Treaty on European Union (
TEU). The TFEU forms the detailed basis of
EU law, by setting out the scope of the
EU's authority to legislate and the principles of law in those areas where EU law operates.
