CETA stands for Comprehensive Economic Trade Agreement and is a free trade agreement between EU and Canada. All EU member states approved the treaty, the European Parliament approved the deal and it got operative in 2017. When the CETA deal was signed the EU praised the deal and said that everything would become fantastic because of CETA.
A PRIVATE COURT
In the CECA-treaty we have the now famous mechanism called Dispute Resolution Mechanism. This is a mechanism which bypass a nations own court system and creates a supranational court system.
THE LISBON TREATY
The Lisbon Treaty was approved by the European Parliament in 2008 and entered into force in December 2009. One thing the Lisbon Treaty does is that individual EU member states can no longer make trade agreements with other countries, EU makes the international treaties for them. The Lisbon Treaty is more or less the Constitution of the European Union.
The Lisbon Treaty also means that individual EU member states are not allowed to decide in certain areas if the EU already has done so. Those areas are: the internal market, social policy, agricultural and fishery, environment, consumer protection, transport, energy and some public health matters. The EU has exclusive decision authority in the customs union, competition rules of the customs union, monetary policy for the euro, conservation of marine biological resources (fishing), common commercial policy and international agreements.
They say that CETA has resulted in that 98 % of tariffs between EU member states and Canada are gone.
