EU probably not competent to sign international trade agreements on its own

The Europe I dream of

The legal dispute has arisen on the Singapur-EU treaty, a precursor of the CETA, TTIP, TISA and similar totalitarian treaties that aim to demolish the capability of sovereign institutions to regulate a lot of things. The contention is that, while the EU (Commission, Council and Parliament) has the "exclusive" power on trade issues, it does not have it on so many related issues (work conditions, environment, transportation, public contacting, etc.) that it seems legally impossible to sign such "trade treaties" without the individual approval of all member states (their governments and parliaments). 

The issue is right now at the EU's Court of Justice, as the Commission (the EU's executive branch, presided by tax-heaven native Adolf Whatshisname Nobody Junker) has been forced to request such an assessment, as more and more eyebrows were being raised. 

The stand of the Commission is that they do have the exclusive competency because it is all "trade", an exclusive EU competency, the rest being just shades of it. But it's quite apparently not the case. It is no minor matter because even the EU's Court of Justice has limited competences and state-level courts could perfectly decide that their own sovereign legal frame, including their interpretation of the EU treaties, is above EU's vertical totalitarianism on these matters. 

But worry not, Junker and his eurocrats won't resign no matter what. The EU will collapse and Hell will freeze before the Eurocrats surrender their power.
