There you go then: economic resources aren't a catch all. Crude oil could have been used for clarity, but wasn't. Sorry, but it's ambiguous and any lawyer will be all over that.
The more important thing is that there's a whole detailed Article (6) explicitly setting out prohibitions on oil IMPORTS from Syria to the EU yet we are meant to believe that they left oil EXPORTS to Syria, a far more important topic given third parties could be impacted, to be caught by an ambiguous catch-all provision in Article 14? Unlikely.
Crude oil was clearly high in the mind of the draftsman writing it hence the creation of an entire Article dealing with that alone yet they only decided to deal with oil IMPORTS from Syria, not EXPORTS to Syria.
Would be nice to see the Gibraltan Supreme Court's opinion on this, but they must not be too confident in their reasoning if it was held in private.
