Order Description

‘Subsidiarity and proportionality, as they apply to EU action, are failed doctrines. Neither does anything to prevent the pernicious, creeping competence of the EU.’
To what extent does this statement represent an accurate portrayal of the limits on EU law-making?
Note- The question asks about EU action, not that of its Member States. This is especially relevant when giving examples of case law(only cases regarding EU action). This area is only relevant where there is shared competence between EU and Member states. I also expect to see weighted arguments put forward by academics journals/articles. I would also like to know where these articles came from so I can go over them. A bibliography would be appreciated please.
