The European Court of Human Rights (ECtHR) ruling in Hirst v United Kingdom (No.2) has generated much debate in the UK.

In questioning how and why the blanket ban remains in place, this article examines the wider Euro-scepticism. The author has also employed the British doctrine of parliamentary sovereignty to lay an ultimate challenge against the legitimacy of the whole Convention System in Europe.
