Seems to me, after a quick persual, that the European Court of Human Rights is a tad overwhelmed with caseloads at the mo.
The member states must be shunting cases up at them at a fair rate of knots,some of our judges must be relishing getting their "out trays" emptied.
It is not the member states, but individuals who are overloading the court. In essence, it has become the final court of appeal, to which individuals are referring when they can't get an issue resolved in their own national courts. This is something which was not originally intended, and for which the court is not equipped. Therefore, the court recognises it must be trimmed back, and has been working to achieve that since 2009. But now, you get the British government claiming credit for something that was happening anyway.
