The ECHR was drafted as a set of high level rights. In the decades since that time the content of those rights have been developed by the court in all sorts of ways that people in signatory states have never had an opportunity to vote on. There is clearly a problem of legitimacy here - that’s being made explicit in much of the current criticism. I repeat, you can’t scold people out of their unhappiness at this situation. Contentious political problems need to be resolved by democratic, political processes, not judicial decision.
This, with all due respect, is gibberish in constitutional terms, @TullyApplebottom. All our laws are being developed by the courts all the time, we don't expressly take them back to be ratified by the electorate at every election. Yet no-one would claim that, for instance, that means we can ignore the Theft Act.
The reality is that the electorates in signatory states get to vote at every election. If they or the candidates think that some aspect of the way the Human Rights Court is carrying out its duties, or the way the Theft Act is being applied, is wrong, they then can draw it to the attention of the electorate, put it into a manifesto, and invite them to take it into account when voting. If they don't, the perfectly sensible assumption is that the electorate is happy with it.
