There's a surprising number of variants on the initials ECHR amd EHCR, from courts to commissions. There's even one web site claiming that only the UK and French versions are genuine!

But our UK governments of both persuasions refused to implement it, until we eventually had to due to our EU membership since the EU had adopted it unchanged. It's good law, but often misused for partisan reasons as currently.
And the Tory party are dedicated to getting rid of it and replacing it with a limited Bill of Rights.
