Under existing law, Russia is required to notify both the Secretary-Generals of the UN and the Council of Europe when it deviates from its obligations under international treaties by restricting the rights and freedoms of Russians. The requirement is in line with the European Convention on Human Rights.
Honestly, I had no idea that Russia was still even in the ECHR. I thought that when they’d left the Council of Europe in early 2022 that they’d also left the ECHR, but apparently not.

Okay, so they’d withdrawn from European Court of Human Rights jurisdiction later that year too.

Normally I associate the ECHR (European Convention on Human Rights) and the ECHR (European Court of Human Rights) pretty closely – my understanding is that the latter normally deals with decisions regarding the former – but apparently one can be in the former and still deny jurisdiction to the latter.
