Well, no. Switzerland is not an anarchic commune, it's a representational democracy, just one that makes heavy use of referendums. But just like elections, referendums don't establish consent, they establish majority support. "The population" isn't a cohesive entity, even less so than "the government". If the government is failing to take action and there is no sufficient majority to "force it", that's not "the population" doing it, that's just the majority of the population not intervening (and that doesn't even get into the difference between "the population" and "all eligible voters").
By definition, the ECHR court is the right place to take this if the government refuses to take action and there is no democratic majority for this. If you think the ECHR only exists for "rogue states" that flay their own population in public or turn ethnic minorities into lampshades, that should be a learning opportunity for you to read up on human rights and the ECHR specifically.
> If Switzerland is commiting a human rights violation by doing this, what monumental human rights violation is committed by India. A country which uses the oceans to distribute it's waste globally? How about China, burning endless coal?
This is literally a textbook example of whataboutism but the answer is yes, they're all bad and there are certainly worse offenders than Switzerland.
But unlike Switzerland, neither China nor India are signatories to the ECHR so they're irrelevant to this case.
