The mechanism of rights makes a lot of sense in a constitution, to establish that these core principles of the legal code of Latveria and may never be trampled upon by subsequent laws, and then refer back to that as a judgement when evolving the law.

However, in recent years it's taken a life on its own and people all over the political spectrum are inventing new rights or denying established rights. At face value it seems like a punchy statement that this is a human right or that isn't a civil liberty, but there's usually nothing to back that up. It's nothing more than a vapid slogan used this way.
