That's a declaration, which is not binding. The ECHR art. 8 has similar contents and is binding. However, it has a 'unless we really want to'-portion:

"except such as is in accordance with the law and is necessary in a democratic society in the interests of national security, public safety or the economic well-being of the country, for the prevention of disorder or crime, for the protection of health or morals, or for the protection of the rights and freedoms of others."

Currently 'the West' happens to be doing its best to quash international law, so I'd expect even that thin veneer to crumble rather soon.
