> keep at it until they succeed

Is there any EU process to codify principles (e.g. Human Digital Rights) that need to be upheld in future attempts?

The EU article #8 of human rights [1] is deliberately loosely defined, both sounding nice at the first glance, while allowing for Chat Control style surveillance.

    Article 8 – Right to respect for private and family life

    1. Everyone has the right to respect for his
    private and family life, his home and his
    correspondence.

    2. There shall be no interference by a public
    authority with the exercise of this right 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.
