Censorship of an onchain dapp - as per the example in the article.
But how exactly they would convince ECAF that censorship must happen?
There must be a dispute over an article of the constitution. Which article that could be? And how it is broken by a dapp so that somebody can demand it to be censored? ECAF doesn't have any jurisdiction on things outside the constitution, so it can't give any rulings on them.
If ECAF/EMAC are named as the sole arbitrator on the protocol layer then they provide the access for states to make these kinds of requests.
How would they convince ECAF/EMAC to act? Threats probably.
No matter how many threats they make against ECAF it doesn't have any effect. If the case is not a dispute over certain articles in the constitution, ECAF can't do anything about it. ECAF simply doesn't have the authority to make those rulings.
If ECAF makes a ruling that's clearly outside of its jurisdiction, it will be immediately noticed and ECAF's indepencency will be seen as compromised. Until this has been dealt with, no rulings from ECAF will be taken seriously.
Protocol layer = the constitution. ECAF can't do anything about things outside of the constitution.
Please, write down the whole case like you think it would go. Then you can see it is practically impossible to happen in real life.
