From the way DJB talks about IETF processes, it's quite clear to me though that he has little trust/belief in the IETF consensus process. I thought he said as much somewhere but can't find that right now. (It's particularly obvious in https://blog.cr.yp.to/20260405-votes.html)
Which is why I'm noting the alienation of "IETF believers", which I should maybe clarify I count myself as. The IETF is a lot of people doing a lot of good work. It does include a bunch of questionable actors, anything from ignorant, incompetent, ulterior motives, to outright malicious. But all in all it has brought us the internet as it exists today and I can't help feeling a little, well, alienated by DJB's writs.

Anyway, IETF hasn't attempted to issue such a rule. On the contrary, IETF claims that WG decisions are not taken by voting: "Decisions within WGs, as with the broader IETF, are taken by 'rough consensus' and not by voting." This begs the question of what IETF thinks "rough consensus" means. Letting chairs make arbitrary decisions is a violation of due process.
More to the point, IETF can't override the definition of "consensus" in the law. That definition requires general agreement. Adoption of this draft was controversial, and didn't reach general agreement.
DJB making legal-ish arguments (or the idea that the IETF could be sued over a definition of "rough consensus") is absolutely inane to me. The choice of words of the IETF in defining its own processes for itself is not a legal one. And apart from that, which country's laws would that be? (I'm also quite skeptical about such a definition existing in a relevant manner to begin with.)
He famously doesn't support the IETF. In the long-long-long ago, back when I had a "home page" with my username and a tilde in it, I used to have a quote from him on it about the IETF and "ego standards". He's been picking fights like this with different IETF working groups for basically his entire career. This isn't even the first time he's picked a huge fight with IETF cryptography groups; he managed to get Kenny Paterson to publicly take him to task on the CFRG a few years back.
I, too, don't support the IETF (hence the quote on the web page, which I can't find now). But I happen to know enough about the people involved in this particular drama that I can see through his arguments here, and whether he realizes it or not, he's operating in supremely bad faith this time.
He makes the legal argument in more detail in https://blog.cr.yp.to/20251004-weakened.html#standards
The gist of it is that standards organizations like the IETF depend on a specific carve-out in US antitrust law (in order for it to be legal for American companies like Cisco and Google to participate in them), and that carve-out includes a specific definition of what "standards organizations" and "consensus" are. So even if the IETF uses different words to describe its processes, those processes still have to comply with the legal definition that separates a "standards organization" from, like, an illegal cartel.
