Whatever. It doesn't matter.
The basis upon which the Supreme Court will rule in his favor as necessary might be of some scholarly interest, but that they're going to is already a given.
I think it's more likely that he'll order killings the same way that his hero Putin does - it won't be officially acknowledged in any way, but it will be an open secret that he ordered them. And anyone who tries to look into any of them any further will be silenced.
This is sort of unfortunate, but as long as the fediverse remains genuinely decentralized, I expect it's just going to be a fact of life. Instances are going to come and go, alternately riding in on waves of determination and enthusiasm and out in sluggish streams of burnout and ennui.
And in a way, I think it's arguably even a good thing, or at least not a bad one. The basic structure of the fediverse prevents centralization through ownership, but there's still a risk of individual instances gaining enough clout to effectively act as a centralizing force. Not that Lemm.ee was in that position or even headed that way, but still, broadly I think that the understanding that instances are likely ephemeral — that they come and they go, and much more to the point that that's as it should be — is an important one.
And it neatly illustrates a large part of the reason that I have at least a dozen or so accounts scattered around the fediverse, including, for a little while longer, this one.
