I mean, he's the chief of the Demon Border Patrol, he has to have some kind of authority that enables him to go over the heads of even the three elders under special circumstances. Henri has never been shown to invoke such authority before because he's never even really had to. This is the moment to show that being chief actually means something, given that the situation only happened because Narnia and Henri are the same rank, meaning Narnia needs fewer permissions to act. I imagine there are consequences to this choice of action, however.
Usually in stories for this type of out-of-jail situation, the author set it up by having a similar situation that can make the readers infere on a particular Character's capabilities.
For example during the ball of "13th of betrayal" (
chapter 301) we could have had the panic, with some characters assessing the situation, but Henry giving the ultimate order of what to do. Informing that as a 13th crown and head of police his word have weight, even over some other 13th crown for specific situations.
Here it's a bit out of the blue and, to me, hurt the story.
Now we're guessing Henry's power in the society : can he do that all the time ? If it's only sometimes, why for this case ? Etc.
I will admit that for the whole Scala Arc I've been waiting for something to severly impede Iruma, because he's been able - as Narnia says - to accumulate a lot of power fast. And with Kirio out of the picture, Baal being still too much of a challenge ; the story need to present Iruma with opposition, so that he can grow for the next challenge.
Fang Patrol cracking down was perfect for a setback, with the addition of providing a rival, more world building showing that it's a DEMON society and not a human society.
The story hit some of it, but miss the bullseye.
