I disagree, I think we should presume it wasn't used. In her surrender demands, Honor did mention the Parthian Shot and if there had been systems where the option had been employed, she would have brought them up. The RMN would have known, since the Parthian Option was specifically to be used to avoid confrontation with the RMN. No RMN, no Parthian. Also, Buccaneer had only a handful of targets in the first list, one of them bumped so that Hajdu's force could divert to Hypatia.
(And merging the two discussions...)
Honor did mention that the Parthian Shot was effectively an Eridani Edict Violation. If not in the letter of the Edict, then in the spirit. Belligerents are supposed to do their damned best to avoid civilian casualties, so firing without controlling your missiles is a violation of the spirit. Deliberately attacking civilian infrastructure must be even in the letter.
The Yawata Strike was a side-effect of the attack. But the MA simply paid no mind to the effect of attacking 100-km long structures orbiting inhabited planets. So it might be a violation of the spirit too. This will all depend on who wins in the end, since history is written by the victors. If the Alliance catches the perpetrators, they will be tried for EEV.
I only see them escaping that punishment if they pull an Albrecht, whether with nukes or with nanobots, or get killed in action.
I also don't think Parthian Shot was used- it was a tactic to wreck a system's orbital infrastructure if there were defenses, especially Manticoran ships, present that the SLN BCs didn't feel they could decisively win. At that point the run away and fire all the missiles they can back over their shoulder are the system infrastructure.
They didn't need Parthian Shot if there were no (effective) defenses. They could wreck the infrastructure far more efficiently with energy weapons, wedges, or even carefully targeted contact nukes. Not by wasting tons of missile on extremely long range, low probability, shots.
IIRC it's orbitals that are primarily civilian residences that are protected by Edict. The facilities around Basilisk were mostly orbital warehouses, some support manufacturing, that kind of light industrial thing. I'm sure there was some on orbit housing for workers or transients; but there was no significant system population living there. That apparently made them fair game, despite not having any direct military uses.
Oyster Bay hit stations that did have much, much, larger civilian residential presence. But they were also the system's naval shipyards, with plenty of in service warships docked; again making them fair play.
Hypatia (in addition to being a member of the League; not at war with them) has no apparent military presence at her stations; and while they undoubtedly had some light industrial capabilities they also (unlike Basilisk) had a significant orbital population. I'm not sure exactly what combination of items pushed that over the line into Edict violation - it might have been less egregious if a declared state of war existed - on the other hand it might not have; since it still had no appreciable military significance.
