So long as objections don't revolve around 'burn the cops' they're fine. Well, the DD 93 thing is ironclad, we're not sure if you definitely still have to get commander's permission to marry. DD forms are governments docs, noow, could she say 'well, the military didn't recognize it as a marriage so I didn't think I should list it as one?', sure, a little bit of BS in that but a good defense and assuming they wanted to perfect grounds to dismiss, but doesn't vice-versa mean not grounds to report it.

Now, the military discharging her? No choice, if someone brings you reasonable evidence of a crime in the military you have to act on it, as a commander. Otherwise it's dereliction of duty, we've got that so commanders can't use the twiddling thumbs excuse to overlook war crimes or plundering or rape etc. "Well, I know I've got this here written report from Pvt Snuffy saying X stole from the locals but I didn't think it my place to act on it and couldn't be sure it was proof' doesn't work, you can go to jail for that. You have to open an investigation or push it up the ladder, over to CID, etc. Your only defense otherwise is to say 'I didn't think it was reasonable evidence' and a marriage license is pretty solid proof of being gay, I don't think you can get any solider. If the people contacted hadn't opened an investigation or reported to someone who then did so, anyone who wanted to could have seen them hit with a horde of charges. You can get away with 'well, bob said he saw John and Ted kissing but he could hardly prove that and he might not have seen clearly' So whoevers desk it landed on probably wasn't the only person aware of it, or maybe they could have safely crumpled it up quietly and pretend they didn't ever see it, but with others knowing, it's gonna happen, and your asking someone to throw their career away and maybe even suffer punishment if they chose to sit on it. Hard to say how that would go down, I'd bet they'd go easy on someone for that too but it's asking someone a lot to gamble their career on it, that's even assuming many of the people involved aren't anti-gay or anti-gay marriage and might have been cheerful to proceed.
