Can you point me to an ML decision that was overturned on this forum? I only know of some clearly incorrect appeal decisions made by humans being overturned.
I do remember one instance early on where they did reevaluate ML rejections after tweaking it. I was affected, but had already resubmitted mine by then. If I can find a reference to that, I will edit it in here.
