No I'm not. I was just listing some *general* concerns with emailed orders, having nothing directly to do with the case in question. I certainly did not say that orders received via email were not valid.
Heck in some situations orders were given over the commercial radio during WW-II. Something like "all soldiers return to your barracks, all sailors return to your ships". I think there may have been such announcements canceling leaves within the CONUS at the beginning of WW-II. Those orders had the same sorts of issues as emailed orders. My grandparents did not have electricity, if my Uncle had been on leave, he very well might not have heard the order to return to his ship/post for days. The attack on Pearl harbor occurred some hours after they would have returned from church. (Although to be completely truthful, I seem to recall my mother saying that they heard of the attack on their battery powered radio, but not everyone had one of those either, and they had to be used sparingly, as those old tube sets went through the batteries pretty quickly.).
But to repeat, none of that relates to this case, because the filing specifies that she got the orders.
