It is possible that she put someone on there without their permission, but it seems unlikely, especially since all of these lawyers were onboard the train at the time. In my field, any papers we submit to the standard journals results in an email sent to all the authors at the time of submission, so we know immediately if someone has put our name on something. There are journals that are scummy, and even put editors on their board without their permission, but we all know those journals suck and avoid them (unfortunately foreigners from poorer nations get sucked in by them).
Is there anything like that in the legal fields? You’d think that a court would send out announcements about a case to everyone working the case.
