We have submitted a “two-part” session/”back to back” session? Does the one appearance rule apply here considering this really is the same panel but schedule in two parts?

The AAS considers two-part/back to back panels to be two separate panels.  The acceptance of both proposed panels essentially takes a slot from another panel that for example, may not have been accepted due to space constraints.  Therefore in the effort of fairness, “two-part” or “back to back” panels cannot contain the same individuals from the related panel.
