You can't cost benefit a precedent with the potential for extreme ramifications during future events. It's similar when you're making literally any regulation. You have to understand that yes, your decision and it's interpretation can cause undue problems for the parties being regulated.... but if you, via legal precedent, give up your power to effectively handle an even worse situation that could occur as a result of your lack of power to combat it.... then you really have a problem. You're going back to the courts to have them overturn precedent, and you're trying to do it based on Data which we know can be misinterpreted, misrepresented, etc...
