This is determined when initially setting up the View/Email options on the Infraction. This is considered a default setting and when the infractions are assigned to students, it bases those settings on the View/Email settings on the infraction at that time. Each individual infraction can be updated for that specific infraction, but changing the settings on the infraction in Conduct settings will not change what is set on each student's infraction.
