The instructor's behavior is an attempt at interpersonal justice.
Interpersonal justice can be understood as the degree an individual affected by a certain decision is treated with respect.
This is a branch of organizational justice, which refers to the employees' general perceptions of what is right within the organization.
In this case, the instructor could have treated the student as a cheater, ignored him/her or completely shut him/her out for his/her actions. Instead of acting this way, the instructor listened to the student's arguments and spoke kindly. This behavior is understood as interpersonal justice since the student, affected by his/her own decisions, is still treated with dignity and respect.
