Unjust  There is an argument to be made that this form of punishment of parents is simply unjust. The legal basis of punishment is based on the principle that a sane individual is fully responsible for his or her actions. One can always point to dysfunctional families or other influences that may have had an effect on an individual’s actions, but the level of influence is impossible to quantify. Therefore, any level of punishment that is meted out to external sources cannot be matched proportionally to actions taken by these outside parties, thereby abrogating the principle of proportional punishment. As a result, any just system of punishment is bound by this constraint, and shifting responsibility to external sources is not consistent with our principles.  This argument functions best in the criminal justice context, but applies in the school context as well. Schools that adopt this policy must examine the ethical underpinnings of the policy, and if the policy itself is immoral, then regardless of its efficacy (which is disputed in the first argument and later on) the policy should not be adopted.
