I actually agree with you, quatar. School policy should be followed, and sanctions consistently applied. That's one of the basic principles of positive assertive discipline. However, the OP asked what to do in a situation where he/she perceived that the policy hadn't been followed, for whatever reason, and I gave some advice that actually dealt with the situation rather than simply take positions on a barricade. I think the "debate" - if you can call it that - which has gone on is more focussed on the balance between rewards and sanctions.
