I am not an attorney, but it sounds to me like the principal is aware that he has overstepped the line and his objective is to get you to sign something for readmission, which would absolve him of wrongdoing. He would like you to avoid seeking legal advice.
My view is that you hold all the cards but make sure that your son is telling you everything that happened in his exchanges with the middle school principal. Teens have the capacity to say and do things that later come back to bite us!
First, I would meet with the principal with a witness and record the meeting, if acceptable. Being firm but courteous and respectful, I would clearly state that I am there to inform him in writing of your position on the matter, which has been shared with the School Board via electronic submission within a few minutes of the meeting beginning. I would clearly state that the meeting is being held without prejudice to any of your son's rights:
- My son was acting in our family's interest to clear weeds from public property adjacent to my property with a weed hacking tool for long weeds (not a machete). As these weeds contribute to the pollen count, his actions also were in the public interest.
- My son was not working in close proximity to the middle school and his actions did not constitute a threat to anyone there.
- The middle school principal had no right to interfere in his activities or call him over.
- Further, records at the police department will confirm that officers told all concerned parties that my son was not guilty of any wrongdoing at the time.
- My son denies any wrongdoing in the events that took place, which are in any case not relevant to your son's relationship to the school.
- My son has been denied due process, including a failure to make available to him the documents related to the suspension, an exact account of what he is supposed to have done that merits disciplinary action, or worse, suspension, or a chance to present his account of relevant events.
- The foregoing constitutes a serious violation of his rights.
- My son has suffered material damages, which include in part denial of access to education.
- He fully reserves his right to seek redress against the high school, the middle school, and both principals in their private capacities, as their actions clearly constitute abuse of their powers as school principals.
- He is willing to consider foregoing the pursuit of any and all legal avenues open to him provided that certain demands were met.
These demands would include:
- Immediate reinstatement, and within 24 hours,
- A written apology from the principal on behalf of the school and in his personal capacity. The written apology should:
- Briefly summarize the events of the day and clearly state that my son had done nothing wrong and certainly nothing to merit disciplinary action by the school,
- Make clear that the matter would be set straight in his school records, which would permanently include the note of apology,
- Set out arrangements for special tuition to help my son catch up on all work missed,
- Outline arrangements for the broadcasting of a notice within the school so that all teachers and students were clear that he had done nothing meriting disciplinary action, in a way that would not cause undue embarrassment to school officials, and
- Provide an undertaking that neither they nor anyone else would disadvantage my son in the future.
Second, if he would fail to agree with any of the demands.
- I would restate his position clearly, so that we are both clear what he has said.
- Then, taking care to avoid any suggestion of extortion, I would mention that you realize that he may wish to change his mind after consulting with the School Board and repeat that he has 24 hours to meet your demands,
- Respectfully and calmly close the meeting, providing him with a copy of a pre-written letter noting that the meeting took place and that he is not willing to meet your demands.
- Notify him that a copy of the "failure to reach agreement" letter would be
- Sent to the School Board immediately and, if your demands were not met,
- You would be sharing both letters and additional materials with named TV stations and newspapers, with the goal of protecting other children from the abuse of their rights.
I had a similar situation unfold in California in the past concerning my children. I gave the gentleman involved 24 hours to unfold a series of events that were dramatically unfair and demonstrated such arrogant disregard for my rights. It was amazing how fast things got sorted out following this approach.
