Legallity of releasing complaint letter to a resident

We have two neighbors locked in a long standing feud. One sends complaint letters to the board on a regular basis. Most, if not all, are completely baseless.
The second neighbor has finally had enough and wants to sue for harassment, and has requested copies of the letters the first party has sent to us complaining about him.
It's my contention that those are private correspondence and shouldn't be released unless subpoenaed in the eventuality of a lawsuit. That way we would remain neutral, and not divulge confidential information.
I don't want to take sides, and I don't want to break the law, so I come to you in hopes of receiving good advice. I realize this is a legal question, but thought I'd try here before spending money on an attorney.
Thank you in advance for any help you might offer.

Ahh, the old who is the complaining party question and is there a right to privacy. This has been asked before and honestly, it depends on your Associations enforcement policy.

My Association will respond to any written complaint and investigate the alleged infraction.
If the Association sees the infraction then, for us, the Association becomes the complaintant (similar to the police responding to a call, if they see something that is in violation of the law, then they are the witness to the criminal act). However, if the Association determines that their is not a violation at that time, they respond to the written complaint saying that the issue was investigated and no violation was found. The letter and the response is then filed in both lot files (the complainer and the alleged violator).

Each member is legally allowed to look at their file, and since the letters are filed in each lot file, the member would see them.

If your Association has a policy that each complaint of an alleged violation would be considered confidential, then you would need to follow your policy. However, considering that the Association is being caught in the middle, if your policy is silent I would suggest you get a legal opinion from your Association attorney.

We did investigate each complaint and sent the complaining party a well thought out response on each one.We are as tired of the complaints as is the party to whom the complaints are issued. No action was needed or taken in any of the complaints.

There is no harassment if no action was taken. I can send you a letter all day long about a member's grass being too tall but if the HOA doesn't take action then the member being complained about isn't be harassed. Plus it is NOT harassment if the HOA sends notification to correct an action.

It sounds like these two are trying to drag the HOA into their battle. Just don't let them. If they threaten to sue, then be it. Let them sue each other. Have their lawyers subpeona the documents from the HOA. Whatever happens just don't let them make the HOA their great divide/communicator.

Let them both know that the HOA is made up of EVERYBODY in the neighborhood. Which means that ALL members would also have access to the records as well if they want to play that game. You sue your HOA your suing yourself and your neighbors. Let that philosphy set in for a bit for them to chill out and back off the HOA. They need to put this into the police area and NOT the HOA to manage. Harassement is a legal issue NOT an HOA's.

I had a policy of reading correspondense we received at our open meeting. Let it be known if one writes a letter to the HOA that it will be read openly amongst all the members in attendance. It will still be a board decision what to do and how to respond. However, it will be known to everyone in attendance what is going on. Add a little embarassment to the mix. If they get into a fight then call the police.
