Who oversaw the IDR? If an agreement was negotiated, but the board rep won't sign off on it, you may need to go back to whoever negotiated the proposed settlement and see what your options are. If the board rep refused to sign it, that may be something you can use as evidence in your arbitration hearing.
As you probably know, both sides present their arguments before an arbitrator, who makes a decision. From the ones I've seen, both sides agree in advance to comply with the arbitrator's decision. Usually, they'll split the costs of the arbitrator (which may also include travel time, meals and whatever else was required to hear the dispute) and the winner agrees to reimburse the loser. There are certified arbitrators - you can try this website to look for one in your area https://www.adr.org/Arbitration
Attorneys CAN be trained as arbitrators, but some arbitration organizations mediate disputes in certain areas like insurance or securities. Years ago, the BBB in my area had a volunteer arbitration program where they trained all manners of people to negotiate settlements between BBB members and customers. I don't know if the program is still available, but I remember the training was fairly intense (about six weeks).
From the way you write this post, you are hopping mad over the IDR result or lack thereof. Considering you tried to follow the CCRs and the board rep replied "so what?", I understand, but before you do anything else, you really need to sit down, calm yourself, and then decide what your end game will be and what you're willing to do to get there. Otherwise, you'll find yourself saying and/or doing something you'll regret. Remember, even with arbitration, the rest of the board may tell you to kick rocks, and then it'll be time to get down in court - more money, time, and drama. If you win, you will have something to show the court if a lawsuit is your only option (that might also include receivership because you can show you tried to cooperate and they'll have to explain themselves.)
But even with that, the remaining homeowners won't go away if you win everything - how will all of you get along going forward? If you haven't already seen an attorney, talk to him or her about your options and see what you can find out about costs, and your chances. Anyone can sue for anything, and you might win, but they might appeal and this will go on for years. Suing is easy, collecting a judgement, not so much.
