I served on a BOE that had a controlling elder. His brother-in-law was a CO and he had friends back at the Vatican and was always calling the service desk to back him up if an issue arose in which he didn't get his way. All the other elders would give in to him so he got his way most of the time. One time he tried to interfere with a JC on which he didn't serve. I had served on that JC and we had been compassionate in our decision regarding a young couple that had got into trouble with JW rules. He complained that we had been too lenient in our decision and tried to overturn it for a harsh sentence. We stood firm and let the couple off lightly. He complained to the CO but still wasn't able to get his way.
The last two years I served as an elder our BOE became polarized with him as the reactionary and myself and two other elders as the liberals. The rest of the BOE tended to be moderates who could go either way. Later one of the liberal elders was forced off the BOE. However, after reading Crisis of Conscience, I realized the JW religion was hopeless and resigned from the BOE and faded away.
