I hate to always be a buzzkill, but all of these cases are significantly factually different, relying on factors that would almost never occur in the JW org. The key with Guinn is that they publicly annonuced her "sins" from the pulpit and sent letters around to other congregations. They also sent their members to hound her to get her to "repent." If you want to have a balanced view of the state of the law, make sure you read Paul v. Watchtower also.
That said, here are some situations where I believe the law could *possibly* be "on your side" in the U.S.
- You are expelled without them following proper procedure. E.g., without a committe of 3 elders or for a stated reason that is not a disfellowshipping offense.
- Comments about the specific nature of your alleged offenses are announced from the platform, or other untrue specific information about you.
- Elders or other JW/WTS persons continue to attempt to contact you after you make clear you have no interest in being part of their organization.
- You are removed from an offical legal status without your consent, e.g. as a trustee or officer of the land ownership entity for your local congregation.
Other that that, write a letter to yourself if you wish. I suppose it's not going to cost you anything. I would not suggest that anyone line a lawyer's pockets trying to sue over run-of-the-mill disfellowshipping and shunning. But if you want to, it's your money. The legal can of worms that would be opened if courts ruled that people can't shun would be unbelievable. It's morally reprehensible that they emotionally blackmail members with the threat of shunning. Let's be realistic, it's awful if your family shuns you. Mine does. But even if you win in court, they will just view it as persecution. If your family is willing to listen to the WTS and shun you now, do you think they'll decide to associate with you even if you win a judgment in court? If you're out, you've already won to a large extent. Collect your chips and take them with you.
