Extracting damages from the congregations surpluses
I realize that you believe you've come up with quite a clever loophole to the legality of DF'ing, but here is a question. Let's say someone does as you recommend, and writes a letter of withdrawal, secretly hiding it away. Then let's say sometime later, the local elders decide to DF the person, making the standard "no longer a JW" announcement.
How exactly do you think you are going to "extract damages?" What is the exact legal theory/ cause of action that you think would be successful? Just to run off a few that seem closest, Intentional infliction of emotional distress, slander, defamation, invasion of privacy, etc. The problem is none of them would be viable. Or is there one that I missed?
