It's not too late for your KH to get legal advice from a local attorney to protect it's membership. I am sure some "poison pill" language can be written into the congregation bylaws that would make it nigh impossible for the WT Corp to close down your KH and absorb it's assets.
Eureka!! I know what to do!!
Your KH bylaws should require that a legally recognized member of the Faithful and Discreet Slave class must show up in person at a KH meeting to request a vote on the dissolution of your KH, and it must pass by a 2/3 vote , before the WT could close your hall.
Has anyone seen one of the F&DS lately?
