DO NOT GO!!!!!!!!!
The KS10 Elders handbook states that it must be spiritual fellowship with other DF's for them to be able to DF you.
There is a small chance they are bluffing. (Though they might try to use their new favorite Brazen Conduct or Causing Divisions card) They will need to get their witnesses to say exactly what has happened.
DO NOT GO!!!!!!!
IF... IF... IF... - they communicate afterwards with you that you have been disfellowshipped then tell them you do not recognise their authority; that they are breaking their own rules and you are appealing and are writing to Bethel and if any announcement about you is made then you will instruct your lawyer to seek legal remedy against the JC members individually.
So ...
1. SHUT UP and DON'T GO.
2. IF they hold a JC in absentia then they MUST tell you the result.
3. IF THEY DO ... Tell them you are ignoring their incorrectly convened "theocratic" court and you are appealing to Bethel and to a lawyer about seeking legal and financial redress if any announcement is to be made.
4. Keep us informed so we can help you every step of the way.
DO NOT GO!!!!!! UNDER ANY CIRCUMSTANCES!!!!!!!
