Some jws/ex-jws have sued the WTS regarding the validity of their baptism and previous baptism questions. This way the individual has to swear "allegiance" to the WTS as well. Note it is not until 1985 that the organization is mentioned in the questions.
There is significant cause for annulment. When I was baptized at the age of 16 I was not of legal age to make life’s most important decisions, including marriage, consumption of alcohol, voting and joining an army. Jesus himself was not baptized until the age of 30. Therefore I believe the Watchtower Society uses coercion of impressionable minors to build its ranks. I was misled into forming a contract with the Watchtower Society which binds me to the regulations of the Jehovah’s Witnesses Governing Body, under false pretences of it being “god’s spirit directed organization”. Until this year I believed the Watchtower publications to be truthful. The research I have done at the request of ... has resulted in me finding otherwise.
