Talk about being two faced and double tongued!!!!
First it says that data correction and deletion can be granted (no doubt the clause they will repeat to anyone who asks about this), then the next two sections explain why this shouldn't be done!
63.a. "A data subject's right to the protection of personal and sensitive personal data and to the correction or deletion of personal and sensitive personal data is to be granted according to the practice of JW's as set forth in this policy".
63.c. "If a data subject requests access to, correction of, or deletion of personal data or sensitive personal data about himself, the organisation will fairly consider granting the request by balancing the interests of the individual [...] against the legitimate religious interests of the organisation [...]"
63.d. "The organisation has an interest in permanently retaining data regarding an individuals status as one of Jehovah's Witnesses. Deleting such information would unduly infringe on the organisations religious beliefs and practices."
