Well, not only are JWs expected to lie when giving parts at a Circuit Assembly™, they are also expected to lie when they testify in court on behalf of a JW who is being represented by a WTS lawyer.
When I was a child, our family was friendly with another JW family - their kids were the same ages as me and my siblings and we were in the same classes at school. Anyway fast forward several years, and their youngest child gets pregnant, DFd and then marries the guy she was with. Eventually she decides she wants to be Reinstated™ so she can have contact with her JW family members. Her mom starts sending the mags to the house, which makes the girl's husband furious - ooooh, Persecution™! - and they eventually divorce. His family is well-to-do and threatens to do whatever they can to get custody of the kids - more Persecution™!
Because this is apparently a 'landmark' case the WTS laywers get involved. The two (Publisher™) Sisters™ who have been Conducting™ a Bible Study™ with this girl are asked to testify on her behalf, along with the two Special Pioneers™ who know the family very well. The WTS lawyers spend a couple of weeks with the Congregation™, and Monday to Friday consisted of intense coaching sessions with the four Sisters™ where they were practicing different scenarios that might come up in the court room. One such scenario bothered one of the Publisher™ Sisters™ very much. The question from the bench was something along the lines of "Do Jehovah's Witnesses teach that the government and its agents are under the control of the Devil?" We ALL know that this is taught. It's documented in the literature, and it's easily proven that it's taught. The Sister™ was conflicted - she was expected to swear on the Bible to tell the truth, the whole truth and nothing but the truth, and she was being told that in order to get the win for the WTS, it would be necessary for her to lie under oath - to commit the crime of perjury and suffer the consequences - by a legal representative of the WTS.
To add insult to injury, the two Special Pioneer™ Sisters™ were allowed to count the time spent in these coaching sessions toward their required hours for Special Pioneering™, which amounted to 150 hours per month at the time, the two Publisher™ Sisters™, putting in the same amount of time in the coaching sessions, were forbidden to add those hours to their Field Service Report™. This was the reason I even heard about the rest of the case, because my mom was so annoyed that she wasn't allowed to put those hours on her Field Service Report™, when she had given up her other activities in order to participate in these coaching sessions. She was actually less peeved about being asked to lie on the witness stand because for all the coaching time she put in, she wasn't called to testify. In a way, it was like Abraham's hand being held back from sacrificing Isaac - he was willing to commit the act in his heart, and then wasn't required to carry it through to completion.
