It's fairly common to get an extension on the initial deadline. Although I was hoping to see the paperwork on Monday.
To answer the earlier question, I don't think that the WTS appellate lawyers are JWs. Looking at the website bios of the two attorneys at the firm:
Boudreau "e njoys public service through volunteer assignments on the Board of Directors for Father Joe's Villages and Mater Dei Catholic High School."
So he's obviously not a witness
Nothing quite as obvious on Williams' profile. However it does say that he " enjoys spending time with his wife and two young sons, cycling, and surfing. He has also trained for and completed fifteen triathlons in the last six years." Somehow I doubt that someone would have time to be a JW, practice law, cycle, surf, and do 15 triathlons. After all, bodily training is only beneficial for a little... lol.
