Yes, like I said in the original post, it is not clear what the trigger was. Possibly a complaint of MOC if the "mental cruelty" suffered by her sponsor is true (as the IRB relied on). Or the VO (if she sponsored her 2nd husband) may have taken upon themselves to initiate it. After all, it is their job to ensure the integrity of the Act is maintained. Maybe if this case goes to the IAD more details will be released.
I'll reserve my sympathy for this person because a much more underhanded situation could also be true. A lot of money could have changed hands for all of this to take place as well as some long term planning. There is no indication that either a sympathy-deserving or scorn-deserving situation took place. LOL - obviously I've become jaded through what I've seen over the years. I used to be a much more sympathetic person! However, given the length of the timeframe involved, the opportunity this person and her counsel would have had to prepare for the hearing, and her statements, I'm inclined to believe something shady went down. The IRB has shown itself to be very sympathetic to H&C considerations but only when consistent, not at the 11th hour. A person always remembers the truth. Lies are much harder to keep straight.
Bottom line - IMHO it's GOOD to see consequences being doled out for MOCs. They make the task of sponsoring a spouse in a genuine couple that much more difficult and lengthy.
