When it comes to Congregation matters, it really does depend on who you are and how well connected your family is. In my Congregation, a well to do Elder's 18 year old daughter and her 19 year old fiancé were about to be DF'd for sleeping together. We were close friends with the family and knew that the daughter had done this with every boy she ever went out with yet never was disciplined by the congregation even though pretty much everyone knew about it.
This time they got the book thrown at them and the announcement of their disfellowshipment was to be made on the following Thursday. The family threw together a really fancy wedding at a country club the weekend before so that her JW Uncle Elder could give the talk and all their JW friends and relatives could attend. Talk about a farce and missing the point.
Whether it has been announced yet or not, the reason they were DF'd was because they were "wrongdoers" and supposedly a bad influence on the congregation. The announcement made no difference in their supposed "moral character". Everyone skirted around the this technicality and made a mockery of the whole purpose and intent of the practice of disfellowshipping .
P.S...these kids didn't last a year but had a child.
