Joan - I have to say I enjoy reading your posts. They are insightful and educational. And I do look forward to hearing more of your views in the future.
Keep in mind, that "lack of due discretion" has all the full force and effect of all the other reasons for granting an annulment.
To Jerry's question - there is a defender of the bond of marriage who is present in the proceedings, so any reasons that cannot establish a grounds for an annulment - I'm speculating here, Jerry - likely would eminate from that person.
The annulment process was very educational to me, mostly because I learned things in it that I never heard in years of Catholic grade school, high school and university educations. And I see people on here committing errors that would be grounds for an annulment and just pray that someone intervenes to point out the error before it's too late. To this end, I think the potential of CM in the Catholic church has yet to be fully tapped ...
Good, informative post, John. However, I am curious about the errors you see on CM which could lead to future grounds? An example or two would be helpful. I certainly do not want to be guilty of any such behavior.
