From the Telegraph UK:
Being tied to your mother's apron strings is sufficent grounds to annul a marriage by the Vatican, it has emerged.
Officials ruled on several cases of men and women who were judged to be so dependent on a parent that they were unfit for marriage.
Judges on the Roman Rota, the top Catholic tribunal in the Vatican, agreed for an undisclosed number of marriages to be annulled on such grounds, according to a review of the judicial year.
