The grounds for annulments have been so broadened since 1962 that virtually anyone who applies for one will be granted it. Taking nothing away from those whose marriages were TRULY invalid, but an annulment today is barely more than a Catholic divorce because the Church has allowed the argument that the breakdown of the marriage after the vows were exchanged to be redefined as a condition that existed before the marriage took place, thus satisfying the requirement that states that an impediment must exist at the time the marriage takes place for the marriage to be deemed invalid. By today's standards, practically anything that goes wrong in a marriage at any time can be defined as a condition that existed but was unknown at the time the marriage took place. Many Catholics, in their desire to separate from their (perhaps) abusive and/or unhealthy marriages, have bought and continue to buy into this false argument.
This is yet another result of yet another case of extreme recklessness on the part of the Bishops, who were more concerned with maintaining a declining congregation than accounting for the unintended consequences that would come and have come a thousandfold as a result of their shortsightedness. Now, while they're STILL trying to maintain the same declining congregation that they were trying to maintain 50 years ago, they're trying to undo the un-reversible damage that has been done due to their previous decisions.
