LoL that's kind of funny. What were they going to do if someone objected based on non legal and non religious reasons?
The objections to which that question refers are, as far as I understand, of a legal nature. For example, "that man and that woman" cannot be legally wed because one of them is actually still married to someone else. In that case, a member of the congregation who was privy to that information would have a duty to disclose it in public at that particular moment.
Maybe the Anglican members in the forum can confirm if that is correct.
