That is interesting because for those against the monarchy, it may give grounds and a forum in which to challenge the monarchy on legal grounds - i.e. the monarchy is against human rights. The Belfast Telegraph reported:
"The Human Rights Act puts the matter beyond doubt", he added and previous interpretations had been 'overcautious'... "National laws had to be interpreted in a way compatible with the human right to marry."
On a side note the Queen has decided to wash her hands of the whole marriage and not attend the wedding, maybe that is a cynical explanation but it must be pretty hard for Charles to have your mother skip your wedding.
The Queen is of course understands the historic codes, and follows them to the letter, which of course from one perspective are wrong but least she is playing by the set rules.
Charles, however, is the opposite, he is either modernising the monarchy or changing the rules as he goes along, the choice is yours
