What would be considered as such in the Byzantine canons?
In the west there is a consideration of factors that would eliminate consent or voluntariness. But what of broader psychological impediments to contracting marriage, i.e. moral or spiritual impediments?
And deception is not the same as the lack of good judgment on the part of the person who doesn't really know the other person.
Is lack of moral maturity (which is different from emotional maturity but may include it?) sufficient to nullify the marriage? If one of the parties is selfish or narcissistic and cannot make a real commitment despite a verbal willingness to state that intent, can that party truly marry? Or can the law only limit itself to cases in which one deliberately lies about making a permanent and stable commitment to be with the other person?
What of other personality disorders?
How would one prove that a party never had the properly intentionality with respect to marriage? The mere fact that the party left the marriage? But someone could just change his mind and break his vow. It seems to me that it is psychologically possible for someone to merely mouth the vow without intending it; saying the words in order to attain some goal other than a true marriage. Would that be a conscious lie? Perhaps.
And what if the parties are psychologically or morally unable to fulfill the roles in marriage; i.e. the male is unable to lead and care for the other, or the female is unable to follow/obey and care for the other?
