Nonsensical and terrible? Maybe. But, consider this: if one person (could be the petitioner) lacked discernment of what it meant to make a lifelong commitment at the point of the marriage ceremony, that can be grounds for the issuance of a decree of nullity. In this way, the petitioner has the opportunity to influence the outcome by recognizing the inability to hold true to a lifelong commitment, implying he or she couldn’t discern what that meant when they got married. Debatably, the fact they’re divorced proves this lack of discernment to become self-fulfilling and true, in retrospect.
