A family claims that a customary practice means a girl must marry whom the family chooses.
Some traditional practices involved symbolic capture preceding a negotiated marriage, with the woman's eventual knowledge and often tacit agreement.

This misapplication confuses a cultural practice with permission for abduction and forced marriage. Even in its original form, any practice must respect the fundamental principle of free and full consent to marriage.
