Is it valid for a virgin woman who has no father or brothers to marry, where her paternal uncle on her father's side (her amm, her father's younger brother) marries her off, even though her paternal uncle on her father's side (her amm, her father's older brother) is present?

If a woman has no father or brothers, and her younger paternal uncle marries her off, then her marriage is valid, even if her elder paternal uncle is present, provided that the younger paternal uncle is an adult, of sound mind, just, and marries her to a suitable match with her consent. Giving precedence to the older among the guardians is only recommended.
