In which case the SC held that unwed mother can be the sole guardian of a child ?

ABC v State (NCT of Delhi) recognised that an unwed mother could pursue sole guardianship without being compelled to notify an uninvolved putative father. The Court treated the child's welfare as paramount and also considered the mother's privacy. It directed the guardianship court to consider her application on its merits without requiring that notice, rather than granting every unwed mother guardianship automatically.
