Section 71. Special proceeding or habeas corpus to obtain visitation rights in respect to certain infant siblings

Where  circumstances  show  that
  conditions  exist  which equity would see fit to intervene, a brother or
  sister or, if he or she be a minor, a proper person on his or her behalf
  of a child, whether by half or whole blood, may  apply  to  the  supreme
  court  by commencing a special proceeding or for a writ of habeas corpus
  to have such child brought before such court, or may apply to the family
  court pursuant to subdivision (b) of section six  hundred  fifty-one  of
  the  family  court  act; and on the return thereof, the court, by order,
  after due notice to the parent or any other person or party  having  the
  care,  custody, and control of such child, to be given in such manner as
  the court shall prescribe, may make such directions as the best interest
  of the child may require, for visitation  rights  for  such  brother  or
  sister in respect to such child.
