law: Children Act, 1960
  32. Presumption and determination of age
  (1) Where it appears
  
  to a competent authority that a person brought before it under any of the
  
  provisions of this Act (otherwise than for the purpose of giving evidence) is a
  
  child, the competent authority shall make due inquiry as to the age of that
  
  person and for that purpose shall take such evidence as may be necessary and shall
  
  record a finding whether the person is a child or not, stating his age as
  
  nearly as may be.
  (2) No order of a
  
  competent authority shall be deemed to have become invalid merely by any
  
  subsequent proof that the person in respect of whom the order has been made is
  
  not a child, and the age recorded by the competent authority to be the age of
  
  the person so brought before it shall, for the purposes of this Act, be deemed
  
  to be the true age of that person.
