Every welfare authority shall from time to time make inquiry whether there are any persons residing within their area who undertake the nursing and maintenance of foster children.
If a person who undertakes the nursing and maintenance of a foster child refuses to allow any such visitor or other person to visit or examine the child or the premises in which the child is kept, he shall be guilty of an offence.
If any such visitor or other person is refused admission to any premises in contravention of this Part of this Act, or has reason to believe that a child under the age of nine years is being kept in any premises in contravention of this Part of this Act, he may apply to a justice of the peace, and the justice, if satisfied on sworn information in writing that admission has been so refused, or that there is reasonable ground for behaving that an offence under this Part of this Act has been committed, may grant a warrant authorising the visitor or other person to enter the premises for the purpose of ascertaining whether any such offence as aforesaid has been committed, and, if any person obstructs any visitor or other person acting in pursuance of such a warrant, he shall be guilty of an offence.
