The state or any town interested in the support of a child born to parents not married to each other may, if the parent who gave birth neglects to bring a petition, institute such proceedings against the alleged parent, and may take up and pursue any petition commenced by the parent who gave birth for the maintenance of the child, if the parent who gave birth fails to prosecute to final judgment. The petition may be made by the Commissioner of Social Services on information or belief. The parent who gave birth to the child may be subpoenaed for testimony on the hearing of the petition.
