The responsibility for the maintenance of the 'lists' of independent trade unions falls to the certification officer. The certification officer is an official designated to oversee and ensure that trade unions operate within the regulations laid out in employment and labor laws, including the maintenance of recognized independent trade unions. This role is crucial for ensuring that trade unions are properly registered and compliant with relevant statutes.
