Complaint admission procedure sets referral, testing requirements, timelines, and powers for consumer commissions to proceed expeditiously. The District Commission, on admission, proceeds with complaints and must serve the opposite party to elicit a response. For goods alleging defects, it may obtain a sealed sample from the complainant, direct an appropriate laboratory to test and report within a prescribed period, require deposit and remit fees for testing, circulate the laboratory report, receive written objections, and afford parties a hearing before issuing orders. Where goods-procedure cannot apply or complaints concern services, the Commission directs the opposite party to file its version, decides on evidence or ex parte if necessary, may order electronic service providers to produce records, and may pass interim orders.
