E-adjudication platform mandates electronic conduct of company adjudication proceedings, with postal or platform notices if contacts are absent. Rule 3A mandates exclusive electronic conduct of adjudication proceedings through a central e-adjudication platform, covering notices, filings, evidence, hearings, witness attendance, orders and penalty payments; pending proceedings remain governed by prior rules. If a party's e-mail address is unavailable, notices must be posted to the last known address and a copy preserved on the platform, and where no postal address exists, the notice shall be placed on the platform.
