The district consumer forum in Kolkata rejected my complaint; how do I appeal?

An appeal against the District Consumer Disputes Redressal Forum in Kolkata lies to the State Consumer Disputes Redressal Commission under Section 51 of the Consumer Protection Act, 2019 within 45 days (extendable). Further appeal lies to the National Commission, and then to the Supreme Court; Calcutta High Court writ jurisdiction under Article 226 may be invoked for jurisdictional errors. The appeal should annex the impugned order, the complaint, and additional evidence if permitted. West Bengal Premises Tenancy Act 1997 must align with the central Act, and the State rules prescribe fees and procedure. The forum can order refund, replacement, compensation, and penalty for deficiency. The appeal must be filed with the prescribed fee. Mediation is encouraged under the 2019 Act.
