Sec.25. Enforcement of orders of the District Forum, the State Commission or the National Commission
(1) Where an interim order made under this Act, is not complied with the District Forum or the State Commission or the National Commission, as the case may be, may order the property of the person, not complying with such order to be attached.
(2) No attachment made under sub-section (1) shall remain in force for more than three months at the end of which, if the non-compliance continues, the property attached may be sold and out of the proceeds thereof, the District Forum or the State Commission or the National Commission may award such damages as it thinks fit to the complainant and shall pay the balance, if any, to the party entitled thereto.
(3) Where any amount is due from any person under an order made by a District Forum, State Commission or the National Commission, as the case may be, the person entitled to the amount may make an application to the District Forum, the State Commission or the National Commission, as the case may be, and such District Forum or the State Commission or the National Commission may issue a certificate for the said amount to the Collector of the district (by whatever name called) and the Collector shall proceed to recover the amount in the same manner as arrears of land revenue.
Sec.27. Penalties
(1) Where a trader or a person against whom a complaint is made or the complainant fails or omits to comply with any order made by the District Forum, the State Commission or the National Commission, as the case may be, such trader or person or complainant shall be punishable with imprisonment for a term which shall not be less than one month but which may extend to three years, or with fine which shall not be less than two thousands rupees but which may extend to ten thousand rupees, or with both:
Section 25 and 27 of the Act have been enacted for speedy enforcement of the orders of the District Forum, the State Commission or the National Commission, as the case may be. These sections are in the nature of execution proceedings of the orders made by the three Redressal Agencies. While Section 25 of the Act visualizes the enforcement of such orders by a civil process, as if they were a decree or order made by a Court of law, whereas, Section 27 of the Act confers a quasi-criminal sanction for their enforcement by way of punishment with imprisonment or imposition of monetary penalties.
