JUDGMENT : 1. The petitioner entered into a sale agreement with the owner of a land. The sale agreement was not fructified. The petitioner approached the civil court. The civil court granted a decree of specific performance. Consequent to the passing of the decree, the document was executed through the court. There is difference between the consideration and the fair value of the land. Stamp duty paid was based on the consideration as shown in the sale agreement. The registering authority registered the document and proceeded against the petitioner under Section 45A of the Kerala Stamp Act, 1959 (hereinafter referred to as the “Act”). Noting that the petitioner had not paid stamp duty in accordance with the fair value, the petitioner was directed to pay deficit stamp duty by Exhibit P2 order. The petitioner appealed against that order before the District Collector. The District Collector affirmed that order. It is challenging that order, the petitioner approached this court. The short issue falls under a narrow compass with respect to the fair value fixed. The petitioner objects the fair value fixed in the appeal filed before the District Collector in terms of Sections 45A(4) and 45A(5) of the Act. 2. There are two modes of challenge in fixation of the fair value of the land; one is in terms of Section 28A of the Act, which has to be done in a time bound manner and; the other is an inbuilt mechanism as referred under Section 45A of the Act. It is to be noted that there may be a situation where at the time of notification under Section 28A, the person like the petitioner may not have the interest to object the fixation of the fair value of the land. The interest of such persons is protected in terms of Section 45A. This is so clear from Section 45A(5). It is referred that the Collector shall hear and dispose of the appeal in such a manner as prescribed under the Act and the Rules framed thereunder. It is to be noted that under Section 45A, in fact, particularly refers to the deficiency of stamp duty in comparison with the fair value of the land. Section 45A, therefore, deals with instruments not bearing stamp based on the fair value of the land. It is quite different from Section 45B. It is to be noted that under Section 45A, in fact, particularly refers to the deficiency of stamp duty in comparison with the fair value of the land. Section 45A, therefore, deals with instruments not bearing stamp based on the fair value of the land. It is quite different from Section 45B. Section 45B refers to the instrument undervalued by not showing the actual consideration. 3. Rule 7 of the Kerala Stamp (Fixation of Fair Value of Land) Rules, 1995 prescribes the procedures to file an appeal under Section 45A of Kerala Stamp Act. Rule 8 of the above Rule concerns the manner in which the appeal has to be considered by the Collector. Rule 8 spells that the Collector has every power to vary the fair value fixed. The cause of action to file an appeal under Section 45A(4) would arise only at the time of registration of an instrument. However, the cause of action to challenge the fair value under Section 28A would arise based on the publication of the fair value by the Revenue Divisional Officer. 4. The Government also framed rules for dealing with the matters coming under Section 45A of the Act. These Rules are called Kerala Stamp (Fixation of Minimum Value of Land for Registration of Instruments by Registering Officer) Appeal Rules, 1990. The said Rules provide the manner in which the Collector has to dispose of the appeal. It is to be noted that in terms of Rule 4 of the above Rules, the Collector has to conduct an enquiry. The enquiry is conducted to verify the correctness or legality or propriety of the decision in the matter. Therefore, the Collector has every power to review the fixation of fair value and modify it in an appeal filed under Section 45A(4) of the Act. If the fair value cannot be varied in terms of the appeal filed under Section 45A, there is no point in conferring such power with the District Collector. Therefore, apart from the powers under Section 28A, the Collector has also powers under Section 45A to vary the fair value fixed in respect of the land. But, this right can be availed only by such persons, who could not be considered as aggrieved at the time of the publication of the fixation of the fair value under Section 28A. Therefore, apart from the powers under Section 28A, the Collector has also powers under Section 45A to vary the fair value fixed in respect of the land. But, this right can be availed only by such persons, who could not be considered as aggrieved at the time of the publication of the fixation of the fair value under Section 28A. It is to be noted that an outer limit time is fixed for challenging such fixation of fair value in terms of Section 28A. 5. In view of the fact that the Collector had no occasion to advert to the fair value fixed in the matter, this court is of the view that the matter has to be remitted back to the Collector to reconsider the correctness of the fair value referred in the instrument. Accordingly, the impugned order is set aside. The matter is remitted back to the District Collector to reconsider the point whether the fair value fixed in respect of the land covered by the instrument is correct or not. Needful shall be done within three months after notice to the petitioner. The writ petition is disposed of as above.
