How can I challenge the BTR mistake in Kerala High Court?

My application to the Taluk officer to rectify a mistake in the Basic Tax Register (BTR) (wherein the garden land in one survey number was split into two survey numbers by the Surveyors and one part was marked as Paddy land in the BTR in 1995, against the Kerala Land Tax Act and Supreme Court order, causing me massive financial loss) was rejected by reporting that the my land is at the same level as the predominantly Paddy land on the other side of the canal which forms the boundary of my garden land. Whereas the Paddy land is approximately 0.7 -1.5 meters deeper than my land, which remains as garden land in the Settlement register and title deeds as well as land tax receipts till 1995. District Collector has relied on this report and rejected my appeal to rectify the mistake in BTR, in Kerala, eventually leading to a court case in Kerala High court.
