Long term capital gains on immovable property

This discussion explores the calculation of long-term capital gains tax when selling land purchased in 1963-64, where the original construction was demolished before the sale. The core question is whether the capital gains tax should be based solely on the land's cost as of April 1st, 2001, or include the cost of the demolished construction as well. There's a concern that tax authorities might only consider the land cost due to stamp duty being paid on the land alone.
