Miss. Code § 29-1-25
In cases where lands have passed from the ownership of individuals into that of the state by some mistake, oversight, or unintentional default, the land commissioner, with the approval of the governor and the attorney general, upon satisfactory proof shall, provided said lands are then held by the state, reconvey such lands to their original owners or to those claiming through the original owners upon payment of all taxes, damages, and costs accrued, on such equitable terms as may be agreed upon in each case by the owner and the land commissioner.
In cases where the owners of land have, through mistake, permitted the same to be sold for taxes, and afterwards, to protect their titles, have repurchased from the land commissioner at the price fixed by law the land so forfeited, the state shall, upon satisfactory proof of said facts with the written approval of the governor and the attorney general, refund said purchase money less the amount of taxes, costs, and damages; and the land commissioner shall make a report of such facts to the next session of the legislature and ask an appropriation therefor.
