2. The parties' assertion

A. Where the designation of the land designated as the land transaction permission zone is cancelled, the Plaintiffs no longer need to obtain the land transaction permission even if the land transaction contract was concluded without obtaining the land transaction permission during the designated period of the land transaction permission zone. As such, the designation of the instant forest land as the permission zone was cancelled, and the instant sales contract became effective definitely, and the Plaintiffs are on the date of the contract.
