SDCL § 5-5-23: State ownership of improvements not removed--Permit renewed by new lease by same lessee.

If such improvements are not removed in the manner and within the time specified in § 5-5-22 or within such further period as may be granted by the commissioner of school and public lands for good cause shown, or unless such improvements are disposed of as hereinafter provided, then such improvements shall become the property of the state without further consideration. In the event that any lessee, who, upon the expiration of his lease, re-leases such tract of land at the letting, any permit for improvements previously issued and his rights to the same shall be automatically renewed for the period of time covered by such new lease without any further action on the part of such lessee.
