SDCL § 17-3-5: Preservation of rights against validation of prior notices.

Any person deeming himself aggrieved by posting which was done prior to July 1, 1967, may bring an action to enforce his claimed rights on or before July 1, 1968. Nothing herein shall be construed to mean that the Legislature deems that such notice was insufficient but merely to give him a right to assert his rights by action provided he does so within the time herein limited.
