This chapter shall not be construed to affect the validity of leases, contracts, or other instruments affecting tide or submerged lands, and there shall be no presumptions raised concerning the validity or invalidity of any lease, contract, or other instrument which is required by Section 6702 to be submitted to the State Lands Commission in order to make the provisions of Section 6701 applicable thereto because of the failure of the legislative grantee to submit such lease, contract, or other instrument to the commission, or because of any findings of such commission thereon.
