Article 9
Section 4

(C) Exception. The legislature by act may direct the appropriate parish authority in Terrebonne Parish to transfer title and ownership as to certain lands near Bayou Dularge in Section 16 of Township 20 South, Range 16 East, which due to an error in the original governmental survey completed around 1838 until recently were thought to be within Section 9, to those persons who have possessed the property under good faith and just title for a minimum of ten years or to those who have acquired from them, reserving the mineral rights as just and sole compensation for the transfer. Consistent with the provisions of Article XIII, Section 3, the notice requirements of Article III, Section 13 are satisfied for an act passed as a companion to the act setting forth this Paragraph.
