“ Appellant is a sublessee of lands leased by the state of Louisiana in 1924 to the Terre aux Boeufs Drainage District. The lands had become the property of the state by an adjudication for unpaid taxes of 1911 to 1923. The lease by the state contained a clause that the lease woule end in case the lands were redeemed by the former owner or sold by the state. At the time the lease and sublease were made, the lands could be redeemed only by payment of all taxes, penalties, and interest due at the date of redemption. ”

“ Appellant then sought mandamus to compel the cancellation of the certificates, upon the ground that the Act of 1934 violated the Constitution of the United States (article 1, § 10, cl. 1; Amend. 14) in that the act impaired the obligation of appellant's contract of lease, deprived appellant of its property without due process of law, and denied to appellant the equal protection of the laws. Judgment against the appellant was affirmed by the Supreme Court of the state. ”

“ The questions sought to be raised under the due process and equal protection clauses of the Fourteenth Amendment are without merit. Bachtel v. Wilson, 204 U.S. 36, 41, 27 S.Ct. 243, 51 L.Ed. 357; Rast v. ”
