This is a diversity action for damages brought against R. J. Reynolds Tobacco Co. in which it was alleged that the decedent, Hudson, contracted cancer of the larynx and lungs as a result of smoking Defendant’s cigarettes.1 Recognizing Lartigue v. R. J. Reynolds Tobacco Co., 5 Cir., 1963, 317 F.2d 19, cert. denied, 375 U.S. 865, 84 S.Ct. 137, 11 L.Ed.2d 92, as an Erie lion in the street, the Plaintiff’s counsel to secure below and here a definitive ruling on controlling legal issues acquiesced in the ingenious procedural device of answers to interrogatories as a means of restricting the claims to very specific contentions which thereby excluded all others. Those claims negatived scientific foreseeability, peculiar defects in the cigarettes, and cancer consequences to a substantial segment of the public.2
*542After remand following an earlier appeal on limitations3 Defendant again moved for summary judgment on the ground that an implied warranty under Louisiana law covers only knowable, foreseeable risks. On the basis of Lartigue and Green v. American Tobacco Co., 5 Cir., 1969, 409 F.2d 1166 (en banc), the Trial Court granted Defendant's motion.
On appeal, Plaintiffs contend that the Trial Court erred in relying on Lartigue because it was erroneously decided, and erred in relying on Green because it is not controlling.
Wholly without regard to Green which is a Florida case, we affirm on the basis of Lartigue. Lartigue presented exactly the questions presented by Plaintiff in this case and Plaintiff does not contend otherwise. We are bound by the Lartigue determination on this issue (see Manning v. M/V “Sea Road”, 5 Cir., 1969, 417 F.2d 603, 610-611, note 10) until, if ever, the Court en banc re-decides the question or the Louisiana courts hold differently.
Affirmed.
. By suggestion of death the Court was advised that Appellant Elbert Berry Hudson died on February 18, 1970 in Bogalusa, Louisiana. Thereafter upon motion and notice the Court ordered substitution of the parties, F.R.Civ.P. 25(a) ; F.R.A.P. 43(a), as follows:
Ella Mae Nolan Windham, the first wife of Hudson. (His second wife predeceased him.)
Elbert Berry Hudson, Jr., Hudson’s son by his first marriage.

Patricia A. Hudson Carroll, Hudson’s daughter by his second marriage.
Margaret Jacqueline Hudson Davis, Hudson’s daughter by his second marriage.
James B. Hudson, Hudson’s son by his second marriage.
. By formal answers the claims were precisely limited:
“(a) He does not contend, and does not intend to offer proof to show, that defendant could or should have known, through any developed human skill or *542foresight in existence or available at the time plaintiff contracted his cancer, that the smoking of its cigarettes could cause cancer of the larynx;
“(b) Plaintiff does not contend, and does not intend to offer proof to show, that defendant’s cigarettes and smoking tobacco were in any material respect different from or less safe than other brands of cigarettes and smoking tobacco nor that they contained any substance not ordinarily used in the manufacture of cigarettes and smoking tobacco generally nor any element which was not a natural and ordinary ingredient thereof;
“(c) Plaintiff does not contend, and does not intend to offer proof to show, that the smoking of defendant’s cigarettes and smoking tobacco, or of cigarettes and smoking tobacco generally, causes cancer of the larynx in any size-able or substantial segment of the smoking public;
“(d) Plaintiff’s sole contention at the trial will be that he smoked defendant’s cigarettes and smoking tobacco and that his cancer was caused thereby.”
