Before ARNOLD and FAGG, Circuit Judges, and DUMBAULD*, Senior District Judge.
PER CURIAM.


1
In this action for strict liability in tort, plaintiff Patricia McElhaney claims to have sustained injuries as a result of her mother's taking the prescription drug diethylstilbestrol (DES) during her pregnancy in 1949.  The defendant Eli Lilly & Company conceded that it manufactured the particular DES taken by the plaintiff's mother.


2
Prior to trial, plaintiff indicated to the District Court that she would offer no proof that Eli Lilly knew or should have known of the dangerous condition of the drug.  Defendant likewise conceded that no warnings were given indicating potential dangers of the drug.  Based on these concessions and comments j and k of Sec. 402A of the Restatement (Second) of Torts, the District Court granted the defendant's motion for directed verdict.1


3
On appeal, McElhaney argues that the District Court erred in holding that the courts of South Dakota would apply comments k and j of Sec. 402A.  On questions of state law, we normally defer to the judgment of the District Court.  Hence the District Court's interpretation of South Dakota law was reasonable.   McElhaney v. Eli Lilly & Co., 575 F.Supp. 228, 230 (D.S.D.1983).


4
The South Dakota Supreme Court has adopted strict liability as expressed in Sec. 402A.   Engberg v. Ford Motor Co., 87 S.D. 196, 205, 205 N.W.2d 104, 109 (S.D.1973).  Further, comment k has been applied in a previous South Dakota case involving a prescription drug.    Yarrow v. Sterling Drug, Inc., 263 F.Supp. 159 (D.S.D.1967), affirmed, 408 F.2d 978 (8th Cir.1969).


5
Affirmed.
