Adickes v. S. H. Kress & Co., 398 U.S. 144 (1970), was a United States Supreme Court case where the majority ruling, written by Justice Harlan, asserted that the burden of showing a lack of factual controversy rests upon the party asserting the summary judgment. It was later challenged by Celotex Corp. v. Catrett (1986), but the case was not officially overruled.
