				Description 
				o        
				
				
				On July 6, 1993, the right rear tire of a minivan driven by 
				Patrick Carmichael blew out.  
				o        
				
				
				In the accident that followed, one of the passengers died, and 
				others were severely injured.  
				
				Claimed Tire was defective 
				o        
				
				
				In October 1993, the Carmichaels brought this diversity suit 
				against the tire's maker and its distributor, whom we refer to 
				collectively as Kumho Tire, claiming that the tire was 
				defective.  
				
				Expert Testimony 
				o        
				
				
				The plaintiffs rested their case in significant part upon 
				deposition testimony provided by an expert in tire failure 
				analysis, Dennis Carlson, Jr., who intended to testify in 
				support of their conclusion. 
				
				Must have been a defect 
				o        
				
				
				Carlson concluded that the tire did not bear at least two of the 
				four overdeflection symptoms, nor was there any less obvious 
				cause of separation; and since neither overdeflection nor the 
				punctures caused the blowout, a defect must have done so. 
				
				District Court 
				o        
				
				
				Granted motion to exclude testimony. 
				o        
				
				
				Carlsons testimony was not subject to peer review, rate of 
				error and degree of acceptance within the relevant scientific 
				community. 
				
				Pl - Arg - Ask for reconsideration 
				o        
				
				
				Daubert should be applied flexibly. 
				o        
				
				
				Other factors could argue in favor of admissibility. 
				
				Court of Appeals - Reversed 
				o        
				
				
				De Novo review - anew. 
				o        
				
				
				Supreme Court in Daubert explicitly limited its holding to cover 
				only the 'scientific context,'" adding that "a Daubert analysis" 
				applies only where an expert relies "on the application of 
				scientific principles," rather than "on skill- or 
				experience-based observation."  
				o        
				
				
				It concluded that Carlson's testimony, which it viewed as 
				relying on experience, "falls outside the scope of Daubert. 
				  | 
				  
				
				Applies to All expert testimony 
				o        
				
				
				Rule 702 makes no relevant distinction between "scientific" 
				knowledge and "technical" or "other specialized" knowledge. It 
				makes clear that any such knowledge might become the subject of 
				expert testimony.  
				o        
				
				
				In Daubert, the Court specified that it is the Rule's word 
				"knowledge," not the words (like "scientific") that modify that 
				word, that "establishes a standard of evidentiary reliability." 
				509 U.S. at 589-590.  
				o        
				
				
				Hence, as a matter of language, the Rule applies its reliability 
				standard to all "scientific," "technical," or "other 
				specialized" matters within its scope. 
				  
				
				Daubert said 702 and 703 granted expert witnesses testimonial 
				latitude 
				o        
				
				
				Daubert pointed out that Federal Rules 702 and 703 grant expert 
				witnesses testimonial latitude unavailable to other witnesses on 
				the "assumption that the expert's opinion will have a reliable 
				basis in the knowledge and experience of his discipline." 
				 
				  
				
				There is no clear line that divides scientific from technical 
				knowledge 
				o        
				
				
				Finally, it would prove difficult, if not impossible, for judges 
				to administer evidentiary rules under which a gatekeeping 
				obligation depended upon a distinction between "scientific" 
				knowledge and "technical" or "other specialized" knowledge.
				 
				  
				
				Daubert's general principles - testimony must have a reliable 
				basis in the knowledge and experience of the relevant discipline 
				o        
				
				
				Apply to the expert matters described in Rule 702.  
				o        
				
				
				The Rule, in respect to all such 
				matters, "establishes a standard of evidentiary 
				reliability."  
				o        
				
				
				It requires a valid connection to the pertinent inquiry as a 
				precondition to admissibility. 
				o        
				
				
				The trial judge must determine whether the testimony has "a 
				reliable basis in the knowledge and experience of [the relevant] 
				discipline 
				  
				
				District Court concluded Carlsons Methodology was unreliable 
				
				(1)  
				
				
				that "none" of the Daubert factors, including that of "general 
				acceptance" in the relevant expert community, indicated that 
				Carlson's testimony was reliable.  
				
				(2)  
				
				
				that its own analysis "revealed no countervailing factors 
				operating in favor of admissibility which could outweigh those 
				identified in Daubert. 
				
				(3)  
				
				
				that the "parties identified no such factors in their briefs. 
				o        
				
				
				For these three reasons taken together, it concluded that 
				Carlson's testimony was unreliable 
				  
				
				No indication other industry experts use Carlsons two factor 
				test 
				o        
				
				
				We have found no indication in the record that other experts in 
				the industry use Carlson's two-factor test or that tire experts 
				such as Carlson normally make the very fine distinctions about, 
				say, the symmetry of comparatively greater shoulder tread wear 
				that were necessary, on Carlson's own theory, to support his 
				conclusions.   
				o        
				
				
				Nothing in either Daubert or the Federal Rules of Evidence 
				requires a district court to admit opinion evidence that is 
				connected to existing data only by the ipse dixit of the expert. 
				  
				
				Court 
				- Holding 
				o        
				
				
				District Court did not abuse its discretionary authority 
				o        
				
				
				Court of Appeals reversed
