In Crawford v. Washington (2004) 541 U.S. 36 [ 158 L.Ed.2d 177 , 124 S.Ct. 1354 ] (Crawford), the United States Supreme Court held, with exceptions not relevant here, that the admission of testimonial hearsay against a criminal defendant violates the Sixth Amendment right to confront and cross-examine witnesses. Here we consider the degree to which the Crawford rule limits an expert witness from relating case-specific hearsay content in explaining the basis for his opinion. In addition, we clarify the proper application of Evidence Code sections 801 and 802, relating to the scope of expert testimony.

We hold that the case-specific statements related by the prosecution expert concerning defendant’s gang membership constituted inadmissible hearsay under California law. They were recited by the expert, who presented them as true statements of fact, without the requisite independent proof. Some of those hearsay statements were also testimonial and therefore should have been excluded under Crawford. The error was not harmless beyond a reasonable doubt. Accordingly, we reverse the jury findings on the street gang enhancements.
