Whether Duren established a prima facie violation of the Sixth Amendment fair-cross-section requirement.
Holding
Yes. Women are a distinctive group, their roughly 14.5% representation on Jackson County venires was not fair and reasonable compared with their 54% share of the adult community, and the disparity was systematic.
Reasoning
The Sixth Amendment, applied to the States through the Fourteenth Amendment, requires that the jury wheel, pool, panel, or venire from which petit juries are selected be drawn from a fair cross section of the community. It does not require that the petit jury actually chosen mirror the community. To make a prima facie showing, a defendant must establish that the excluded group is distinctive, that its representation on venires is not fair and reasonable relative to its community representation, and that the underrepresentation results from systematic exclusion in the selection process.
Taylor v. Louisiana had already established that women are a sufficiently numerous and distinctive group for fair-cross-section purposes. Thus, systematic elimination or substantial systematic underrepresentation of women on jury panels cannot satisfy the Sixth Amendment requirement.
Duren’s undisputed statistics adequately established the relevant benchmark and the disparity. The State had not challenged the 1970 census data at trial, and the Missouri Supreme Court’s speculation about population changes or possible differences in voter registration did not undermine the evidence. With women constituting about 54% of the adult population, venires that were only about 14.5% female were grossly unrepresentative: fewer than one in six prospective jurors was female, while more than one in two adults in the community was female.
The disparity was systematic because it recurred in every weekly venire over nearly a year, rather than appearing as an isolated result of random selection. The evidence also identified where the disparity arose. Women were not shown to be underrepresented in the original questionnaire mailing, but their share fell below 30% among persons summoned and then to 14.5% among those appearing. Missouri’s opt-out exemption for women, coupled with Jackson County’s practice of treating a woman’s failure to appear as a claim of exemption, made the underrepresentation inherent in the jury-selection system.
