Sanders did not establish a prima facie Sixth Amendmennt violation because he showed that Hispanics were underrepresented on his jury. Although the Hispanics in the jury venire were represented by half of the representation of Hispanics in the general population of Kern County, the methodology used by Sanders was flawed in that it assumed that every Hispanic person in Kern County was a jury eligible United States citizen. Therefore, the court was unable to determine whether the systematic exclusion of a distinctive group kept it from being fairly represented on the jury.
