Holding

Based on all the facts that bear on the grand jury discrimination issue, such as the statistical disparties (the county population was 79% Mexican-American, but, over an 11-year period, only 39% of those summoned for grand jury service were Mexican-American), the method of jury selection, and any other relevant testimony as to the manner in which the selection process was implemented, the proof offered by respondent was sufficient to demonstrate a prima facie case of intentional discrimination in grand jury selection, and the State failed to rebut such presumption by competent evidence.
