The appeal is from a conviction by jury for murder in the second degree. We reverse and remand for new trial on the principle of
Duren v. State of Missouri,
439 U.S. -,
At commencement of trial the defendant moved quashal of the jury venire on the grounds that the procedures by law [Article I, § 22(b) of the Missouri Constitution of 1945 and § 494.031, RSMo 1969)] which exempt from service as a juror any woman who requests excuse on account of gender deny a right to jury by a representative segment of the community in violation of the Sixth and Fourteenth Amendments to the United States Constitution. The motion was accompanied by a stipulation that the method used by the Jury Commissioner of Jackson County to devise the jury wheel for the year 1976 was employed for the year 1977. The stipulation was amplified by an agreed incidence of statistics [between January and July of that year] of women who claimed gender exemption and, ultimately, the numbers by gender which made up the wheel. The motion for quashal of the ve-nire was denied by the trial court and the proceeding went to judgment and conviction.
The same challenge [but on a statistical incidence between June-October of 1975 and January-March of 1976] was made to the petit jury venire, and rejected, in
State v. Duren,
The defendant contends that the United States Supreme Court opinion in Duren, made retrospective by effect, determines his contention for reversal. It is the contention of the State, however, that neither the statistical data for Duren [which dealt with the jury wheel and venire compositions for segments of the years 1975 and 1976] nor the statistical data by stipulation [as to the jury wheel composition for the first seven months of 1976] determines a comparable discriminatory effect for the petit jury pool for 1977, when the defendant was tried.
We have rendered opinions concurrently to reverse and remand criminal convictions returned in 1977 on a stipulation by the prosecution that the method used to devise the Jackson County petit jury wheel was that employed in year 1976 [State
v. Tate,
Quite apart from these rationales, where a defendant has raised and preserved the contention of gender discrimination in the petit jury selection process,
Duren
requires reversal of a year 1977 conviction by a Jackson County jury, without further proof of an underrepresented venire [
[The] undisputed demonstration that a large discrepancy occurred not just occasionally but in every weekly venire for a period of nearly a year manifestly indicates that the cause of the underrepre-sentation was systematic — that is, inher *337 ent in the particular jury-selection process utilized.
We understand that to mean that a jury selection system installed by law gender-discriminatory in method and gender-discriminatory by prolonged practice [the 1975 and 1976 base period proven in Duren] is deemed to continue until shown abated by the State.
That the Missouri Supreme Court shares our understanding is evident from its mandate for reversal and new trial entered in
State v. Arrington,
The discriminatory method of jury selection and the incidence of discriminatory venires in Jackson County proven at the time Duren was tried persisted into year 1977 when the defendant Coleman was tried. The defendant on his timely motion was entitled to a quashal of the petit jury venire by which he was convicted.
The judgment is reversed and remanded for new trial.
All concur.
