In this special action, petitioner seeks to compel the Honorable Harold L. Kautz, Judge of the City Court of the City of Phoenix, to grant him a trial by jury on the charge of simple assault and battery. We accepted jurisdiction pursuant to the Constitution of Arizona, Article 6, § 5, A. R.S., and Rule 2 of Special Actions, Rules of Procedure, 17A A.R.S. After further consideration, we have concluded that the petition should be. ordered dismissed and it is so ordered.
Petitioner was charged in the City Court of the City .of Phoenix with willfully and unlawfully using force and violence on the person- of another, a violation of a state statute, A.R.S. § 13-241 (B). He timely requested a jury trial, which was denied by the respondent, Judge Kautz. He then petitioned the Superior Court of Maricopa County, asking for a jury trial which was denied, and this special action was brought.
The denial of a jury trial for offenses the punishment for which does not exceed a $300 fine nor six months in jail does not present a federal constitutional question. Baldwin v. New York, 399 U.S. 66, 90 S.Ct. 1886, 26 L.Ed.2d 437 (1970); Duncan v. Louisiana, 391 U.S. 145, 88 S.Ct. 1444, 20 L.Ed. 491 (1968). Nor does the Arizona Constitution, Article 2, § 23, reading: “The right of trial by jury shall remain inviolate.” require a jury trial in petty offenses. Rothweiler v. Superior Court, 100 Ariz. 37, 410 P.2d 479 (1966); State v. Cousins, 97 Ariz. 105, 397 P.2d 217 (1964).
Justices of the peace had jurisdiction at the common law before 1776 to punish simple assaults and simple assaults and batteries summarily without indictment and without trial by jury. State v. Maier, 13 N.J. 235, 99 A.2d 21 (1953). Absent other constitutional requirements, a defendant who did not have the right to trial by jury at the common law does not have the right to such a trial in Arizona under state law for violations of state offenses. O’Neill v. Mangum, 103 Ariz. 484, 445 P.2d 843 (1968).
Petitioner relies on A.R.S. § 22-320, arguing that he is entitled to a jury trial if he demands it. Section 22-320 provides :
“A trial by jury shall be had if demanded by either the state or defendant. Unless the demand is made before commencement of the trial, a trial by jury shall be deemed waived.”
We do not think the quoted section grants a substantive right, but, rather, was intended to be procedural and must be read as meaning that a trial by jury shall be had if demanded in cases where a jury trial is appropriate. If the Legislature intended to grant a jury trial in every case, it would have no doubt said so in plain, explicit language.
The foregoing would be sufficient answer to petitioner’s position were the question presented for the first time to this Court. But this is not the first time we have been called upon to examine into the question propounded. In O’Neill v. Mangum, supra, we considered whether a defendant charged with drunk and disorderly, a misdemeanor and a violation of A.R.S. § 13-379, was entitled to a jury trial. There we said:
“Defendant’s contentions are neither novel nor sustainable. It is old law that the constitutional right to trial by jury does not extend to petty offenses.” 103 Ariz. at 485, 445 P.2d at 844.
and concluded that the offense charged was one which was within the category of petty offenses not requiring a jury trial.
This is not such a case as dictates the overruling of a former precedent. It is to be acknowledged the law should grow and the doctrine of stare decisis should not require a slavish adherence to authority where new conditions require new rules of conduct. However, petitioner does not argue either that conditions have changed or that experience has demonstrated the original decision was wrong. See Leflar, Robert A., Appellate Judicial Opinions, The Overruling Process, Chapter 6, pages 133, et seq. (1974). As Leflar points out, the overruling of a former decision with*433out expressing the reasons for departing from the doctrine of stare decisis carries with it a certain uneasiness because it is an assumption by the present court that it has obtained a knowledge and wisdom denied its predecessors.
Petitioner argues that this is a crime involving moral turpitude and therefore requires a trial by jury. We are not convinced, however, that simple battery involves any appreciable degree of moral turpitude in American society today.
While there is considerable discussion in the briefs concerning whether the ordinances of the City of Phoenix require a jury trial had petitioner been charged with a violation of a city ordinance, we do not find it necessary to answer that question. Petitioner was charged under the state law and whether he could have had a jury trial under a charge of violating a city ordinance is a question we do not need to. reach here.
