WILLIAMS, J.

The matter-of-fact and unpretentious trial and appellate history of this case attests to the acceptance and confidence of the American people in the ability and integrity of the judiciary to exercise the authority of judicial supremacy in determining and delineating the basic constitutional doctrine of separation of legislative, executive and judicial powers. It is an awesome power and responsibility and must be exercised both courageously and with understanding and restraint.

There are two issues in this case:

I. Does the Court of Appeals have jurisdiction to entertain a complaint for superintending control which charges that a trial judge acted without authority in accepting, over the objection of the prosecutor, a plea of guilty to an offense not charged by the people or included within the offense charged in the information?

II. Does a trial judge have the authority to accept an offer and plea of guilty over the objection of the prosecutor to an offense not charged or included in the information?

The defendant, Dana McBride, was bound over to the Genesee Circuit Court after a preliminary examination to stand trial on an information charging possession of a stolen motor vehicle in violation of MCLA 257.254; MSA 9.1954. On the day the case was to go to jury trial the trial judge, apparently on the basis of a previous discussion with defendant and his counsel, granted defendant's motion that he be allowed to plead guilty to unlawfully driving away the automobile of another in violation of MCLA 750.413; MSA 28.645. Before final acceptance of the plea the trial judge asked the prosecutor, "I take it, Mr. Prosecutor, you are not going to make objections to this". The prosecutor indicated that the facts supported the charge as originally bound over and that he intended to proceed to trial on the charge as bound over because it was a more serious offense than the typical "joy riding" case. In overruling the prosecutor's objection the judge said "Fine, but, Mr. Prosecutor, how many times have you already come up this term where the evidence would show — so you can't always play God as to which one you are going to permit to plead guilty to a lesser offense or not."

The trial judge proceeded with the plea-taking procedure wherein the defendant admitted that he had stolen a Volkswagen similar to his own, driven it away, exchanged the license plates with his own and taken the car to a farm. The judge concluded: "Actually, you are really guilty of the higher offense, but the court will accept your plea to the lesser offense." Subsequently, McBride was sentenced to 3-1/2 to 5 years at Jackson with execution suspended provided McBride entered the army. The army did not accept McBride and the original sentence was reinstated. Defendant was advised of his rights to appeal, "indigent" counsel and transcript. Claim of appeal was filed in the Court of Appeals and defendant has been admitted to bail pending decision in that Court.

In a separate proceeding, the prosecution sought a writ of superintending control from the Court of Appeals challenging the trial court's right over the prosecutor's objection to accept a plea to an offense not charged nor a lesser included offense. This request was "dismissed for lack of jurisdiction", on the ground that the proceeding was not one of the "appeals" authorized by statute, citing MCLA 770.12; MSA 28.1109 and Wayne County Prosecutor v Recorder's Court Judge. The people, upon leave granted, ask this Court to hold that the Court of Appeals has jurisdiction to entertain complaints for superintending control under facts such as these and further that we retain jurisdiction of the cause and enter an order of superintending control directing the defendant judge to vacate defendant McBride's guilty plea and sentence and reinstate criminal proceedings based on the information charging violation of MCLA 257.254.

I. — Jurisdiction

In response to the Court of Appeals holding that this proceeding was not an authorized "appeal" under the statute (MCLA 770.12) the people answer that they do not claim the action of the trial judge is reviewable by an "appeal" under MCLA 770.12. The people in effect contend that a writ of superintending control under GCR 1963, 711.3 is not an appeal but rather is an original civil action, here in the nature of mandamus, and as such is a proper method for correcting abuses of jurisdiction by a trial judge.

In People v Brundage, 381 Mich. 399, 403 (1968), Justice O'HARA writing in a portion of his dissent concurred in by the majority, addressed the relationship between the limited rights of "appeal" under MCLA 770.12 and the writ of superintending control. Speaking of the statute he said:

"We feel obligated to point out that as an expression of legislative policy we accord the statute great weight. However, to the extent that it purports to limit our appellate jurisdiction, it is constitutionally infirm. Our appellate jurisdiction is constitutional. It can neither be enlarged nor restricted by legislative action. The Constitution provides:

"`The Supreme Court shall have * * * power to issue * * * prerogative and remedial writs; and appellate jurisdiction as provided by rules of the supreme court.' (Emphasis supplied.)" (Footnote omitted.)

Pursuant to the Constitution this Court adopted GCR 1963, 711.3 which supercedes the writs of certiorari, mandamus and prohibition, providing one simplified procedure for reviewing or supervising the actions of lower courts and tribunals.

The use of the office of superintending control by the people in a criminal case to review excesses of jurisdiction was considered by this Court in People v Flint Municipal Judge, 383 Mich. 429 (1970). In that case the prosecutor filed a complaint for superintending control against a municipal judge alleging an abuse of discretion in failing to bind over a defendant for trial. The Court recognized that the writ of superintending control was a proper method for reviewing a claimed abuse of discretion by the trial judge but affirmed the Court of Appeals' denial of the complaint on the ground that GCR 1963, 711.4 required the writ to be addressed to the first tribunal having competence to hear and act upon it (in that case the circuit court). On the propriety of the use of the writ by the people in these circumstances, however, Chief Justice T.E. BRENNAN said for a unanimous court:

"No argument is made here as to the proper office of superintending control as a means of reviewing the discretion of an examining magistrate. The order of superintending control embraces the functions of the former writ of mandamus. GCR 1963, 711.3 (2).

"Superintending control, like mandamus, lies to require the magistrate to perform a function where the magistrate has a clear legal duty to act.

* * *

"The process is not, properly speaking, an appeal. It is rather a whole new lawsuit, with different parties and different purposes. People v Yeotis is not a criminal case, but is rather an original civil complaint designed to require the defendant municipal judge to perform a clear legal duty." 383 Mich. 429, 431-432.

The Supreme Court has by GCR 1963, 711 provided that the Court of Appeals has the power to issue superintending control orders which are in the nature of certiorari, mandamus and prohibition.

This superintending control has nothing to do with the general supervisory superintending control over all courts given to the Supreme Court by art 6, § 4 of the 1963 Constitution or the supervisory and general control over inferior courts and tribunals within their respective jurisdictions in accordance with rules of the Supreme Court, given the circuit courts by art 6, § 13 of the 1963 Constitution.

No general control of inferior courts exists in the Court of Appeals.

Whether this action be viewed in the nature of certiorari, mandamus, or prohibition the writ of superintending control would lie. The writ of certiorari is for review of errors of law and our inquiry is limited to determining "if the inferior tribunal, upon the record made, had jurisdiction, whether or not it exceeded that jurisdiction and proceeded according to law". In re Fredericks, 285 Mich. 262, 267 (1938). In Flint Municipal Judge, supra, we noted that mandamus would lie to require the magistrate to perform a clear legal duty. Here it is contended that the judge acted without jurisdiction and therefore has a clear legal duty to vacate the guilty plea and reinstate the criminal proceedings as filed in the information. The writ of prohibition is a common-law remedy designed to prevent excesses of jurisdiction. It is a proper remedy where the court exceeds the bounds of its jurisdiction or acts in a matter not within its jurisdiction. Hudson v Judge of Superior Court, 42 Mich. 239, 248 (1879). In this case the facts alleged also support a complaint for a writ of superintending control in the nature of prohibition.

In People v Flint Municipal Judge, supra, the magistrate indisputably had jurisdiction to exercise discretion with respect to the sufficiency of the evidence to bind over the defendant. Without passing on the merits, however, this Court said that the writ of superintending control is a proper method for the people to seek review of the discretion of the examining magistrate.

If the writ may be used to review an exercise of discretion where it is unquestioned that the judge had the power to exercise some discretion then, a fortiori, the writ may be used to review the action of a lower court when it is claimed that the court lacked the power to exercise any discretion with respect to the ruling in question.

The Court of Appeals had jurisdiction to entertain the complaint for superintending control for the purpose of determining whether the trial judge acted without jurisdiction or in excess of jurisdiction. Since the cause is now properly before us we retain jurisdiction under our power of superintendence, Const 1963, art 6, § 4.

II. — The Authority of the Trial Judge to Amend the Information and Accept a Plea Over the Objection of the Prosecutor

Whether the trial judge may amend an information and accept a plea sua sponte and over the objection of the prosecutor raises the question of constitutional separation of powers between the judicial and executive branch.

At the outset we note that we are not concerned here with the power of a trial judge to permit the amendment of an information where there is no objection by the prosecutor and the defendant waives any necessary arraignment and examination. In addition, because of the trial judge's determination that McBride was "actually guilty of the higher offense", we are not concerned with any question of the scope of authorized power under MCLA 767.76; MSA 28.1016 to amend informations for technical defects or because of variance with the evidence.

The sole question here is whether the trial judge on her own initiative has the power to determine, over the objection of the prosecutor, under which of two admittedly-applicable statutes a prosecution will be instituted, where neither statute represents a lesser included offense of the other.

The prosecutor is a constitutional officer whose duties are as provided by law. Const 1963, art 7, § 4. Lawrence Scudder Co v Emmet County, 288 Mich. 181, 184 (1939); Schneider v Shepherd, 192 Mich. 83, 88 (1916). The conduct of a prosecution on behalf of the people by the prosecutor is an executive act, People v Dickerson, 164 Mich. 148, 153 (1910).

We have held in the past that the prosecutor is the chief law enforcement officer of the county and has the right to exercise broad discretion in determining under which of two applicable statutes a prosecution will be instituted. People v Lombardo, 301 Mich. 451, 453 (1942); People v Thrine, 218 Mich. 687, 690, 691 (1922); People v Mire, 173 Mich. 357, 364 (1912). See also People v Graves, 31 Mich. App. 635, 636 (1971); People v Eineder, 16 Mich. App. 270, 271 (1969); People v Byrd, 12 Mich. App. 186 (1968), concurring opinion of LEVIN, J. at 197, particularly footnote 7; People v Ryan, 11 Mich. App. 559, 561 (1968).

"Acting as prosecutor, judge and jury" is a common description of an unfair and unlawful operation. However innocently and mistakenly, this is what happened in this case. The trial judge assumed the right over the objection of the prosecutor to determine under which of two applicable statutes a prosecution will be instituted. As already indicated such determination is an executive function and a part of the duties of the prosecutor. For the judiciary to claim power to control the institution and conduct of prosecutions would be an intrusion on the power of the executive branch of government and a violation of the constitutional separation of powers. Const 1963, art 3, § 2. It also violates our fundamental sense of fair play.

We therefore hold that the trial judge acted without authority in amending the information over the objection of the prosecutor in this case.

It is to be noted that the trial judge in this case apparently thought her authority to amend the information (adding the count of unlawfully driving away the automobile) was justified by the fact that the added offense was, in her opinion, "lesser included". Unlawfully driving away the automobile of another in violation of MCLA 750.413 is not a lesser offense included in the violation of MCLA 257.254 which proscribes possession of a motor vehicle known to be stolen. For an offense to be lesser included it must contain some, but not all of the elements of the higher offense and there must be no additional elements in the "included" offense which are not a part of the "higher" offense. The supposed "lesser" offense here requires proof of driving away the automobile but proof of "driving away" is not required of the prosecution to secure a conviction of unlawful possession of a motor vehicle known to be stolen. Although related, the two offenses are separate and distinct and the prosecutor has discretion to proceed under one or the other or both, if warranted by the facts. People v Morton, 16 Mich. App. 160 (1969), reversed on other grounds, 384 Mich. 38 (1970); see also People v Kruper, 340 Mich. 114, 121-122 (1954).

In our holding that the judge here acted without authority we express no opinion on the propriety of accepting a plea over the objection of the prosecutor where both offenses are charged by the prosecutor, nor do we express an opinion on the propriety of accepting a plea over the objection of the prosecutor to an offense which is a lesser included offense.

The plea of guilty to MCLA 750.413; MSA 28.645 is annulled and the sentence imposed pursuant to that plea is vacated. The cause is remanded to the trial court for proceedings upon the information as filed by the prosecutor on July 13, 1970.
