Bruce Reid Bacon appeals from a decision of the district court denying his motion to dismiss a charge of misdemeanor driving under the influence. The facts presented to us in this case have been stipulated by the parties.
On April 26, 1987, Bacon was arrested in the city of Buhl for driving under the influence in violation of I.C. § 18-8002. The following day the Twin Falls County Attorney filed a complaint in case number 176612 charging the defendant with felony DUI. On May 18,1987, a preliminary hearing was held on that charge and the case was dismissed. That same day the prosecuting attorney refiled the identical felony DUI charge and the court assigned number 176730 to the case. A second preliminary hearing was held on June 18, 1987, and the defendant was bound over to district court. The Twin Falls County prosecuting attorney moved the district court to appoint a special prosecutor pursuant to I.C. § 31-2603(a) on the grounds that one of the Twin Falls deputy prosecuting attorneys would be a witness. The district court entered an order in the case on August 11, 1987, approving the appointment of the special prosecutor in this case and the case caption on the order referred to it as “Case No. 2564.” On January 25, 1988, the dis*681trict court heard arguments on defendant’s motion to dismiss and ordered dismissal of the information.
The special prosecutor, acting through the Twin Falls County Prosecuting Attorney’s Office, again refiled the felony complaint and the case was scheduled for a preliminary hearing. The court assigned case number 184821 to this proceeding. No application or order for appointment of a special prosecutor was obtained prior to filing case number 184821. A preliminary hearing was held on March 81, 1988, and the case was again dismissed on grounds that the underlying misdemeanor charges were invalid.1
On April 8, 1988, the special prosecuting attorney filed an amended complaint charging the defendant with a misdemeanor DUI occurring on April 26, 1987, in violation of I.C. § 18-8004. This pleading was filed in case number 1848212 and is the subject of the appeal currently before this Court.
The defendant was arraigned on the misdemeanor DUI charge and a not guilty plea was entered by the court. The defendant thereafter filed his motion to dismiss the amended complaint. The magistrate court denied Bacon’s motion to dismiss on June 6, 1988, and on July 5, 1988, Bacon entered a conditional plea of guilty to the misdemean- or charge. The court entered judgment of conviction consistent with the conditional plea agreement and stayed imposition of sentence pending appeal to the district court. On February 13, 1989 the district court upheld the magistrate’s decision.3
On appeal to this Court, Bacon contends 1) that the special prosecutor lacked authority to amend and refile the complaint as a misdemeanor; 2) that the amended complaint filed under the case number of a previously dismissed case is invalid, and 3) that the refiling of charges on three occasions constitutes harassment.
I.
Appointment of Special Prosecutor
The first issue presented is whether the special prosecutor had legal authority to amend the charges to a misdemeanor DUI after the case in which he was appointed had been dismissed.
Criminal complaints can be filed by either a duly elected or appointed prosecuting attorney for the political body initiating the criminal charge. Former I.C. § 31-2603, which was in effect at the time of the appointment of the special prosecutor in this case, does not limit a special prosecuting attorney’s role to a specifically named and filed case. The pertinent portion of the statute providing for appointment of the special prosecutor stated:
[T]he district court may ... appoint some suitable person to perform for the time being, or for the trial of such accused person, the duties of such prosecuting *682attorney, and the person so appointed has all the powers of the prosecuting attorney, while so acting as such.
The special prosecutor had the same power as the elected prosecutor to file a lesser charge against the defendant where the court previously dismissed the felony charge. A challenge to the authority of a special prosecutor was made in State v. Corcoran, 7 Idaho 220, 61 P. 1034 (1900), wherein the Supreme Court then held that even if the trial court mistakenly appointed a special prosecutor his acts were those of an officer de facto and were entitled to recognition as such. The Court in Corcoran concluded that the result would have been no different if some other suitable person had acted as prosecutor instead of the person so appointed.
The magistrate judge in the present action correctly observed in his memorandum decision that better practice would be to have an order from the district court appointing the special prosecutor in each of the new files. However, as both the magistrate judge and the district court ruled, that procedure is not necessary or required under the circumstances presented. Although the proceedings against Bacon were brought in four separate pleadings, the substance of the charges remained the same throughout the entire process, all having arisen out of the April 26, 1987 operation of his vehicle and subsequent arrest.
I.C. § 31-2603 allowed for “the appointment of a special assistant attorney-general to assist in the prosecution of any criminal case.” Bacon, however, requests that this Court narrowly interpret the motion and order of appointment and limit the involvement of the special prosecutor only to case number 6524 in which he was appointed. We decline to do so and interpret I.C. § 31-2603 to allow appointment by the district court of a special prosecutor to assist in the state’s case against a particular defendant in all related proceedings rather than limit the appointment to a court file bearing a particular case number.
In Clark v. Meehl, 98 Idaho 641, 570 P.2d 1331 (1977), this Court held that it is immaterial whether the person filing a complaint before a magistrate is acting as a private citizen or on behalf of a public officer. We hold that the special prosecutor, once appointed by the district court, had power and authority to file and pursue all related charges, just as if he had been the duly elected prosecuting attorney.
II.
Sufficiency of Amended Complaint
Defendant next asserts that once a case has been dismissed no further complaints or pleadings may be filed in that particular numbered case without leave of court, and that use of the case number from the dismissed case was not justified. Consequently, defendant argues without citing any authority that the amended complaint filed by the special prosecutor charging a misdemeanor DUI is void.
Bacon urges this Court to declare the amended complaint void because the special prosecutor did not obtain leave of court prior to its filing. The record demonstrates that following dismissal of the felony charges in case number 184821, the special prosecutor presented the amended complaint for subscription to the same magistrate who had dismissed the felony charge several days earlier. The magistrate subscribed the amended complaint and it was filed in case number 184821. We hold that the magistrate’s subscription of the amended complaint in this case to be the equivalent of leave of court. Based on the record presented to us we find no prejudicial error in the procedure followed in filing the amended complaint.
I.C.R. 12(c) addresses the content of criminal pleadings and provides in pertinent part: “Every pleading ... shall contain a caption setting forth the names of the parties, the title of the district court, together with the assigned number of the action____” A legally sufficient, valid *683criminal complaint need only be a simple and concise statement of the essential facts constituting the offense charged. State v. Owens, 101 Idaho 632, 619 P.2d 787 (1979) (overruled on other grounds). By way of analogy to civil actions, we have held that the character and nature of a pleading is to be determined from the substance of the facts therein alleged and not from what the pleading may have been designated or called by the party. First Savs. Bank of Pocatello v. Sherman, 33 Idaho 343, 195 P. 630 (1920).
Bacon contends that the use of several different case numbers, including one from a previously dismissed case, was prejudicial. The mistaken use of case number 6524 on the order appointing the special prosecutor, and use of a case number on the amended complaint from a previously dismissed case is not prejudicial to Bacon. I.C.R. 36 addresses the effect of mistakes or errors in court records and states:
Clerical mistakes — Clerical mistakes in judgments, orders or other parts of the record and errors in the record arising from oversight or omission may be corrected by the court at any time and after such notice, if any, as the court orders.
In addition, I.C. § 19-3702 provides that neither a departure from the form of a pleading, nor a mistake or error therein, renders it invalid unless actual prejudice to the defendant occurs. This section is recognized as an admonition against reliance upon technical errors as the basis for reversal of judgments. See State v. Stevens, 93 Idaho 48, 454 P.2d 945 (1969).
Although the preferred manner of proceeding would have been to file a new case altogether rather than filing an amended complaint, merely having different or incorrect case numbers on the complaint or pleadings as a result of either a clerical or typographical error, or use of a number from a previously dismissed case on the amended complaint, is not sufficient cause to invalidate the complaint. This is particularly true where there is only one event giving rise to the charges contained in all pleadings, i.e., Bacon’s operation of his motor vehicle on April 26, 1987. The use of several different case numbers on the various pleadings, including use of the number from a previously dismissed case, has not been shown to have caused or resulted in any error or prejudice to Bacon.
III.
Refiling of Charges
Bacon contends by refiling the charges against him that the state is using the judicial process to harass him and consequently denied him due process of law.
In State v. Ruiz, 106 Idaho 336, 678 P.2d 1109 (1984), we held upon dismissal of a criminal complaint that the prosecution could file a new complaint. Similarly, in Stockwell v. State, 98 Idaho 797, 573 P.2d 116 (1977), this Court held where the charges were reduced at a preliminary hearing that it was permissible for a prosecutor to dismiss the case and refile the original charge. The Court in Stockwell noted that dismissal and refiling of criminal complaints, if done for the purpose of harassment or delay, could be a violation of due process. In Ruiz, this Court has held that once a complaint is dismissed,
[T]he State could have simply filed another complaint with another, magistrate, in effect, having its assertion of error resolved in a new preliminary hearing ... The State was not barred under double jeopardy principles from refiling since an accused is not put in jeopardy at a preliminary hearing. (Citations deleted) ... [T]he only limit to refiling a complaint is that it cannot be done without good cause or in bad faith.
106 Idaho at 377, 678 P.2d at 1110-11.
In the instant case, the first felony case against Bacon was dismissed following a preliminary hearing. The prosecutor then refiled the charges and prevailed in having Bacon bound over to district court. All three felony charges failed only because of technical inadequacies in the underlying misdemeanor DUI convictions rather than as a result of lack of evidence or merit. There is nothing in the record that shows purposeful harassment and the refiling of the various charges under these circumstances does not of itself establish *684harassment. Stockwell requires the existence of bad faith to prove a per se due process violation. See also Rufener v. Shaud, 98 Idaho 823, 573 P.2d 142 (1977). Neither the magistrate court nor the district court found any evidence of bad faith and our independent review of the record confirms those findings.
The decision of the district court is affirmed.
BAKES, C.J., and JOHNSON and McDEVITT, JJ., concur..All of the felony charges were dismissed as a result of technical dificulties in the underlying misdemeanor convictions. Although different case numbers were given to the several cases, all charges and proceedings against Bacon arose out of the April 26, 1987 arrest.
