This is an original proceeding filed pursuant to C.A.R. 21. The petitioners seek to prohibit the respondent district court from proceeding against them in two criminal cases which were commenced after the court granted the district attorney’s request to file direct informations. The informa-tions charge the petitioners with the identical crimes that were dismissed by the county court for lack of probable cause following a preliminary hearing. We issued a rule to show cause and now make the rule absolute.
I.
The petitioners, James Holmes (Holmes) and Travis Kellner (Kellner), were charged by felony complaints filed in the Summit County Court with distribution of a schedule II controlled substance1 and conspiracy to distribute a schedule II controlled substance.2 According to the sparse record before us, the charges arose out of the alleged sale of cocaine by Kellner to a police informant at a bar in Breckenridge, Colorado.
A preliminary hearing was held in the county court on March 16, 1983. Detective A1 Kiburas was the only witness called by the prosecution. Apparently, Detective Ki-buras testified about what he personally observed during the transaction and subsequent events. He also testified as to statements made to him by the informant, David Gagne, who was present in the courtroom but did not testify. At the conclusion of the preliminary hearing, the county judge found no probable cause on both counts against Holmes and dismissed the charges. The county court also found no probable cause on the conspiracy charge against Kellner, but bound him over to the district court for trial on the crime of distribution of a schedule II controlled substance.
On March 18,1983, the date set for Kell-ner’s arraignment in the district court, the district attorney requested leave to file a direct information charging the petitioners with the identical charges that had been dismissed by the county court. The district attorney informed the court that the original charges had been dismissed by the county court because no probable cause was found. The prosecutor told the respondent judge that he made a tactical decision not to call the informant as a witness at the preliminary hearing. He stated that there would be new and additional evidence for á district court preliminary hearing because Gagne would provide direct evidence concerning the alleged crimes, rather than the hearsay testimony which had been presented by Detective Kiburas.
The respondent judge granted the district attorney’s request for leave to file direct informations against the petitioners. The petitioners then filed a motion to dismiss the informations. In denying the petitioners’ motion to dismiss, the respondent judge stated:
“I nonetheless think that since the District Attorney has indicated that there is additional evidence, that it is in the nature of direct evidence rather than hearsay evidence, that I don’t think I was erroneous in permitting the direct bind-over, and having reconsidered, I am not going to dismiss the charges on the basis that I properly accepted.”
After the motion was denied, the petitioners filed this original proceeding.
II.
When the county court dismisses a felony complaint after holding a preliminary hearing pursuant to Crim.P. 5(a)(4)(IV), the sole remedy available to the prosecution is requesting permission of the district court to file a direct information in *14accordance with Crim.P. 7(c)(2).3 Crim.P. 5(a)(4)(V) states that “[dismissal of a felony complaint following a preliminary hearing shall not be a bar to a subsequent filing of a direct information in the district court charging the defendant with the same offense.” See People v. Burggraf, 86 Colo. App. 137, 536 P.2d 48 (1975). Therefore, under Crim.P. 7(c)(2), the district attorney, with the consent of the court, may file a direct information in the district court if a preliminary hearing was held on the same charge in the county court and the accused was discharged. The issue presented here is whether the respondent judge abused his discretion in permitting the direct filing based on the prosecuting attorney’s statements that he would present new or additional evidence in the form of direct rather than hearsay testimony. See People v. Elmore, 652 P.2d 571 (Colo.1982).
A.
The requirement of court consent prescribed by Crim.P. 7(c)(2) “implies a real application of discretion.” People v. Swazo, 191 Colo. 425, 427, 553 P.2d 782 (1976). Before the district court may properly exercise its discretion, there must be a sufficient evidentiary disclosure by the prosecution to apprise the district court of the earlier dismissal of the identical charges in the county court and the reasons for the requested re-filing. When exercising its discretion in deciding whether to permit the direct filing of an information under Crim.P. 7(c)(2), the district court is required to balance the right of the district attorney to prosecute criminal cases against the need to protect the accused from discrimination and oppression. People v. Freiman, 657 P.2d 452 (Colo.1983).
The respondent judge premised his decision to allow the direct filings on the ground that direct rather than hearsay evidence constitutes new or additional evidence. The focus of the parties’ briefs is also directed to the new or additional evidence theory. However, we note that Crim.P. 7(c)(2) does not require a showing of new or additional evidence. The new or additional evidence requirement is found in Crim.P. 7(h)(5) which states that the “granting of such a motion [for dismissal] shall not be a bar to further prosecution of the accused person for the same offense if new or additional evidence is found by the prosecution.” This provision applies only to preliminary hearings held in the district court. See People v. Anderson, 659 P.2d 1385 (Colo.1983). Crim.P. 7(c)(2) contains no requirement that the district attorney establish that there now exists new or additional evidence to support the direct filing of an information. The existence of such evidence is only one factor the district court may consider in exercising its discretion to determine whether to allow the direct filing.
B.
In applying these principles to the facts of this case, we hold that the respondent judge abused his discretion in permitting the filing of the direct informations. The only argument made by the district attorney was that he would produce direct rather than hearsay evidence at the preliminary hearing held in the district court. The district attorney did not specifically advise the respondent judge of any facts to which the informant would testify that had not already been the subject of hearsay testimony by Detective Kiburas in the county court. Nor did the district attorney specify how the county court may have erred legally or factually in not finding the existence of probable cause on the three charges it dismissed. Moreover, the informant was available in the courtroom during the preliminary hearing held by the county judge. The district attorney candidly admits he made a tactical decision not to call the *15informant and subject him to cross-examination. The People, rather than the petitioners, must bear the burden of that decision.
A preliminary hearing provides the accused with an opportunity to challenge the sufficiency of the People’s evidence at an early stage in the proceedings. People ex rel. Farina v. District Court, 185 Colo. 118, 522 P.2d 589 (1974). The preliminary hearing is designed to weed out groundless or unsupported charges and to relieve the accused of the degradation and expense of a criminal trial. Maestas v. District Court, 189 Colo. 443, 541 P.2d 889 (1975); People v. Superior Court of Marin County, 33 Cal.3d 754, 661 P.2d 1081, 191 Cal.Rptr. 1 (1983). At the preliminary hearing, the prosecution has the burden of producing that quantum of evidence necessary to establish probable cause to believe that a crime was committed and that it was committed by the defendant. Hunter v. District Court, 190 Colo. 48, 543 P.2d 1265 (1975); Maestas v. District Court, supra; People v. Quinn, 183 Colo. 245, 516 P.2d 420 (1973). The effect of allowing a direct filing in a case where the district attorney states that he will offer direct rather than hearsay testimony would constitute approval of the undesirable practice of presenting as little evidence as possible at the preliminary hearing in the county court and then requesting district court consent for a direct filing if no probable cause is found by the county court.4 This duplicative procedure unnecessarily taxes already strained judicial resources and subjects the accused to oppression and discrimination. People v. Freiman, supra. If the People may file a direct information in the district court simply because they made a tactical error at the preliminary hearing in the county court, there is little incentive to comply with the requirements governing preliminary hearings set forth in the Rules of Criminal Procedure and interpreted in case law.5 See Chavez v. District Court, 648 P.2d 658 (Colo.1982). Accordingly, the petitioners may not be prosecuted on the direct infor-mations filed in Case Nos. 83CR15 and 83CR16 filed in the District Court of Summit County.
The rule is made absolute.
