delivered the Opinion of the Court.
We granted certiorari in Abbott v. County Court, No. 92CA1202 (Colo.App. July 29, 1993) (not selected for official publication), to decide: (1) whether a defendant who has a preliminary hearing in county court may appeal a finding of probable cause to the district court pursuant to C.R.C.P. 106; and (2) whether, after the district court reversed the finding of probable cause, the People should have appealed the district court’s decision directly to this court. We hold that a district court may not review a county court’s finding of probable cause under C.R.C.P. 106. We also hold that because the People’s appeal followed a C.R.C.P. 106 proceeding, appeal to the court of appeals was proper.
I
David Abbott (Abbott) was charged with sexual assault on a child by one in a position of trust in violation of section 18-3-405.3, 8B C.R.S. (1994 Supp.). At the preliminary hearing held in the county court, the prosecution’s only witness was the investigating officer, Glen Trainor (Trainor). Trainor based his testimony on his interviews with the alleged victim, witnesses, school administrators and the defendant. Trainor also viewed the room where the alleged incident occurred. The victim was not present at the preliminary hearing. The county court found probable cause existed to bind Abbott over to the district court for trial. Abbott sought review by the district court of the probable cause finding pursuant to C.R.C.P. 106(a)(4).1 The district court reviewed the preliminary hearing transcript and dismissed the charges because the People failed to present sufficient evidence to establish probable cause on the sexual contact element of the offense. The People appealed to the court of appeals where that court held that the district court erred by improperly reviewing the county court’s factual finding of probable cause. Abbott, No. 92CA1202, slip op. at 3. Further, it held that since the district court could not properly review a county court’s factual findings of probable cause, it was in the same position as the district court. The court of appeals reversed and remanded the case to the district court with directions to reinstate the charge.

At issue is the proper procedure for review of a county court’s finding of probable *732cause. Abbott argues that a defendant who has a preliminary hearing in a county court should be allowed to appeal a finding of probable cause to the district court pursuant to C.R.C.P. 106(a)(4). We disagree.
To establish probable cause at a preliminary hearing the prosecution must present evidence sufficient to induce a person of ordinary prudence and caution to entertain a reasonable belief that the defendant committed a crime. E.g., People v. District Court, 803 P.2d 193, 196 (Colo.1990). Crim.P. 5(a)(4)(H) provides that “[t]he judge presiding at the preliminary hearing may temper the rules of evidence in the exercise of sound judicial discretion.” We have long held that a court can find probable cause based largely upon hearsay testimony. See, e.g., People v. Quinn, 183 Colo. 245, 516 P.2d 420 (1973). We have also explained reliance on hearsay evidence must not be abused. Maestas v. District Court, 189 Colo. 443, 541 P.2d 889 (1975).2 All evidence presented in a preliminary hearing must be viewed in the light most favorable to the prosecution, and all inferences must be resolved in favor of the prosecution. See People v. Jensen, 765 P.2d 1028, 1030 (Colo.1988). “Ordinarily, a probable cause determination will not even be reviewed.” People ex rel. Leidner v. District Court, 198 Colo. 204, 207, 597 P.2d 1040, 1042 (1979) (citing Kuypers v. District Court, 188 Colo. 332, 336, 534 P.2d 1204, 1206 (1975)).
We first considered the issue of district court review of a county court’s probable cause findings in People v. District Court, 652 P.2d 582, 585 (Colo.1982) where we held that a district court cannot properly review a county court’s finding of probable cause. There, we examined the plain language of Crim.P. 5 which provides “[i]f the county judge finds probable cause, ‘he shall order the defendant bound over to the appropriate court of record for trial.’ ” Id. (quoting Crim.P. 5(a)(4)(III)) (emphasis supplied). We explained “ ‘[t]his mandate precludes subsequent reexamination or reflection. There is no provision for rehearing on or reconsideration of a ruling on completion of a preliminary hearing. In short, respondent court has no "jurisdiction to later reopen the matter after bind-over to reduce the charges.’ ” Id. (quoting People ex rel. Russel v. District Court, 186 Colo. 136, 526 P.2d 289 (1974) (finding a district court did not have authority to later reopen or reconsider its own finding of probable cause)). We held the Russel rationale applied equally to a district court’s review of a county court’s finding of probable cause. Id. This decision reflected our belief that the objectives of a preliminary hearing would be undermined if “appellate courts were to second-guess the discretionary first-hand assessments of trial courts and substitute their evaluations of testimony based on cold transcripts.” People ex rel. Leidner, 198 Colo. at 207, 597 P.2d at 1042; see also People ex rel. Gallagher v. Arapahoe County Court, 772 P.2d 665, 666 (Colo.App.1989) (District court cannot review a county court’s finding of no probable cause.).
In White v. MacFarlane, 713 P.2d 366, 368 (Colo.1986), we affirmed this rule, holding that a “district court does not have jurisdiction to reopen or reconsider a county court’s probable cause determination.” This ruling does not, however, leave the defendant without a remedy because “[a] defendant seeking to challenge an erroneous ruling on probable cause may seek extraordinary relief under C.A.R. 21.” White, 713 P.2d at 368-69.3
*733B
Despite this precedent Abbott elected not to seek review under C.A.R. 21. Instead, he contends that since the district court based its review strictly upon the prosecution’s failure to present testimony of a perceiving witness, review under C.R.C.P. 106 is proper.4 We disagree. The district court did not reverse because only hearsay testimony was presented; it reversed based on the content of the testimony, and a lack of evidence on the sexual contact element of the offense.
We are not persuaded by Abbott’s attempt to recast the district court’s reversal into a procedural ruling.5 Abbott relies on Zaharia v. County Court, 673 P.2d 378, 380 (Colo.App.1983), to support his conclusion that Maestas created a procedural rule and corresponding remedy under C.R.C.P. 106. Close review of Zaharia compels the opposite conclusion. In Zaharia, the court of appeals considered a two-pronged challenge to a county court’s probable cause determination; first, whether any competent nonhearsay testimony was presented, and second, whether the county court abused its discretion in failing to allow the recall of a witness. Zaharia, 673 P.2d at 379-80. The court of appeals correctly explained that the district court could not review the county court’s probable cause finding. Id. However, the court concluded that the propriety of prohibiting the recall of a witness does not involve a factual determination and could properly be reviewed pursuant to a writ of prohibition under Rule 106. Id. at 380. While Zaharia allowed nonfaetually based procedural review, it expressly proscribed the review advocated by Abbott.
Here, the district court engaged in the review prohibited under White and Zaharia. The district court did not reverse based solely upon the People’s failure to present non-hearsay evidence. The court went beyond the procedural aspects of the county court proceedings to consider the substance of the preliminary hearing testimony. The court focused on the sexual contact element of the charge:
As I understand this case, one of the problems is that the victim had testified that the defendant had placed his hand on her buttocks, as I recall under the testimony, and whether that reached the elements even under the elements of the charge. *734Because I thought that the charge here involved some more private portion of the body. And for that reason, there may be a basic failure of the preliminary to show the elements, counsel, so that’s where the Court focused.6
The district court’s factual focus was also reflected in its warning to the prosecution that, if the charges were directly filed, the court would “hope you know more than what was shown in the transcript.” The question considered by the district court was whether the prosecution presented sufficient evidence to establish an element of the crime. The court’s recognition that no perceiving witness testified does not convert its review into a procedural ruling.
Abbott’s argument that the lack of non-hearsay evidence constituted a procedural failure illustrates the problem that could arise if we allowed district court review of a county court’s finding of probable cause. The temptation would exist to characterize insufficient evidence as a procedural deficiency.7 Contrary to Abbott’s contention, judicial efficiency would not increase, but we would add another layer of review in the preliminary stages of a criminal proceeding. A preliminary hearing would have the potential to be converted from a tool to screen bad cases, see, e.g., People v. Taylor, 655 P.2d 382 (Colo.1982), into a tool for delay. We have explained “[tjhis court generally discourages appeals involving sufficiency of the evidence determinations.” People v. Holder, 658 P.2d 870, 871 (Colo.1983). The rule applies equally to a finding of probable cause. Cf. People v. Hrapski, 658 P.2d 1367, 1368 (Colo.1983) (“This court generally discourages appeals involving probable cause determinations.”).
We do not believe the procedures for review of a probable cause determination previously announced and reaffirmed today do violence to our appellate rules. C.R.C.P. 106, like C.A.R. 21 is extraordinary in nature. See, e.g., Halaby, McCrea & Cross v. Hoffman, 831 P.2d 902 (Colo.1992). These rules should be construed together. Cf. Solliday v. District Court, 135 Colo. 489, 313 P.2d 1000 (1957). Review pursuant to C.R.C.P. 106(a)(4) is still available with respect to a preliminary hearing when a nonfactual procedural matter is challenged.8 C.A.R. 21 is available in those instances when factual findings are challenged. Both rules operate independently, but work together to provide sufficient relief from erroneous probable cause rulings. We will not stretch the limited scope of Rule 106 to allow factual determinations to be recast as procedural deficiencies.
Ill
We also granted review to consider whether the People should have sought review of the district court’s ruling in this court directly, rather than appealing to the court of appeals. Normally, the procedure for review when a district court acts in “excess of its jurisdiction” is to seek a writ of prohibition pursuant to C.A.R. 21. We have held, however, that an appeal from a writ of prohibition issued by the district court under C.R.C.P. 106 is not an appeal from a judgment in a criminal case, “but is a civil appeal even though it involves a question of criminal *735law.” Thomas v. District Court, 198 Colo. 87, 89, 596 P.2d 768, 770 (1979). Here, because the initial appeal was taken pursuant to a ruling under C.R.C.P. 106, the People’s appeal was appropriate.
Because we uphold the court of appeals’ ruling that the district court and the court of appeals may not properly review the county court’s finding of probable cause, we take this opportunity to clarify the procedures available to review a probable cause determination.
As discussed in Part II.A. supra, a defendant may seek review of a county court’s factual findings of probable cause in this court under C.A.R. 21.9 If the county court’s disputed ruling is strictly procedural, review by the district court is available under C.R.C.P. 106. Once the district court acts in a C.R.C.P. 106 proceeding, appeal to the court of appeals is proper. Similar limitations apply when the People appeal a finding of no probable cause. When the preliminary hearing is initially conducted in county court, the People’s only remedy for an erroneous finding of no probable cause is to seek permission to file a direct information in the district court pursuant to Crim.P. 5(a)(4)(V).10 E.g., Holmes v. District Court, 668 P.2d 11, 13 (Colo.1983) (“when the county court dismisses a felony complaint .. .■ the sole remedy available to the prosecution is requesting permission from the district court to file a direct information ... ”). When the district court makes a finding of no probable cause, or refuses to grant permission for a direct filing, the People may seek relief in the nature of a writ of prohibition under C.A.R. 21 to reinstate charges if the court acted without or in excess of its jurisdiction, or abused its discretion. Finally, the People have the option to appeal erroneous legal rulings under section 16-12-102(1) and C.A.R. 4(b)(2).11 We have previously reviewed trial courts’ application of legal standards under this section.12 These procedures provide the defendant and the prosecution alike adequate opportunity to seek relief from an erroneous finding of probable cause.
The judgment of the court of appeals is affirmed, and the cause is remanded for reinstatement of the charges.
. C.R.C.P. 106(a)(4) provides that a district court may review lower court rulings "[w]here any governmental body or officer or any lower judicial body exercising judicial ... functions has exceeded its jurisdiction or abused its discretion, and there is no plain, speedy and adequate remedy otherwise provided by law.” 7A • C.R.S. (1990).
. In Maestas we “admonish[ed] courts to beware of the excessive use of hearsay in the presentation of government cases,” explaining "[b]etter prosecutorial practice entails the presentation of a residuum of competent, non-hearsay evidence at the preliminary hearing to support probable cause.” Id. at 447, 541 P.2d at 892. We explained hearsay alone "should only be resorted to when the testimony of a perceiving witness is unavailable or when it is 'demonstrably inconvenient to summon witnesses able to testify to facts from personal knowledge.' ” Id. (quoting United States v. Umans, 368 F.2d 725 (2d Cir.1966)).
. Both People v. District Court, 652 P.2d 582 (Colo.1982), and People ex rel. Leidner v. District Court, 198 Colo. 204, 597 P.2d 1040 (1979) were reviewed by this court pursuant to C.A.R. 21. We have often been asked to review findings of probable cause pursuant to C.A.R. 21. See People ex rel. VanMeveren v. District Court, 195 Colo. 1, 4, 575 P.2d 405, 407 (1978) (original proceeding reinstating charges of sexual assault based on hearsay testimony of investigating officer "who *733had knowledge and information about many aspects of the alleged crime ... and who personally interviewed the defendant and witnesses whose statements he related”); D.H. v. People, 192 Colo. 542, 544, 561 P.2d 5, 6 (1977) (original proceeding from juvenile court explaining a transfer order from juvenile court to district court authorizing a person subject to juvenile delinquency proceedings to be tried as an adult resembles “bind-over from county court which may be reviewed by an original proceeding in cases where such review is deemed appropriate by this court” (internal citations omitted)); see also Blevins v. Tihonovich, 728 P.2d 732, 733 (Colo.1986) ("A defendant seeking to challenge an erroneous ruling on probable cause may seek extraordinary relief under C.A.R. 21.”).
. Abbott relies on a footnote in White where we indicated that a district court may review county court pretrial procedural decisions under an abuse of discretion standard. White, 713 P.2d 368 n. 4.
. Abbott relies on Maestas v. District Court, 189 Colo. 443, 541 P.2d 889 (1975) as the basis for the procedural rule. While Maestas provided trial courts with guidance regarding the admission of hearsay evidence, it allowed courts discretion to determine whether the prosecution had presented competent nonhearsay evidence to satisfy the "residuum” requirement, and whether the prosecution had established that a perceiving witness is "demonstrably unavailable.” Here, the county court found that the Maestas requirements were met:
First of all, this was not just a peripheral, extraneous witness that was offered to testify. This was the primary investigating officer who testified. It was clear that the officer conducted substantial interviews himself. Further the court finds that the People's case that was presented is not based wholly on hearsay. It is, and the Court recognizes that it is substantially hearsay, but that there was an on sight [sic] investigation of the scene of the alleged assault by the testifying witness. The court also finds that there were statements of the defendant who was a party and therefore, under the rules is not hearsay, putting the defendant at the time and place of the alleged assault.
A challenge to the quantity and sufficiency of nonhearsay evidence requires the reviewing court to go beyond the procedural ruling and to consider the factual findings of the trial court. We have consistently held such a review is not proper. See White v. MacFarlane, 713 P.2d 366 (Colo.1986); see discussion infra part II.A.
.Abbott's argument to the district court focused on the sufficiency of the evidence:
Judge, just as it is stated in our briefs, we don't feel like that meets the definitions. The statute is clear it has to be a sexual contact.... So we are not talking about touching the buttocks here, as the Court understands the testimony, which I believe is exactly what the testimony was. The statute is clear. There has to be a touching of either the anus, the perineum, the genitalia or the breast. And there was no evidence, whatsoever, at the preliminary hearing of any touching of any of those parts or any touching of the clothing covering the immediate area of any of those parts, (emphasis supplied).
. Abbott's third argument provides a clear example of this attempted recharacterization. He argues "[t]he failure to comply with the procedural rule regarding exclusive use of hearsay as a basis for a finding of probable cause resulted in a failure to establish the elements of the offense charged." Abbott engages in a contorted analysis of the testimony presented and concludes that a procedural defect occurred because "[t]he raw, unchallenged, unobserved statement of touch in this case [was] not sufficiently specific pursuant to C.R.S. § 18-3-401(4)."
. Rule 106 review is limited solely to procedural matters. See Enos v. District Court, 124 Colo. 335, 347, 238 P.2d 861, 868 (1951).
. Here, our review is limited to the issues before the court, both of which relate to the proper procedure for appeal of a county court’s finding of probable cause. This case is not properly postured for this court to review the county court's ruling under C.A.R. 21.
. Crim.P. 5(a)(4)(V) provides that "[d]ismissal of a felony complaint following a preliminary hearing or dismissal without 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.” Crim.P. 7(c)(2) provides for filing of a direct information when "[a] preliminary hearing was held in the county court and the accused person was discharged; ...” 7B C.R.S. (1984).
. Section 16-12-102(1) provides in part:
The prosecution may appeal any decision of the trial court in a criminal case upon any question of law.... The procedure to be followed in filing and prosecuting appeals under this section shall be as provided by applicable rule of the supreme court of Colorado. 8A C.R.S. (1994 Supp.).
C.A.R. 4(b)(2) provides:
Unless otherwise provided by statute or Colorado appellate rule, when an appeal by the state or the people is authorized by statute, the notice of appeal shall be filed in the Court of Appeals within forty-five days after the entry of judgment or order appealed from. The Court of Appeals, after consideration of said appeal, shall issue a written decision answering the issues in the case and shall not dismiss the appeal as without precedential value. The final decision of the Court of Appeals -is subject to petition for certiorari to the Supreme Court. 7B C.R.S. (1994 Supp.).
.Prior to 1988 People’s appeals were taken directly to this court. Under the present rule, the court of appeals considers People’s appeals based on erroneous legal rulings. See Crim.P. 4(b)(2); see also People v. Horn, 772 P.2d 108 (Colo.1989) (arresting officer’s testimony of conversations with defendant not hearsay under CRE 801(d)(2), and constituted sufficient non-hearsay evidence to reinstate charges); People v. Walker, 675 P.2d 304 (Colo.1984) (reversal based on trial court’s application of the improper legal standard of "proof beyond a reasonable doubt” at a preliminary hearing).
