The State petitions this court for a writ of mandamus directing Judge Ames to vacate two virtually identical pretrial discovery orders issued in State v. Mafi, wherein Defendant Mafi is charged, inter alia, with Driving Under the Influence of Intoxicating Liquor (DUI), pursuant to Hawaii Revised Statutes § 291-4. The government alleges “Judge Ames clearly abused his judicial discretion and exceeded his authority” under Rule 16(d) of *306the Hawaii Rules of Penal Procedure by permitting Mafi to discover 41 of 45 items he sought by means of a Written Request for Disclosure served on the State and a subsequent motion for discovery filed in district court. We agree that Judge Ames has acted beyond the scope of his jurisdiction pursuant to HRPP Rule 16 in this case and thus invoke our supervisory power over the district court to direct by mandamus that the two discovery orders entered by Judge Ames on September 1, 1988 be vacated.
I.
The extraordinary writ of mandamus is appropriate “to confine an inferior tribunal to the lawful exercise of its proper jurisdiction[.]” State v. Shintaku, 64 Haw. 307, 312, 640 P.2d 289, 293 (1982). See also In re Doe, 67 Haw. 466, 469, 691 P.2d 1163, 1165 (1984). But “mandamus may not be used to perform the office of an appeal.” State v. Shintaku, 64 Haw. at 310, 640 P.2d at 292 (citing Chambers v. Leavey, 60 Haw. 52, 57, 587 P.2d 807, 810 (1978)). Thus, we must at the outset determine whether the State may have a remedy by way of an appeal or any other means of relief from the disputed discovery orders.
“[T]he right of appeal in a criminal case is purely statutory and exists only when given by some constitutional or statutory provision.” State v. Oshiro, 69 Haw. 438, 441, 746 P.2d 568, 570 (1987). See also State v. Shintaku, 64 Haw. at 310, 640 P.2d at 292; State v. Johnson, 50 Haw. 525, 526, 445 P.2d 36, 37 (1968). HRS § 641-13 confers this right on the State in nine instances, which do not, however, include pretrial discovery orders.1 Thus, the State is without a remedy from the September 1,1988 discov*307ery orders issued by Judge Ames, unless this court grants its petition for extraordinary relief.
But “[t]he mere fact that other remedies are not available has never in itself been sufficient justification for mandamus.” State v. Shintaku, 64 Haw. at 311, 640 P.2d at 293 (citing In re Application of Liverpool, 14 Haw. 481, 488 (1902)). And “[w]here the trial judge has discretion to act,... mandamus clearly will not lie to interfere with or control the exercise of that discretion, even where the judge has acted erroneously,... unless ... the judge has exceeded his jurisdiction, has committed a flagrant and manifest abuse of discretion,... or has refused to act on a subject properly before the court where it was under a legal duty to act.” Id. at 312-13, 640 P.2d at 293-94. See, e.g., In re Doe, 67 Haw. 466, 691 P.2d 1163 (1984); State ex rel. Marsland v. Town, 66 Haw. 516, 668 P.2d 25 (1983).
*308Upon review of the instant petition, we are persuaded that Judge Ames “has exceeded his jurisdiction” by issuing the dual discovery orders in this case and that our intervention is necessary to correct persistent misapplication of HRPP Rule 16(d) in DUI cases heard in our district courts and to establish parameters of permissible discovery in misdemeanor DUI cases. We therefore invoke our supervisory jurisdiction over the district court by authority of HRS § 602-42 and exercise our discretionary power to issue a writ of mandamus pursuant to HRS § 602-5(4) and (7).3
II.
Disclosure in criminal cases is governed by HRPP Rule 16, which limits discovery “to cases in which the defendant is charged with a felony,” HRPP Rule 16(a), except as provided in HRPP Rule 16(d). HRPP Rule 16(d) reads:
*309Upon a showing of materiality and if the request is reasonable, the court in its discretion may require disclosure as provided for in this Rule 16 in cases other than those in which the defendant is charged with a felony, but not in cases involving violations.
Thus, discovery in a misdemeanor DUI case may be permitted by the trial judge “[u]pon a showing of materiality and if the request is reasonable,” but only to the extent authorized by HRPP Rule 16 for felony cases. HRPP Rule 16(b) enumerates the items the State must disclose upon request of a defendant who is charged with a felony. It provides in relevant part:
(1) Disclosure Upon Written Request of Matters Within Prosecutor’s Possession. Upon written request of defense counsel, the prosecutor shall disclose to him the following material and information within the prosecutor’s possession or control:
(i) the names and last known addresses of persons whom the prosecutor intends to call as witnesses, in the presentation of the evidence in chief, together with their relevant written or recorded statements, provided that statements recorded by the prosecutor shall not be subject to disclosure;
(ii) any written or-recorded statements and the substance of any oral statements made by the defendant, or made by a co-defendant if intended to be used in a joint trial, together with the names and last known addresses of persons who witnessed the making of such statements;
(iii) any reports or statements of experts, which were made in connection with the particular case or which the prosecutor intends to introduce, or which are material to the preparation of the defense and are specifically designated in writing by defense counsel, including results of physical or mental examinations and of scientific tests, experiments, or comparisons;
*310(iv) any books, papers, documents, photographs, or tangible objects which the prosecutor intends to introduce, or which were obtained from or which belong to the defendant, or which are material to the preparation of the defense and are specially designated in writing by defense counsel;
(v) any prior criminal record of the defendant.
(3) Disclosure of Matters Not Within Prosecution ’s Possession. Upon written request of defense counsel and specific designation by him of material or information which would be discoverable if in the possession or control of the prosecutor and which is in the possession or control of other governmental personnel, the prosecutor shall use diligent good faith efforts to cause such material or information to be made available to defense counsel; and if the prosecutor’s efforts are unsuccessful the court shall issue suitable subpoenas or orders to cause such material or information to be made available to defense counsel.
Mail’s Written Request for Disclosure, which was initially served on the State and subsequently considered by Judge Ames pursuant to a motion to compel discovery, sought 45 items from the prosecution. Judges Ames granted 41, denied three, and took no action with respect to one of the items requested.
We begin our review of Judge Ames’ orders of discovery by examining seven items that appear to fall within the ambit of HRPP Rule 16. Item 1 is a list of State’s witnesses, “together with their relevant written or recorded statements... [or] a written summary of the testimony each witness is expected to give at trial.”4 Item 2 consists of any “statements made by the Defendant together with *311the names and last known addresses of persons who witnessed the making of such statements.”5 Item 3 deals with “reports or statements of experts... including results of physical or mental examinations and of scientific tests, experiments, or comparisons.”6 Item 5 covers material “which the prosecution intends to present to the Court, or which were obtained from or which belong to the Defendant.”7 Item 6 is a request for “[a]ny prior criminal record of the Defendant or any State witness.”8 Item 30 concerns the results of the Intoxilyzer 401 IAS test taken by the defendant.9 Item 42 consists of information obtained by means of a horizontal gaze *312nystagmus test, if any, administered to the defendant.10 We believe these seven items would be discoverable in misdemeanor DUI cases, in whole or in part, within the limits prescribed by HRPP Rule 16(b), provided the defendant meets the threshold requisites of HRPP Rule 16(d). Thus, Judge Ames could have compelled the State to disclose the following material upon written request from Malí: Item 1, except for “a written summary of the testimony *313each witness is expected to give at trial,” which is not authorized by HRPP Rule 16(b)(l)(i); Items 2, 3, and 5 in their entirety, see HRPP Rule 16(b)(1)(h), (iii), and (iv), respectively; Items 30 and 42, limited to the results of the Intoxilyzer 401 IAS test and the horizontal gaze nystagmus test, if any, taken by defendant, see HRPP Rule 16(b)(l)(iii).
The government avers that it “routinely and freely supplie[s]” a defendant in a DUI case “the relevant waiver forms, Intoxilyzer and/or blood test results, operational checklists, witness statements, and maintenance logs.” Thus, we assume this material was disclosed to Mafi. If it was not, we believe Mafi is entitled to receive these items, even without submitting a Written Request for Disclosure or a motion to compel discovery.
But Mafi was neither entitled to nor was Judge Ames authorized to order disclosure of the additional 34 items on the list of requested materials. For not only is disclosure of these items not “provided for in .. . [HRPP] Rule 16,” which is a requirement of HRPP Rule 16(d), but too discovery in a misdemeanor case that exceeds the limits of discovery established by HRPP Rule 16 for felony cases cannot be justified under the rule.
Thus, we determine that Judge Ames acted beyond the scope of his authority under HRPP Rule 16(d) when he granted Mafi’s motion to compel discovery with respect to the following items:
4. Identification by title, journal, volume, page number, date and author of all documents (reports, forms, articles, journals, books, etc.) relied upon by the prosecution’s expert regarding his opinion of the reliability of the instrument used to determine Defendant’s blood-alcohol content.
