PER CURIAM.
Petitioner State of Hawai'i sought a writ of mandamus directing the trial judge (hereinafter “Respondent Judge”) in State v. Graham, Cr. No. 94-1048 (1st Cir. Haw. heard May 15, 1996) (granting motion to exclude testimony of state’s expert Vincent Di Maio or, in the alternative, to continue trial week), to (1) vacate his oral ruling [190]*190granting Defendant-Respondent Garreth A. Graham’s motion to exclude the testimony of the State’s proposed expert, Dr. Vincent Di Malo, and (2) grant an emergency stay of the proceedings in Graham’s criminal trial. On May 21,1996, we issued an order (1) requesting an answer or answers to the petition, as well as any supplemental memorandum or other supplemental materials that the State wished to file, and (2) staying the criminal proceedings pending review of the petition. After reviewing the memoranda and supplemental materials submitted by the parties,1 we granted the State’s petition on May 31, 1996, thereby vacating the Respondent Judge’s oral order and dissolving the temporary stay. Today’s opinion clarifies the trial court’s authority to strike a witness as a sanction for failing to comply with Hawaii Rules of Penal Procedure (HRPP) Rule 16.2
I. BACKGROUND
On May 17, 1994, Graham was indicted for the murder, attempted extortion, and kidnapping of Ming Li Chang, the wife of a Honolulu physician. Graham allegedly kidnapped Mrs. Chang on the morning of May 5, 1994, bound her eyes and mouth, and attempted to [191]*191induce Dr. Chang to pay $45,000.00 in ransom. After several continuances, Graham waived jury trial, and his trial was set to commence before the Respondent Judge on May 21,1996.
The only issue in the criminal case is whether Graham is guilty of murder or manslaughter. In his memorandum in opposition to the State’s petition, Graham acknowledges that he has already “confessed to manslaughter as well as kidnapping and attempted extortion.” It is undisputed that Mrs. Chang died of asphyxia, but the mechanism or means by which the asphyxia occurred is contested. The prosecution previously disclosed to the defendant its intention to call medical examiner Kanthi De Alwis, M.D., as an expert witness to testify that the cause of death was asphyxia by suffocation. Some time in 1995, the defense advised the deputy prosecuting attorney (DPA) that Terrance Allen, M.D., had been retained as an expert witness and that Dr. Allen would testify that Mrs. Chang died of positional asphyxia. However, in February 1996, the defense notified the DPA that John Hardman, M.D., had been retained to testify in place of Dr. Allen after the latter expert declined to testify. Defense counsel avers that he has repeatedly advised the DPA that Dr. Hardman would testify that there was insufficient data to determine the means or mechanism of Mrs. Chang’s death — i.e., the cause of death’could have been either suffocation, positional asphyxia, “fright,” or congestive heart failure. However, the DPA contends that 1) defense counsel merely informed him, during their initial conversations, that Dr. Hardman had been retained and would be rendering a report, a copy of which would be provided to the prosecution, and 2) approximately two weeks prior to the May 15 hearing on Graham’s motion to exclude Dr. Di Maio’s expert testimony, defense counsel stated that Dr. Hardman believed that congestive heart failure was the cause of death.3
Between February and April 1996, defense counsel made repeated, but unsuccessful, requests of Dr. Hardman for the report he had “promised.” Sometime in April 1996, Dr. Hardman faxed a document to defense counsel, which the latter described as a “totally useless document” containing “some thoughts without any conclusions ... [or] findings[.]” According to the DPA, Dr. Hardman or his secretary informed him that the document was destroyed in accordance with defense counsel’s instructions. Defense counsel avers that Dr. Hardman told him to throw the document away. In any event, the document was never disclosed to the DPA, and he did not learn of it until May 14, 1996, when Dr. Hardman’s secretary returned one of the DPA’s telephone calls.4
The DPA avers that, between February and April 1996, he consulted with Dr. De Alwis regarding the defense’s likely position [192]*192at trial — viz., initially, that the cause of Mrs. Chang’s death was positional asphyxia rather than asphyxia by suffocation, and later, that congestive heart failure was the cause. After defense counsel informed the DPA that Dr. Hardman believed that Dr. De Alwis’s conclusion of death by suffocation was without support in the autopsy, Dr. De Alwis recommended that the DPA request Dr. Di Maio’s assistance. On April 24, 1996, the DPA requested early designation of a trial judge “to resolve pretrial matters ... [including] evidentiary matters such as the admissibility of ... expert medical testimony[,] ... [which would] facilitate the scheduling of ... expert witnesses for trial.”
By fax letter dated April 29, 1996, Dr. Di Maio affirmatively responded to the DPA’s April 17, 1996 letter of inquiry. See supra note 3. One week later, on May 6,1996, the DPA obtained authorization for payment of expert witness consultation fees. A mere four days after that, during a scheduled pretrial conference on May 10, 1996, the DPA announced his intention to call Dr. Di Maio as an expert witness. Defense counsel objected and filed a motion to exclude Di Maio’s testimony or to continue the trial. During a hearing held on May 15, 1996, defense counsel asserted that allowing Dr. Di Maio to testify would substantially delay the trial,5 that the indigent defendant would have to apply for court approval to hire a similarly prominent expert for rebuttal, and that the DPA had offered no meaningful explanation for failing to retain Dr. Di Maio until ten days before trial.
The court subsequently stated:
In the area of experts, unfortunately, Rule 16 of the [HRPP] does not pattern the [Hawaii] Rules of Civil Procedure; and there’s no requirement for an expert to disclose in writing the expert’s opinions, as well as the bases of the opinions.
But apparently from this record, Dr. Hardman represented to defense counsel that the unwritten report was forthcoming and defense counsel so represented to the prosecution. And at this stage, we don’t have a written report.
The Court believes that at some point, the prosecution should have realized that it was not going to have a report or one would not be forthcoming in a timely manner. And the prosecution at that point I believe should have attempted to contact Dr. Hardman to elicit opinions from the doctor on the bases for those opinions even though not in written form. That the prosecution failed to do so in this case.
Now, these are the options that this Court has. I can continue the trial. We’ve been waiting two years to go to trial. I don’t think that’s a viable option.
I can deny this motion without prejudice, direct that Dr. Hardman submit a written report by a certain date and direct that Dr. Di Maio also submit a written report by a certain date. And after I’ve heard the testimony, determine whether or not it’s necessary for the Court to hear anymore....

The third I can just deny this motion. But if I at some point decide to let Dr. Di Maio testify, submit his written findings, then I’m going to have to give defense a brief continuance to get a surrebuttal expert.
[[Image here]]
As [a] jury waive[d trial], it’s easier to manage. But anyway those are the op[193]*193tions. Right now my inclination is just to grant the motion.
[[Image here]]
... Di Maio is merely going to corroborate the testimony of the medical examiner, and it’s just cumulative.[6]
[[Image here]]
Both attorneys are in difficult positions because you’re dealing with experts, and at this point we’re just speculating because we don’t have anything in writing from either Di Maio and Hardman. All we have is oral statements.
But, anyway, I’m going to deny the — I’m going to grant the motion for the following reasons:
One, failure of the prosecution to attempt to interview Dr. Hardman earlier to elicit an opinion and the bases for the opinion.
And, secondly, failure to file a motion to compel disclosure in writing of any opinions and any bases of the opinions.
I balance that against any legal prejudice from the prosecution. And as counsel have argued the ease to this Court, the issue is very simple. Was there a knowing cause of death? And I guess the subsidiary issue would be the cause of death. But the medical examiner qualifies as an expert so the State has one expert, the defense has one expert. And under these circumstances, I don’t think any further delays would be justified. It’s for those reasons I’ll grant the motion.

II. STANDARD OF REVIEW
A writ of mandamus is an extraordinary remedy that will not issue unless the petitioner demonstrates: (1) a clear and indisputable right to relief; and (2) a lack of other means to adequately redress the alleged wrong or obtain the requested action. Such writs are not meant to supersede the legal discretionary authority of the lower courts, nor are they meant to serve as legal remedies in lieu of normal appellate procedures. Where a trial court has discretion to act, mandamus clearly will not lie to interfere with or control the exercise of that discretion, even when the judge has acted erroneously, unless the judge has exceeded his or her jurisdiction, has committed a flagrant and manifest abuse of discretion, or has refused to act on a subject properly before the court in which it is subject to a legal duty to act.
Straub Clinic & Hospital v. Kochi, 81 Hawai'i 410, 414, 917 P.2d 1284, 1288 (1996) (citations omitted).
III. DISCUSSION
The State contends that the trial court did not make a finding that HRPP Rule 16 had been violated or that Graham suffered any prejudice as a result of being given the name of the State’s expert witness only ten days before the scheduled week of trial. In the alternative, the State argues that the trial court abused its discretion by arbitrarily disregarding the less drastic sanction of granting a continuance rather than excluding the expert testimony. Graham replies that mandamus is not available to review discretionary decisions of the trial courts.
On the record before us, Graham’s position is untenable for at least three reasons. First, Graham’s contention is correct only insofar as this court has questioned the precise extent to which the “flagrant and manifest abuse of discretion” exception applies to mandamus proceedings. See Akana v. Da[194]*194mon, 42 Haw. 415 (1958), cited in State ex rel. Marsland v. Shintaku, 64 Haw. 307, 312 n. 8, 640 P.2d 289, 293 n. 8 (1982).
The precise extent of this exception as articulated in Fong v. Sapienza[, 39 Haw. 79, 81 (1951),] was first brought into question in ... [Alcana ], which criticized the Fong court for its ruling as based on a quotation taken out of context in a former case. The majority in Fong, faced with the question whether mandamus would lie to compel an inferior court to exercise its discretion in a particular way, ruled that mandamus could be so issued where such discretion had been abused, based on a quotation from In re Application of Ivers, 12 Haw. 99 (1899), which ended as follows: “[Mandamus] does not lie to control judicial discretion, except when that discretion has been abused.” Id. at 103, quoting Virginia v. Rives, 100 U.S. 313, 323 [25 L.Ed. 667] (1879). The Alcana court, questioning this departure from the general rule of non-interference by way of mandamus where the judge has discretion, noted as had the lone dissenter in Fong that the quotation from Virginia should have been completed as follows: “... but it is a remedy when the case is outside the exercise of this discretion, and outside of the jurisdiction of the court or officer to which or to whom the writ is addressed.” Virginia v. Rives, id. at 323-24. It did not rule on the extent of Fong’s applicability in light of the completed quotation, however, as it found no abuse of discretion.
In Brown v. Hawkins, 50 Haw. 232, 437 P.2d 97 (1968:), the court saw no need to accept Fong as controlling, finding no abuse of discretion in the case before it. It therefore adhered to the rule of Territory ex rel. Scott v. Stuart, 22 Haw. 576 (1915), that mandamus will not lie to enter a particular judgment or to set aside a decision already made. We similarly need not rule on the extent of Fong ’s applicability for the reasons set forth herein.
Shintaku, 64 Haw. at 312 n. 8, 640 P.2d at 293 n. 8. The Shintaku court expressed the following rationale for its decision to deny a writ of mandamus in that case:
In granting the. motion for judgment of acquittal in the ... [proceedings below], Judge Shintaku acted fully within his prescribed powers as described in [HRPP Rule] 29(c). And while the State has raised serious questions about the correctness of the judge’s decision, we cannot say that the State’s petition on its face makes a “clear and indisputable” case of a flagrant and manifest abuse of discretion on Judge Shintaku’s part. That being the case, the court is powerless to issue an extraordinary writ or to otherwise further review the merits of the State’s petition.
We are mindful of our supervisory role over the courts of inferior jurisdiction “to prevent and correct errors and abuses therein where no other remedy is expressly provided by law.” HRS § 602-4 (1976 & Supp.1981). Such power, as is that to grant extraordinary relief generally, has been exercised by this court in rare and exigent circumstances. See Gannett Pacific Corp. v. Richardson, 59 Haw. 224, 580 P.2d 49 (1978). For the reasons expressed above, however, we are compelled by the particular facts of the case to refrain from issuing mandamus in the exercise of that supervisory jurisdiction.
Id. at 313, 640 P.2d at 294 (footnote omitted).7
On at least four occasions, this court has granted the extraordinary writ of mandamus where a trial judge has misapplied the law. See, e.g., Pelekai v. White, 75 Haw. 357, 362-68, 861 P.2d 1205, 1208-11 (1993) (vacating trial judge’s order setting bad in reliance upon an inflexible “bail schedule,” promulgated by the senior judge, which unlawfully divested the trial court of the discretion accorded the bail-setting authority by HRS § 804-9 (1993)); State ex rel. Marsland v. Ames, 71 Haw. 304, 308, 788 P.2d 1281, 1283-84 (1990) (granting writ of mandamus where trial judge misapplied HRPP Rule 16(d) to misdemeanor case of driving under the influence); In re Doe, born 9/22/65, 67 Haw. 466, [195]*195469, 691 P.2d 1163, 1165 (1984) (reversing family court’s sua sponte dismissal of the prosecution’s petition for waiver of jurisdiction over a minor under HRS § 571-22(c) (Supp.1983), and issuing a writ of mandamus directing the family court to hold a hearing on the petition so that the prosecution would have the opportunity to demonstrate that the statutory preconditions had been satisfied); State ex rel. Marsland v. Town, 66 Haw. 516, 526-27, 668 P.2d 25, 31-32 (1983) (granting writ of mandamus where family court failed to comply with HRS § 571-22 concerning the waiver of jurisdiction over a minor); cf. In re Tactacan, 42 Haw. 141, 142-43 (1957) (refusing to grant writ of mandamus notwithstanding trial judge’s apparently erroneous denial of plaintiffs unopposed motion to consolidate five eases involving the same property, see Revised Laws of Hawaii § 193-45 (1955), because plaintiff would have an adequate remedy by way of an appeal).
Second, a writ of mandamus is appropriate in the instant ease because there is no other means available to adequately redress the alleged wrong or obtain the requested action, and the prosecution has demonstrated a clear and indisputable right to relief.
The trial court faulted the prosecution for failing to 1) attempt to contact Dr. Hardman sooner than it did for the purpose of eliciting his opinions in unwritten form and 2) file a motion to compel disclosure in writing of Dr. Hardman’s opinions and any bases for those opinions.8 However, the court’s implicit finding that the DPA did not fully comprehend the nature of Dr. Hardman’s testimony until very late in the process exonerates the prosecution. In other words, the court did not impose sanctions on the prosecution for fail-mg to comply with its obligation under HRPP Rule 16(e)(2) to “promptly disclose” additional information — viz., the name of a new expert witness that the DPA planned to call during presentation of its evidence in chief, see HRPP Rule 16(b)(l)(i) — obtained subsequent to the DPA’s compliance with initial discovery requirements. Rather, the court essentially sanctioned the prosecution because it “should have realized that it was not going to have a report [from Dr. Hard-man] or one would not be forthcoming in a timely manner.” (Emphasis added.) Although HRPP Rule 16(e)(9)(i) provides the court with discretion to enter orders that it “deems just under the circumstances” when “a party has failed to comply with this rule[,]” the court in the instant case precluded the prosecution’s expert witness from testifying during its case in chief because the prosecution did not promptly determine the need for an additional expert witness. Nevertheless, HRPP Rule 16(b)(l)(i) does not obligate the prosecution to disclose the name and address of, or statements made by, any person, unless and until the prosecution intends to call that person as a witness in the presentation of the evidence in chief.9 When that decision is made, the prosecution must “promptly disclose” the appropriate information to the defense.
We observe that there is no indication in the record that the DPA willfully or negligently “withheld” any material information from the defense.10 Rather, close inspection of the record reveals that the DPA acted in good faith and with civility by attempting to work out discovery issues with defense counsel before seeking to invoke the court’s authority. The trial court implicitly recognized [196]*196that the DPA had relied on defense counsel’s assurances that Dr. Hardman was working on a report; however, we observe that defense counsel destroyed the only document prepared by Dr. Hardman to date, as far as we can tell from the record,11 without even mentioning having done so to the DPA. Without a report of the defense expert’s opinion, the prosecution’s ability to prepare for trial was severely impaired. Cf. Lee v. Elbaum, 77 Hawai'i 446, 454, 887 P.2d 656, 664 (App.1993), cert. granted, 74 Haw. 651, 853 P.2d 542, cert. denied, 77 Hawai'i 489, 889 P.2d 66 (1995); Swink v. Cooper, 77 Hawai'i 209, 881 P.2d 1277 (App.1994) (affirming the exclusion of additional expert testimony, which was offered at trial in violation of the continuing duty to supplement prior discovery responses).12 Nevertheless, without the benefit of such a report and based only on his understanding of Dr. Hardman’s opinion as conveyed by defense counsel, the DPA continued his efforts to prepare for trial. He consulted with Dr. De Alwis regarding Dr. Hardman’s presumed testimony between February and April 1996.
Although the DPA first contacted Dr. Di Maio about the possibility of assisting the prosecution at trial in mid-April 1996, the doctor did not respond until April 29, 1996. On May 6, 1996, the DPA transmitted relevant materials to Dr. Di Maio, by express mail, for him to review. The DPA did not retain Dr. Di Maio until, at the earliest, four days before announcing his intent to call him as an expert witness. It cannot reasonably be said that the DPA’s revelation during the pretrial conference amounted to a failure to promptly disclose Dr. Di Maio to the defense. The record does not reveal that the court issued a pretrial order setting a cut off date for naming expert witnesses. Nor was there any impediment preventing the court from exercising its inherent powers by issuing an order setting discovery cut off dates and/or deadlines for the final naming of witnesses patterned after Rule 12 of the Rules of the Circuit Courts of Hawaii (RCCH). See RCCH Rules 12{l), 12(m), and 12(r). Moreover, any argument that the DPA neglected to comply with HRPP Rule 16 must fail because the HRAP contain no requirement that discovery must be performed by a certain date prior to trial.13 In fact, HRPP Rule 16(e)(2) contemplates lawful disclosure during trial when a party discovers any additional material or information.14 All that is [197]*197required under the rule is prompt disclosure once the additional material or information is obtained.
Third, and finally, to the extent that the trial court may have been exercising its inherent power to administer justice by imposing sanctions as a remedy for perceived prejudice to the defendant, see Richardson v. Sport Shinko, 76 Hawai'i 494, 507-08, 880 P.2d 169, 182-83 (1994), rather than relying on HRPP Rule 16(e)(9)(i), we review its ruling for abuse of discretion. Id. (citing Kukui Nuts of Hawaii, Inc. v. R. Baird & Co., 6 Haw.App. 431, 438, 726 P.2d 268, 272 (1986)). As discussed earlier, the trial court implicitly found that the DPA had not willfully failed to disclose Dr. Di Maio at an earlier time. Based on the record before us, we cannot conclude that the DPA’s failure to determine the need for Dr. Di Maio’s testimony sooner was negligent. In any event, we reject Graham’s allegation that he was severely prejudiced by the disclosure of Dr. Di Maio as an expert witness less than two weeks before the date set for trial. The jury-waived trial had not yet begun, and the prosecution was amenable to a continuance. Moreover, Dr. Di Maio was not being offered to support a new theory concerning the cause of death, but merely to shore up perceived gaps in Dr. De Alwis’s testimony based upon evidence that had already been disclosed to the defense.
Thus, under the circumstances presented in this case, we hold that the trial court’s exclusion of the State’s expert witness amounted to a flagrant and manifest abuse of discretion.
IV. CONCLUSION
Based on the foregoing analysis, we granted the State’s writ of mandamus on May 31, 1996 and, thereby, vacated the trial court’s oral order excluding the State’s expert witness from testifying and dissolved the temporary stay.
