OPINION OF THE COURT BY
Pratikshya Gurung1 was born with brain damage and quadriplegia, among other conditions, resulting in the filing in the circuit court of a medical negligence action against Norton Hospital. This case is before us on appeal from the Court of Appeals’ dismissal as moot of a writ action filed by Norton over a discovery dispute with the Estate. We reverse the dismissal and remand to the Court of Appeals for further review.
During the course of routine discovery, the Estate requested production from Norton of various hospital documents relating to patient safety — documents Norton is required by law to create and maintain. These documents involve the post-occurrence review and peer-review process. Norton argued the documents were protected under federal law.2 The Estate sought and received from the trial court an order compelling Norton to produce the documents. Consistent with our recent decision in Tibbs v. Bunnell,3 the trial court conducted an in-camera review of the documents and determined they were not privileged.
While the parties were litigating over whether the patient-safety documents were discoverable, other discovery proceeded. The trial court’s order compelling the production of the disputed documents and denying Norton’s'privilege claim was entered August 31, 2015. A nurse who treated Gurung during her time at Norton was scheduled to be deposed on September 2. On September 1, Norton filed in the Court of Appeals a petition for a writ of prohibition as well as a request for emergency relief, ie., an order staying execution of the trial court’s discovery order. Norton notified the Estate and the trial court of this filing with the Court of Appeals.
In response to Norton’s maneuvers, the Estate sought and received an emergency hearing with the trial court on September 1. The primary — if not sole — purpose of *845the hearing was to determine if the nurse’s deposition scheduled for the following day could proceed as scheduled. The Estate made clear that the deposition had been scheduled for months and any further delay would be lengthy because the nurse was pregnant and nearing her delivery date. The Estate argued that even though it wanted to use the disputed documents at the nurse’s deposition it mostly wanted the deposition to proceed with or without the disputed documents.
Norton was unable to get a hearing on its emergency motion in the Court of Appeals before the Estate’s emergency hearing with the trial court. After hearing arguments, the trial court ruled that the nurse’s deposition should proceed as scheduled and the disputed documents should be provided to the Estate. The trial court then literally took matters into its own hands and handed the copies of the disputed documents Norton had submitted for in-camera review directly to counsel for the Estate, in open court and on the record.
The Court of Appeals later dismissed Norton’s writ petition as moot “because the issue Norton raised [was] resolved below, and because [the] Court [could not] grant meaningful relief to either party.” Norton appeals that decision to this Court as a matter of right.4
At the outset, yve should be clear about the issue Norton now places before us. Norton, of course, sought a writ in the Court of Appeals. A writ is an extraordinary use of our- discretionary authority— one that we are “cautious and conservative both in entertaining petitions for and in granting such relief.”5 Obviously the Court of Appeals’ decision is appealable to this Court, but in this particular case, while a party is appealing from an adverse ruling on its writ petition, we have a wholly insufficient record to review. And Norton does not request a writ of prohibition .from this Court. So our review of the Court of Appeals’ decision is not through the lens of our writ jurisprudence.
A case becomes moot when a rendered judgment “cannot have any practical legal effect upon a then existing controversy.”6 And “[t]he general rule is, and has long been, that where, pending an appeal, an event occurs which makes a determination of the question unnecessary or which would render the judgment that might be pronounced ineffectual, the appeal should be dismissed.”7 This is essentially what the Court of Appeals did below. Were we to rule that the Court of Appeals was erroneous, it is arguable whether or not we can afford meaningful relief. We have repeatedly recognized that allegedly privileged information, once disclosed,-cannot be rendered undisclosed. On its face, the trial court’s decision to hand-deliver the disputed documents to the Estate’s counsel perhaps did render this action moot.
*846. The "problem with this somewhat simplistic view of the instant circumstances lies with the bedrock principle that a privilege is personal and can only be waived by the party claiming , the privilege. -To the .contrary, the'trial court, in essence, waived Norton’s claim of privilege by. literally providing the Estate with the documents claimed to be privileged.8 The trial court’s act does not resolve any legal issue — in fact, it creates more questions than answers. A live legal controversy existed when Norton sought relief in the Court of Appeals. For us to hold otherwise would be to dilute the role of privilege in the discovery process and wrest control of the privilege from the party asserting its application.
To our knowledge, we have never dealt with similar conduct by a trial court. We appreciate the special circumstances confronting the trial court9 and the trial court’s attempt to act promptly and equitably. But it is important to emphasize that the trial courts are “not in the document delivery business; instead, they, are in the business of ruling on document delivery motions.”10 The responsibility to produce documents lies with the parties and the parties alone. It is problematic for. trial courts to surrender control of the documents in this manner for a couple of reasons.
First of all, it.raises unnecessary questions, about the record.' By handing over the documents that were produced for in-camera review, the trial court created a , gap in the record. Here, the trial court recognized , this and. asked the Estate’s counsel -to make copies of the documents and return the original versions to the, trial court. This is simply not good practice — a trial court should demand, that the parties produce documents to one another .because this keeps the record intact while preserving a party’s right to refuse production or face appropriate consequential sanctions.
Second, and most importantly, the trial court’s production of the documents in conjunction with the Court of Appeals’ decision effectively precludes a party from challenging a trial court’s privilege ruling. A trial court’s ruling on an asserted privilege should not be insulated from review. A question of privilege is of critical importance — so much so that we have recognized routinely that it is worthy of our writ authority. In fact, privilege rulings are virtually the only circumstances we have recognized worthy of our “certain special cases exception” because a “substantial miscarriage of justice will result if the lower court is proceeding erroneously, and correction of the error is necessary' and appropriate in the interest of orderly judicial administration.”11
*847The merit, or lack thereof, of Norton’s privilege argument' is secondary in the context of the potential damage the lower courts’ ruling could work on our system of justice. Best practice dictates that when a trial court “conducts in-camera review of documents,, determines that production is appropriate and so orders, it should, as a matter of course, provide the [party] who submitted the documents for in-camera review an opportunity to comply with the court’s order or stand in contempt.” 12
Our holding today should not be read to say that a trial court cedes jurisdiction when a party files a writ petition challenging a privilege ruling — far from it. A trial court retains jurisdiction over the case and its discovery methodology despite a pending writ. But a trial court must respect the writ process and the party’s right to proceed in that manner. Discovery in this case did not' have to stop because of Norton’s writ petition. In fact, the Estate requested the . trial court compel the nurse’s deposition to proceed even without the challenged documents. This was permissible. The trial court simply cannot participate itself in discovery and produce documents that a party alleges are privileged in the face of a writ challenging the trial court’s determination that they aré not privileged.
No doubt a live legal .controversy has existed throughout the instant proceedings; yet, this all begs the question: even in the face of a live legal controversy, what remedy could the Court of Appeals have provided Norton? Most case law in this area stems.from allegedly privileged material seized unlawfully through, for example, an unconstitutional search.13 In those situations, courts have récognized that either returning the challenged documents or suppressing evidence obtained from those documents, or both, is appropriate.14 We acknowledge that the case law does not dovetail precisely with the instant situation — the differences in criminal and civil proceedings being what they are — but we see little reason not to recognize these available options in the' rare circumstances presented here. In the end, “[o]nce the information is furnished it cannot be recalled”15; but, these remedies provide some measure of recourse where the trial court' erroneously waived a party’s privilege by disclosing the documents in issue. This does not alter our case law holding that a party seeking a writ from an order compelling discovery does not have an adequate remedy by appeal. That remains true. Our decision today should be limited to the unique circumstances presented.
The Court of Appeals abused its discretion because its decision was not based on sound legal principles.16 Norton’s writ ac*848tion is not moot because relief can' still be afforded. It is true that the documents Norton alleges are privileged have now-been provided to the Estate, but options remain. We remand the matter to the Court of Appeals for consideration of Norton’s asserted privilege in light of our decision in Tibbs v. Bunnell.
All sitting. All concur.
