Question 1
Officer Ramos moved for summary judgment in Simone's 42 U.S.C. §1983 suit, asserting qualified immunity. The district court denied the motion, stating: 'Viewing the record in the light most favorable to Simone, there is a genuine dispute of material fact whether Officer Ramos used excessive force. Because that factual dispute must be resolved before the qualified-immunity question can be decided, summary judgment is denied.' Officer Ramos wants to appeal now, before trial.
In Ostrander v. Gregg, the court of appeals held: 'An interlocutory order is immediately appealable under the collateral-order doctrine only if it conclusively determines the disputed question, resolves an important issue completely separate from the merits, and is effectively unreviewable on appeal from a final judgment. A denial of qualified immunity is immediately appealable when it turns solely on a question of law. A denial of qualified immunity is not immediately appealable, however, insofar as it rests on a determination that a genuine dispute of material fact exists for trial.'
Which of the following statements best describes whether Officer Ramos may immediately appeal the district court's denial of summary judgment?
- Yes, because a denial of qualified immunity is a collateral order: it conclusively determines an important issue separate from the merits and would be lost if review were deferred until after trial.
- No, because the denial is based on a factual dispute, and the collateral-order doctrine does not permit immediate review of such fact-based qualified-immunity denials. (correct answer)
- Yes, because the legal question whether the force was clearly excessive may be decided by the court of appeals from the existing record, irrespective of the district court's factual dispute finding.
- No, because a denial of summary judgment is an interlocutory order; qualified immunity does not create an exception to the final-judgment rule, so Officer Ramos must wait until after trial to appeal.
Explanation: Whenever you see a denial of qualified immunity on appeal, immediately ask why it was denied. The collateral-order doctrine allows an immediate appeal of a QI denial only when it turns on a pure question of law—for example, whether the plaintiff's alleged facts, taken as true, violate clearly established law. But if the denial rests on the district court's finding that a genuine dispute of material fact exists about what actually happened, the appellate court lacks jurisdiction to hear it now. Here, the district court expressly stated that the denial hinges on a genuine dispute of material fact over excessive force, and that this dispute must be resolved before the QI question can be decided. Under the rule in Ostrander, that fact-based denial is not immediately appealable. Officer Ramos must wait until after trial to challenge the QI ruling on final judgment.
Now examine the distractors. The choice claiming "a denial of qualified immunity is a collateral order" that is immediately appealable overstates the rule; the collateral-order exception is narrow and only applies to purely legal denials. The choice suggesting the appellate court can decide the legal question of whether the force was clearly excessive from the existing record ignores that the factual dispute is the very reason for the denial—the appellate court cannot resolve that disputed fact on interlocutory review. Finally, the choice stating "qualified immunity does not create an exception to the final-judgment rule" is wrong, because QI does create an exception for legal questions, just not for factual disputes. Remember the trap: if the order says "genuine dispute of material fact," you cannot appeal now; if it says "taking facts as true, no clearly established right," you can.
Question 2
A plaintiff sued a county and a sheriff's deputy in federal court, alleging that the deputy used excessive force in violation of the Fourth Amendment. The deputy moved for summary judgment, arguing he was shielded from suit because his conduct did not violate clearly established law. The district court denied the motion, explaining: 'Viewing the evidence in the light most favorable to the plaintiff, a reasonable jury could find that the deputy's use of force was objectively unreasonable, and the right was clearly established at the time.' The deputy wants to appeal that ruling immediately, before trial.
Which of the following best describes the availability of immediate appellate review?
- The denial is immediately appealable in its entirety because an immunity defense is an immunity from suit, not merely a defense to liability on the merits.
- The denial is immediately appealable under §1292(a)(1), because an order denying immunity operates as an injunction against requiring the defendant to stand trial.
- The denial is not immediately appealable because an immunity defense, like other affirmative defenses, may be reviewed only after trial.
- The denial is immediately appealable only to the extent it presents a purely legal issue; to the extent it depends on a disputed factual issue, appellate review must await final judgment. (correct answer)
Explanation: Denials of qualified immunity are immediately appealable under the collateral order doctrine only to the extent they present purely legal issues. When the denial rests on a genuine dispute of material fact, the appellate court generally lacks jurisdiction over that factual component until final judgment. Here the district court expressly relied on viewing the evidence in the plaintiff's favor and concluding that a jury could find the use of force objectively unreasonable; the order is therefore not immediately appealable in its entirety. A overstates the general immunity rationale and misses the factual-dispute problem. B is wrong because §1292(a)(1) applies to injunctions, not immunity rulings. C is wrong because some immunity denials can be immediately appealed when they turn on legal questions.
Question 3
Stratton sued Doral Corp. Doral moved to dismiss for lack of personal jurisdiction. The district court denied the motion. In its order, the court stated:
'This order involves a controlling question of law as to which there is substantial ground for difference of opinion—whether Doral's contacts with this forum satisfy due process. An immediate appeal from this order may materially advance the ultimate termination of this litigation.' The court did not otherwise certify the order under any other rule. Fourteen days after the order was entered, Doral filed a notice of appeal with the court of appeals, but did not file an application for permission to appeal or otherwise seek permission to appeal.
The Interlocutory Appeals Act, Section 315(a), provides:
'When a district judge, in making in a civil action an order not otherwise appealable under this section, shall be of the opinion that such order involves a controlling question of law as to which there is substantial ground for difference of opinion and that an immediate appeal from the order may materially advance the ultimate termination of the litigation, he shall so state in writing in such order. The court of appeals may thereupon, in its discretion, permit an appeal to be taken from such order, if application is made to it within ten days after the entry of such order.'
Does the court of appeals have jurisdiction over Doral's appeal?
- Yes, because the district court's written certification satisfied Section 315(a), and once certified, an interlocutory order is immediately appealable as of right.
- Yes, because an order denying a motion to dismiss for lack of personal jurisdiction is immediately appealable under the collateral-order doctrine, since the defendant has a right not to be haled into court.
- No, because Doral did not timely file an application for permission to appeal, and the court of appeals may permit such an appeal only in its discretion. (correct answer)
- No, because an order denying a motion to dismiss for lack of personal jurisdiction is never appealable before final judgment, regardless of whether the district court certifies it.
Explanation: Whenever you see an interlocutory appeal question, immediately think of the strict statutory gatekeeping rules—appeals before final judgment are the exception, not the right. Here, the district court properly certified the order under Section 315(a), which is the first step. However, that certification alone is meaningless without the second step: the party must file a timely application for permission to appeal with the court of appeals, and the court of appeals must then exercise its discretion to grant that permission. Doral filed a notice of appeal fourteen days after the order, which is both the wrong procedural vehicle and untimely (the statute requires an application within ten days). Because Doral never filed an application, the court of appeals has no jurisdiction.
The answer stating that certification makes the order "appealable as of right" is wrong because Section 315(a) explicitly says the court of appeals "may thereupon, in its discretion, permit an appeal"—it is never a matter of right. The collateral-order doctrine answer is also incorrect: denial of a motion to dismiss for lack of personal jurisdiction is not immediately appealable under that doctrine because it is reviewable on appeal from a final judgment (the right not to be haled into court is protected by the ability to raise the defense later). Finally, the answer claiming such orders are "never appealable before final judgment" is too absolute—they are appealable if the Section 315(a) requirements are met. The core trap is confusing the district court's certification with the appellate court's permission. Remember the two-step gate: certification from the trial court plus a timely petition and grant from the appellate court.
Question 4
A consumer filed a putative class action against a bank in federal court, asserting statutory and common-law claims. The district court certified a class on the statutory claim but declined to certify the class on the common-law claim. The bank believes the certification decision is erroneous and wants appellate review before litigating a large class. The judge has made no partial final judgment determination, and no injunction is in the case.
Which of the following is the bank's most promising avenue for immediate review?
- An interlocutory appeal as of right under §1292(a)(1), because the certification order determines the scope of any injunctive relief that may ultimately be awarded.
- A petition for permission to appeal the class-certification order under Rule 23(f), filed within the time prescribed by that rule. (correct answer)
- A petition for a writ of mandamus, because continuing with the class action would impose irreparable litigation burdens on the bank.
- No immediate review is available; the bank must raise its objection to certification in an appeal from a final judgment on the merits.
Explanation: Rule 23(f) provides a discretionary mechanism for appellate review of an order granting or denying class certification. Because the certification order is interlocutory and not otherwise appealable, the bank must seek permission from the court of appeals, not appeal as of right. A is wrong because no injunctive relief is at issue and certification does not become appealable simply because it might affect future remedies. C is wrong because mandamus requires extraordinary circumstances, not merely substantial litigation burdens or alleged error. D is wrong because Rule 23(f) specifically authorizes review of class-certification orders before final judgment.
Question 5
During discovery in a federal antitrust action, the defendant moved to quash a subpoena served on its in-house counsel, asserting attorney-client privilege. The district court denied the motion and ordered production of the documents before trial. The court declined to certify the order for interlocutory appeal. The defendant wants immediate review, arguing that disclosure will destroy the privilege and any later appeal cannot undo that harm.
Which of the following is the most accurate statement about the defendant's appellate options?
- The order is immediately appealable under the collateral order doctrine because it conclusively determines the privilege issue and disclosure would make later appellate review ineffective.
- The order is not immediately appealable, but the defendant may seek a writ of mandamus if it can show the privilege ruling was clearly erroneous and that no adequate alternative remedy exists. (correct answer)
- The order is immediately appealable under §1292(a)(1), because an order compelling production is the functional equivalent of an injunction.
- The order is not immediately appealable, and a writ of mandamus is unavailable because discovery rulings may be challenged only after final judgment.
Explanation: Whenever you see a discovery order in an appellate-procedure question, ask two things: Is it final? If not, is there an exception? Discovery orders are interlocutory, so immediate appeal is rare. Here, the defendant's privilege objection fails as a basis for a collateral-order appeal. The collateral order doctrine requires the order to be effectively unreviewable later, but after Mohawk Industries, even disclosure of privileged material does not make the order immediately appealable — the Supreme Court pointed to mandamus as the safeguard. The correct path is therefore that the order is not immediately appealable, but the defendant may seek a writ of mandamus if the privilege ruling was clearly erroneous and no adequate alternative remedy exists. Mandamus is extraordinary, but it exists precisely for clear abuses causing irreparable harm.
The choice saying the order is immediately appealable under the collateral order doctrine misunderstands Mohawk; the harm from disclosure, while serious, does not create collateral-order jurisdiction. The choice calling the order the "functional equivalent of an injunction" under §1292(a)(1) is a trap: discovery orders are not injunctions merely because they compel action. The choice saying a writ of mandamus is unavailable because discovery rulings may be challenged only after final judgment is too absolute — mandamus remains available in exceptional cases, including privilege disputes, where later review would be inadequate. Study tip: If a privilege order is at stake, remember Mohawk: no immediate appeal, but mandamus is the safety valve.
Question 6
A plaintiff brought federal claims for breach of fiduciary duty and fraud against a corporate defendant. The district court granted the defendant's motion for summary judgment on the fiduciary-duty claim, applying settled law to undisputed facts. The fraud claim remains pending and is set for trial. The plaintiff wants to appeal the fiduciary-duty ruling immediately. The district court has not made an express determination that there is no just reason for delay or directed entry of final judgment.
Which of the following best describes whether immediate appellate review is available?
- The ruling is immediately appealable because it fully disposes of one claim, even though another claim remains pending.
- The ruling is immediately appealable under the collateral order doctrine because it conclusively decides the fiduciary-duty claim separate from the pending fraud claim.
- The ruling is not immediately appealable unless the district court certifies a controlling question of law under §1292(b).
- The ruling is not immediately appealable unless the district court directs entry of final judgment under Rule 54(b). (correct answer)
Explanation: Whenever a party wants to appeal before the whole case is over, start with the final-judgment rule: only final decisions are appealable as of right, and a ruling that disposes of fewer than all claims is not final. Here, the summary judgment resolved only the fiduciary-duty claim while the fraud claim remains pending. Under Rule 54(b), that partial disposition can become immediately appealable only if the district court directs entry of final judgment on the claim and expressly finds no just reason for delay. The court made no such determination, so immediate appellate review is unavailable now; the plaintiff must wait for final judgment or a later Rule 54(b certification.
The suggestion that the ruling is immediately appealable merely because it fully disposes of one claim misunderstands Rule 54(b—adjudicating one claim is precisely the incomplete situation that rule governs. The collateral-order doctrine likewise does not apply: it is reserved for a narrow class of decisions that conclusively resolve issues truly collateral to the merits and would be effectively unreviewable on appeal from a final judgment. A summary judgment on the merits of a claim meets neither test. Section 1292(b also does not make the ruling appealable here; that statute allows discretionary interlocutory appeal of a controlling question of law with substantial ground for difference of opinion, but the summary judgment applied settled law to undisputed facts, so no such question is presented. And even under §1292(b, district court certification alone is not enough—the court of appeals must also permit the appeal. So with no Rule 54(b express determination, immediate appellate review is unavailable. When you see a partial claim disposition, immediately check for Rule 54(b language such as "no just reason for delay" before deciding appealability.
Question 7
Vega sued Delta Industries and Omega Corp on contract and tort claims. Delta moved for summary judgment on all claims asserted against it; Omega did not join. The district court granted Delta's motion, dismissed all claims against Delta, and stated in its order:
'The claims against Delta are separate from the claims against Omega. There is no just reason for delay. The clerk shall enter final judgment in favor of Delta and against Vega pursuant to Rule 54(b).'
Vega wants to appeal the dismissal of Delta now, while her claims against Omega remain pending.
Federal Rule of Civil Procedure 54(b) provides:
'When an action presents more than one claim for relief—whether as a claim, counterclaim, crossclaim, or third-party claim—or when multiple parties are involved, the court may direct entry of a final judgment as to one or more, but fewer than all, claims or parties only if the court expressly determines that there is no just reason for delay. Otherwise, any order or other decision, however designated, that adjudicates fewer than all the claims or the rights and liabilities of fewer than all the parties does not end the action as to any of the claims or parties and may be revised at any time before the entry of a judgment adjudicating all the claims and all the parties' rights and liabilities.'
Is Vega's appeal from the Rule 54(b) judgment properly before the court of appeals?
- Yes, because the district court dismissed all claims against Delta and included an express determination that there is no just reason for delay, so the judgment is final as to Delta under Rule 54(b). (correct answer)
- No, because the order does not end the action as to Omega, so it is not final; appeal cannot be taken unless all claims are resolved.
- No, because Rule 54(b) certification is available only when a single claim has been fully adjudicated, not when multiple parties remain in the case.
- Yes, because Vega may immediately appeal any order dismissing a party, even without Rule 54(b) certification, since Delta is no longer a party.
Explanation: Whenever you see an appeal from an order that resolves only part of a case, your first question should be: Is this a final judgment, or does it need Rule 54(b) certification? Rule 54(b) is the escape hatch from the general rule that only the entire action is appealable at the end—it lets the district court make a final judgment on fewer than all claims or parties, but only with an express "no just reason for delay" determination.
Here, the district court dismissed all claims against Delta, leaving only Omega. That is exactly the "fewer than all parties" situation Rule 54(b) addresses. Because the court stated the claims are separate, found no just reason for delay, and directed entry of final judgment, the judgment is final as to Delta and immediately appealable. So Vega's appeal is properly before the court of appeals.
The other choices each miss a key point. Saying "No, because the order does not end the action as to Omega" mistakes Rule 54(b) for a requirement that the entire case be finished—it permits partial final judgment. Saying "certification is available only when a single claim has been fully adjudicated" gets the rule backwards: Rule 54(b) expressly applies when multiple claims or multiple parties are involved. And saying Vega may appeal "any order dismissing a party, even without Rule 54(b) certification" is wrong, because a dismissal of fewer than all parties is not ordinarily final or appealable unless the district court gives that certification.
On the exam, when you see an appeal from a partial disposition, scan the order for the magic language: "final judgment" under Rule 54(b) plus an express "no just reason for delay." If both are present, the appeal is proper.
Question 8
Simone sought a temporary restraining order against a former employer; after notice and a hearing, the district court granted a TRO lasting 21 days, pending a preliminary-injunction hearing. The employer wants to appeal the TRO immediately.
The Interlocutory Appeals Act, §310(a), provides:
'Except as otherwise provided, appeal may be taken from an interlocutory order only if the order (1) grants, continues, modifies, refuses, dissolves, or refuses to dissolve or modify an injunction; (2) appoints a receiver; or (3) determines the rights and liabilities of parties in an admiralty case.
Section 310(b): A temporary restraining order is not an injunction for purposes of subsection (a)(1) unless it was issued after notice and a hearing and has an effective period extending beyond 14 days from the date of entry.'
Is the employer's immediate appeal of the temporary restraining order authorized under the Act?
- No, because a temporary restraining order is never treated as an injunction, regardless of notice, hearing, or duration.
- Yes, because all temporary restraining orders that are issued after a hearing are immediately appealable, regardless of duration.
- No, because a TRO is a temporary order that can be modified by the district court at any time and therefore is not sufficiently final to support interlocutory review.
- Yes, because the TRO was issued after notice and a hearing, and its effective period exceeds 14 days, so it falls within the Act's definition of an appealable injunction. (correct answer)
Explanation: When you see a TRO on a civil procedure or appellate jurisdiction question, check both halves of the statute: does the order fit the general definition of an injunction, and if it is a TRO, does it satisfy the special durational and procedural test? The Act makes TROs appealable only when they cross a threshold: they must be issued after notice and a hearing, and they must last longer than 14 days.
Here, the district court granted the TRO after notice and a hearing, and the TRO's effective period was 21 days—past the 14-day line. That makes it an "injunction" for purposes of §310(a)(1), so the employer may appeal immediately.
Now consider the distractors. The first says a TRO is never treated as an injunction—that ignores §310(b), which creates exactly this exception. The second says any post-hearing TRO is appealable regardless of duration—that misses the statute's separate 14-day requirement; a short TRO would not qualify. The third claims the TRO is not appealable because it is modifiable and not final—but the Act specifically authorizes interlocutory review of certain injunctive orders; modifiability does not defeat that statutory grant.
Strategy takeaway: whenever a question involves appealing a TRO, anchor yourself to the statutory language—notice, hearing, and duration. The exam loves testing whether you know the "14-day after notice and hearing" exception, so treat that phrase as a trigger for immediate appeal.
Question 9
A defendant in a federal contract action moved for summary judgment, arguing that the plaintiff's claim is barred by a limitations period in the contract. The district court denied the motion. The judge wrote that the limitations question has not been decided in this circuit, that two other circuits have reached opposite conclusions, and that an immediate appeal could avoid a costly trial or a second appeal. No injunction or class-certification order is involved, and no partial final judgment has been entered. The defendant wants review before trial.
What is the defendant's most appropriate course of action to obtain immediate appellate review?
- File a notice of appeal as of right, because the denial of summary judgment conclusively resolves a limitations defense separate from the merits.
- Petition the court of appeals for a writ of mandamus, because continuing the litigation would impose substantial and irreparable costs on the defendant.
- Ask the district court to certify the order for interlocutory appeal under §1292(b), and, if certified, petition the court of appeals for permission to appeal. (correct answer)
- No immediate appellate review is available; the defendant must raise the limitations defense in an appeal from a final judgment.
Explanation: A denial of summary judgment is ordinarily not immediately appealable. But here the trial judge's statements track the §1292(b) certification standard: a controlling question of law, substantial ground for difference of opinion, and an appeal that may materially advance the litigation. Thus the proper route is to obtain district court certification and then seek permission from the court of appeals. A is wrong because there is no as-of-right appeal for a denial of summary judgment, and a limitations defense is not a collateral matter. B is wrong because mandamus is not a substitute for discretionary review and ordinary litigation costs do not justify it. D is wrong because it ignores the available certification route.
Question 10
Amara Industries sued a former employee in federal court, alleging misappropriation of trade secrets. After the employee filed an answer, the court held a hearing on Amara's motion. Both sides appeared, called witnesses, and submitted exhibits. At the end of the hearing, the court entered an order labeled 'Temporary Restraining Order,' prohibiting the employee from using certain manufacturing processes. The order states that it will remain in effect 'until further order of this court' and requires Amara to post a $50,000 bond. The employee wants immediate appellate review, arguing that the processes are not trade secrets.
Which of the following is the most accurate statement about the employee's ability to obtain immediate appellate review?
- The order is immediately appealable as an injunction because, despite its label, it was entered after an adversary hearing and has no definite short-term expiration. (correct answer)
- The order is not immediately appealable because it is a temporary restraining order, and such orders generally may be reviewed only after final judgment, even when entered after a hearing.
- The order is immediately appealable under the collateral order doctrine because it finally resolves the trade-secret issue, that issue is separate from any later remedy, and awaiting final judgment would irreparably harm the employee.
- The order is immediately appealable only if the district court first certifies a controlling question of law for interlocutory appeal to the court of appeals under §1292(b).
Explanation: The order is treated as a preliminary injunction rather than a true temporary restraining order because it was entered after an adversary hearing and has no definite short-term expiration. An order that functions as a preliminary injunction is immediately appealable under §1292(a)(1). The label 'TRO' is not controlling. B is wrong because TROs ordinarily are not appealable, but the facts here show more than a true TRO. C is wrong because the trade-secret issue is the merits of the case, not a collateral matter. D is wrong because injunctive orders have a statutory right of interlocutory appeal and do not require §1292(b) certification.
Question 11
Empire Bank was ordered by a district court to produce privileged communications to the plaintiff, based on the court's finding that the crime-fraud exception applied. Empire Bank moved for reconsideration, which was denied. It then petitioned the court of appeals for a writ of mandamus, arguing that the communications are privileged, that the district court misapplied the crime-fraud exception, and that once produced the privilege would be lost and no effective review could be had after final judgment.
The Interlocutory Review Act provides:
'Sec. 2(a) A court of appeals may review an interlocutory order by writ of mandamus only if the petitioner establishes (1) a clear and indisputable right to the relief sought; (2) no adequate alternative means to obtain the relief; and (3) the writ is appropriate under the circumstances.
Sec. 2(b) An order compelling disclosure of material asserted to be privileged may be reviewed under subsection (a) notwithstanding that the order is not final; the petitioner need not defy the order and suffer contempt before seeking review.'
The court of appeals concludes that Empire Bank's privilege claim is plausible but that reasonable jurists could disagree whether the crime-fraud exception applies to these facts.
Should the court of appeals grant mandamus?
- Yes, because Section 2(b) expressly permits interlocutory mandamus review of privileged-material disclosure orders, and Empire Bank would have no adequate remedy after disclosure.
- No, because Empire Bank must first refuse to comply with the order and be held in contempt before a mandamus petition may be considered.
- No, because Empire Bank has not established a clear and indisputable right to withhold the documents, since reasonable jurists could disagree whether the crime-fraud exception applies. (correct answer)
- Yes, because mandamus is the only means to prevent disclosure of privileged communications, and a misapplication of the crime-fraud exception is a clear legal error.
Explanation: When you see a mandamus petition seeking review of a discovery order, start with the statutory test: a writ requires a clear and indisputable right, no adequate alternative remedy, and appropriateness under the circumstances. The special provision in Section 2(b) removes two barriers—finality and the need to risk contempt—but it does not relax the clear-right requirement.
Here, Empire Bank has a plausible privilege claim, but plausible is not enough. Because reasonable jurists could disagree about whether the crime-fraud exception applies, Empire Bank has not shown a clear and indisputable right to withhold the documents. Mandamus is extraordinary relief, not a tool for ordinary legal error or close calls, so the court should deny the writ.
The choice saying Section 2(b) expressly permits interlocutory review and there is no adequate remedy after disclosure is tempting, but it conflates "reviewable" with "must be granted." The bank still must satisfy every element of Section 2(a). The choice insisting the bank must first refuse compliance and be held in contempt is directly contradicted by Section 2(b), which says no such defying order is needed. Finally, the choice arguing mandamus is the only means and the misapplication is clear legal error overstates the record: a debatable application of the exception is not a clear error, and even sole means of review does not make the right "clear and indisputable."
Study tip: whenever a statute creates special interlocutory review, check whether it changes the ultimate standard or only removes procedural obstacles. Here, Section 2(b) merely opens the door; it does not lower the bar.
Question 12
Martinez filed a putative class action against PayRite, Inc. alleging statutory wage violations. On March 3, the district court entered an order denying class certification. On March 17, Martinez filed an application with the court of appeals for permission to appeal the denial. PayRite opposes the application, arguing that it is untimely and that in any event immediate review is not warranted because the district court's ruling was correct.
Federal Rule of Civil Procedure 23(f) provides:
'A court of appeals may in its discretion permit an appeal from an order granting or denying class-action certification under this rule if a party files an application for permission to appeal within 14 days after the order is entered. An appeal does not stay proceedings before the district court unless the district judge or the court of appeals so orders.'
Which of the following statements best describes whether the court of appeals may review the class-certification denial?
- It may review the denial if it chooses, because Martinez's application was timely and Rule 23(f) makes review discretionary. (correct answer)
- It may not review the denial because a class-certification order is interlocutory and review may occur only after final judgment.
- It may review the denial only by writ of mandamus, because Rule 23(f) does not authorize review of an order denying certification.
- It may review the denial as of right, because Martinez timely invoked Rule 23(f) and the court of appeals must decide the merits of the certification question.
Explanation: This question tests the narrow exception to the final-judgment rule for class-action certification orders. While certification orders are normally interlocutory, Rule 23(f) creates a specific, discretionary window for immediate appeal. To answer, check the timing and the permissive language. Here, the district court entered the order on March 3, and Martinez filed the application on March 17 – exactly 14 days later, so it is timely. The rule states the court of appeals "may" permit an appeal, which means the decision is entirely discretionary. Therefore, the court may review the denial if it chooses – it is not obligated to, but it is not barred from doing so. The choice claiming the court may not review because the order is interlocutory and review occurs only after final judgment is wrong because Rule 23(f) is precisely an exception to that rule. The choice saying review is available only by writ of mandamus is also incorrect, since Rule 23(f) explicitly authorizes review of orders denying certification. Finally, the choice stating the court must review the denial as of right misreads the permissive "may" – the court of appeals has discretion, not a mandatory duty, to decide the merits. Remember: in procedural rules, "may" signals discretion, while "must" or "shall" signals a mandatory duty. Always check for special appeal windows like Rule 23(f) – they override the general final-judgment rule.
