What Is Interlocutory Review Under 28 U.S.C. § 1292(b)?

Interlocutory review under 28 U.S.C. § 1292(b) is a discretionary procedure that may permit a federal court of appeals to review an important legal ruling before the district court enters final judgment. It is available only when the district judge certifies that the ruling involves a controlling question of law, substantial grounds exist for disagreement, and an immediate appeal may materially advance the end of the litigation.

Certification by the district judge is only the first step. The appropriate federal court of appeals must separately agree to accept the appeal, and it may decline review even when the district court concludes that all three statutory criteria are satisfied.

The Answer Depends On…

Whether interlocutory review is available and strategically appropriate depends on:

• Whether the case is a federal civil action

• Whether the challenged ruling is otherwise immediately appealable

• Whether the ruling presents a controlling question of law

• Whether the question can be resolved without an extensive factual inquiry

• Whether substantial grounds exist for disagreement about the legal answer

• Whether appellate resolution could end the case or materially narrow it

• Whether the district judge is willing to certify the order

• Whether the court of appeals is willing to exercise its discretion

• Whether the petition can be filed within the statutory 10-day period

• Whether trial, discovery, or other district-court proceedings will continue

• Whether the party needs a separate stay pending appellate review

• Whether the record and certified order frame the legal question clearly

• Whether immediate review will save substantial time and expense or merely interrupt the litigation

• Whether another route—such as § 1292(a), Rule 54(b), Rule 23(f), the collateral-order doctrine, mandamus, or an appeal after final judgment—is more appropriate

• Whether the case arises in a Florida federal district court subject to Eleventh Circuit review or a North Carolina federal district court subject to Fourth Circuit review

• Whether the issue could later affect en banc review, a petition for writ of certiorari, or broader amicus participation

Section 1292(b) is not a general procedure for appealing every important or disputed pretrial ruling. It is a narrow exception to the federal final-judgment rule.

Why Is § 1292(b) Necessary?

Under 28 U.S.C. § 1291, federal appellate jurisdiction ordinarily begins only after the district court enters a final decision resolving the litigation. This rule generally requires the parties to complete the entire district-court case before asking the court of appeals to review alleged errors.

The final-judgment rule serves several purposes:

• Preventing fragmented appeals

• Reducing delay

• Allowing the district court to develop a complete record

• Combining multiple potential errors into one appeal

• Avoiding appellate review of issues that later become irrelevant

• Preserving the trial judge’s ability to manage the case

But in some cases, waiting until final judgment would require the parties and court to complete years of discovery, motion practice, and trial proceedings even though a threshold legal issue could end or dramatically narrow the litigation.

Section 1292(b) creates a limited two-court procedure for those unusual cases. The district court acts as the first gatekeeper, and the court of appeals acts as the second. Both must agree that immediate appellate consideration is appropriate.

What Are the Three Requirements for § 1292(b) Certification?

The district judge must state in writing that the order involves:

1. A controlling question of law

2. A substantial ground for difference of opinion

3. A possibility that immediate appeal may materially advance the ultimate termination of the litigation

All three requirements must be addressed. A difficult or important issue does not automatically satisfy the statute.

What Is a Controlling Question of Law?

A controlling question is generally a legal issue whose resolution could materially affect the course or outcome of the litigation.

The issue may be controlling when an appellate ruling could:

• Require dismissal of the entire case

• Eliminate one or more major claims

• Resolve subject-matter jurisdiction

• Determine whether federal law preempts the claims

• Establish which statute or legal framework governs

• Determine whether a category of damages is legally available

• Resolve an unsettled statutory-interpretation issue

• Determine whether a legal defense bars the action

• Eliminate the need for extensive discovery or trial

• Substantially change the parties, issues, or scope of the case

A question does not always have to dispose of the entire lawsuit to be controlling. It may qualify when the answer would materially affect a substantial part of the litigation.

The question usually should be predominantly legal

Section 1292(b) works best when the court of appeals can decide a relatively clean legal issue without conducting an intensive review of disputed facts.

Examples may include:

• What a federal statute means

• Whether a particular federal cause of action exists

• Whether one federal law preempts another claim

• Whether a legal doctrine applies to an identified category of claims

• Which limitations period applies as a matter of law

• Whether federal jurisdiction exists under an agreed procedural record

• Whether a governing precedent forecloses a legal theory

The Eleventh Circuit has emphasized that § 1292(b) generally requires a pure question of law. In one published decision, it vacated previously granted permission because deciding the issue would have required resolving disputed, case-specific factual questions rather than answering a clean legal issue. The court also reaffirmed that it retains discretion to reject review even when the statutory factors appear to be present.

The Fourth Circuit similarly has explained that interlocutory review is more appropriate for a pure legal question that can be decided quickly and cleanly than for an issue requiring the court to delve into the factual record. It has cautioned that § 1292(b) should be used sparingly.

What usually is not a pure question of law?

The following issues are less likely to be suitable:

• Whether the evidence is sufficient

• Whether a witness is credible

• Whether disputed facts satisfy a settled legal test

• Whether the district court correctly weighed competing evidence

• Whether a party acted reasonably under the particular circumstances

• Whether an expert’s case-specific opinion is persuasive

• Whether the judge properly applied settled law to a complicated factual record

• Whether summary judgment should be granted because of disputed factual inferences

A party should not try to convert a fact-intensive disagreement into a “question of law” merely by phrasing the question broadly.

What Is a Substantial Ground for Difference of Opinion?

The second requirement asks whether there is a meaningful legal basis for disagreement about the answer.

Substantial grounds may exist when:

• Federal courts of appeals disagree

• District courts within the circuit have reached conflicting conclusions

• The controlling circuit has not resolved the question

• Other circuits apply materially different legal tests

• The issue involves conflicting interpretations of statutory language

• Existing precedent points in different directions

• A recent Supreme Court decision creates uncertainty about older circuit precedent

• The issue is exceptionally difficult and the authorities provide no clear answer

The inquiry is not whether the losing party disagrees with the judge. Nor is novelty by itself necessarily sufficient.

A party generally should identify:

• The competing legal authorities

• The specific conflict among those authorities

• Why the conflict is genuine rather than factual

• Why existing circuit or Supreme Court precedent does not already supply the answer

• Why reasonable jurists could adopt materially different interpretations

What is usually insufficient?

The following ordinarily do not establish a substantial ground for disagreement by themselves:

• The absence of a case with identical facts

• A party’s strong disagreement with the ruling

• A novel argument unsupported by competing authority

• Conflicting interpretations of the evidence

• The possibility that another judge might have ruled differently

• A difficult application of settled law to unusual facts

• A claim that the district court simply made an error

The certification motion should present the disagreement as a legal conflict, not merely an assertion that the order was wrong.

What Does “Materially Advance the Ultimate Termination” Mean?

The third requirement asks whether immediate appellate review could meaningfully shorten or simplify the case.

An immediate appeal may materially advance the litigation when it could:

• End the entire action

• Eliminate the need for trial

• Avoid broad and expensive discovery

• Resolve claims affecting hundreds or thousands of transactions

• Remove an entire theory of liability or damages

• Determine whether the case belongs in federal court

• Narrow the number of parties

• Prevent duplicative proceedings

• Establish a legal framework controlling the remaining litigation

• Avoid a trial that might have to be repeated

The stronger the relationship between the legal question and the time, expense, and complexity remaining in the district court, the stronger the argument for certification.

A ruling does not materially advance the case merely because it is important

Certification may be inappropriate when:

• The case will require substantially the same discovery regardless of the answer

• The appeal would resolve only a minor issue

• Other independent claims will require the same trial

• The factual record remains undeveloped

• The question may become irrelevant after later rulings

• Appellate proceedings would delay a near-term trial

• Immediate review would fragment the litigation without creating significant efficiencies

The certification motion should explain concretely what proceedings would be avoided or narrowed—not merely assert that appellate guidance would be helpful.

Is § 1292(b) Review a Right?

No.

Section 1292(b) establishes a discretionary process at both levels.

First gatekeeper: the district court

The district court must determine that the three statutory requirements are satisfied and include the necessary written statement in the order.

If the original ruling does not contain certification, Federal Rule of Appellate Procedure 5 permits the district court to amend the order, either on its own or in response to a party’s motion, to include the required statement. The petition deadline then runs from the entry of the amended certified order.

Second gatekeeper: the court of appeals

District-court certification does not create an automatic appeal. The litigant must petition the proper federal court of appeals for permission, and the appellate court independently decides whether to accept the case.

The Fourth Circuit has described this arrangement as requiring sequential and independent discretion from the district court and the court of appeals.

The court of appeals may deny permission even when:

• The district court certified the issue

• The three statutory factors arguably are present

• Both parties support immediate review

• The issue is nationally important

• The appellate court eventually might review the issue after final judgment

What Is the Deadline for a § 1292(b) Petition?

The petition for permission to appeal must be filed in the court of appeals within 10 days after entry of the order containing the required certification.

If the district court later amends its original order to include the § 1292(b) certification, the 10-day period begins upon entry of the amended order.

The 10-day deadline cannot be extended by the court of appeals

Federal Rule of Appellate Procedure 26 states that the court may not extend the time to file a petition for permission to appeal. Every day is generally counted, including intervening Saturdays, Sundays, and legal holidays, subject to the rules governing the final day of a filing period.

This deadline is dramatically shorter than the usual 30-day deadline for an ordinary federal civil notice of appeal.

Counsel should not wait until the district court grants certification to begin drafting the Rule 5 petition.

How Does a Party Request Certification?

The party ordinarily files a motion in the district court asking the judge to amend or certify the relevant order.

The motion should identify:

• The exact order to be certified

• The precise controlling question of law

• The competing legal authorities

• The substantial grounds for disagreement

• The proceedings that immediate review could avoid

• Why the question is sufficiently independent of factual disputes

• Why certification will promote efficiency rather than delay

• Whether the party will request a stay

• The proposed certification language

A proposed question should be written neutrally. A question that assumes disputed facts, argues the merits, or combines multiple unrelated issues may reduce the likelihood of certification.

Is there a federal deadline to ask the district court for certification?

Section 1292(b) does not state a separate numerical deadline for filing the district-court motion to certify.

But the request should be made promptly.

Delay can undermine the argument that:

• Immediate review is necessary

• The question is controlling

• The appeal will materially advance the litigation

• The request is intended to promote efficiency rather than postpone proceedings

Local rules, scheduling orders, or the district judge’s practices may also affect the procedure.

What Must the Rule 5 Petition Contain?

Federal Rule of Appellate Procedure 5 requires the petition to include:

• The facts necessary to understand the question

• The question presented

• The relief sought

• The reasons the appeal should be allowed

• The statutory or rule-based authority for the appeal

• A copy of the challenged order and related opinion or memorandum

• A copy of the order containing the district court’s certification

A computer-generated petition generally may not exceed 5,200 words, excluding the required attached orders and the items excluded under Rule 32.

The petition should explain not only why the district court’s ruling is erroneous, but why immediate appellate intervention is justified under the statutory criteria.

How long does the other side have to respond?

A party may file an answer in opposition or a cross-petition within 10 days after service of the petition.

The petition and answer generally are decided without oral argument unless the court of appeals orders otherwise.

Is a Notice of Appeal Required?

Not at the petition stage.

The party files a petition for permission to appeal directly with the circuit clerk under Federal Rule of Appellate Procedure 5.

If the court of appeals grants permission:

• The appellant generally has 14 days to pay the required fees to the district clerk

• A cost bond must be filed if required under Rule 7

• No separate notice of appeal is necessary

• The date of the order granting permission is treated as the notice-of-appeal date for purposes of the appellate rules

The district clerk then notifies the circuit clerk after the fees are paid, and the appeal proceeds onto the regular appellate docket.

Does a § 1292(b) Petition Automatically Stay the Federal Case?

No.

Section 1292(b) expressly states that an application for permission to appeal does not stay district-court proceedings unless the district judge, the court of appeals, or an appellate judge orders a stay.

The case therefore may continue through:

• Discovery

• Depositions

• Expert disclosures

• Dispositive-motion briefing

• Pretrial proceedings

• Settlement conferences

• Trial preparation

• Trial itself

The party seeking interlocutory review should evaluate stay relief at the same time it seeks certification.

Where should the party request a stay?

Federal Rule of Appellate Procedure 8 generally requires a party to seek a stay first from the district court before asking the court of appeals, unless applying first to the district court would be impracticable.

The stay request should address:

• Likelihood of success

• Irreparable harm

• Harm to the opposing party

• The public interest

• The duration and scope of the requested stay

• Whether a partial stay would be sufficient

• Whether discovery can continue on unrelated matters

• Whether appellate review could become meaningless without a stay

A § 1292(b) petition and a stay motion are separate filings serving different purposes.

What Issues Can the Court of Appeals Review?

The district court typically frames a controlling question of law, but appellate jurisdiction attaches to the certified order, not only to the exact sentence used to formulate the question.

The Supreme Court has explained that a court of appeals accepting a § 1292(b) case may address issues fairly included within the certified order.

That does not mean the court must decide every issue related to the order. The appellate court retains discretion over the appropriate scope of review.

This creates both an opportunity and a risk:

• An appellant may obtain review of an issue closely connected to the certified question

• An appellee may defend the order on an alternative legal ground

• The court may reformulate the question

• The court may decide a threshold jurisdictional issue

• The court may avoid a broader issue if a narrower ground resolves the order

Counsel should evaluate the entire certified order, not merely the proposed question.

When Does § 1292(b) Review Make the Most Sense?

Interlocutory review may be especially useful when a threshold legal ruling controls a large or expensive federal case.

Potential examples include:

Subject-matter jurisdiction

A controlling legal question about federal jurisdiction may determine whether the case can proceed at all.

Federal statutory interpretation

The district court may adopt an interpretation of a federal statute that controls every claim or a large category of cases.

Preemption

A legal determination about federal preemption may eliminate state-law claims or substantially change the case.

Constitutional questions

A district-court ruling may resolve a threshold constitutional issue governing the entire action.

Availability of a cause of action

Immediate review may determine whether federal law recognizes the asserted claim.

Legal availability of damages or remedies

A ruling on whether a category of damages, restitution, or statutory relief is legally available may reshape the litigation.

Claims involving massive discovery

A threshold legal issue may determine whether the parties must complete unusually expensive, burdensome, or sensitive discovery.

Large multidistrict or aggregated litigation

A common legal issue may affect numerous claims, parties, or coordinated actions.

Government or regulatory litigation

A controlling legal question may determine the scope of governmental authority, statutory enforcement, or constitutional limits.

The analysis remains case-specific. A legal issue can be important without being appropriate for immediate review.

When Is § 1292(b) Review Usually a Poor Fit?

Certification is less likely to be appropriate when:

• The dispute is primarily factual

• The question asks whether the judge correctly applied settled law to the evidence

• Extensive record review is required

• The ruling affects only a minor issue

• The same trial will occur regardless of the answer

• Discovery is nearly complete and trial is imminent

• The issue may become moot or unnecessary

• The proposed question is framed too broadly

• The party is attempting to obtain early review of an ordinary denial of summary judgment

• The request appears designed primarily to delay the litigation

• Another immediate-appeal statute or rule governs the order

• The issue can be adequately reviewed after final judgment

A party should compare the likely duration of interlocutory review with the time that would be required to proceed toward final judgment.

How Is § 1292(b) Different From Other Federal Appellate Routes?

Section 1292(a)

Section 1292(a) permits appeals as of right from specified categories of interlocutory orders, including certain orders granting, denying, modifying, or dissolving injunctions and specified receivership orders.

A § 1292(a) appeal does not require district-court certification or discretionary permission under Rule 5.

Federal Rule of Civil Procedure 54(b)

Rule 54(b) applies when the district court enters final judgment as to one or more—but fewer than all—claims or parties and determines that there is no just reason for delay.

Section 1292(b), by contrast, concerns a nonfinal order presenting a qualifying controlling legal question.

Federal Rule of Civil Procedure 23(f)

Rule 23(f) permits a party to seek discretionary review of an order granting or denying class certification.

It has its own procedure and deadline and does not require § 1292(b) certification.

The collateral-order doctrine

A narrow category of orders may be immediately appealable under § 1291 because they conclusively resolve an important issue separate from the merits that would be effectively unreviewable after final judgment.

The doctrine is limited and should not be treated as a substitute for § 1292(b).

Mandamus

A petition for writ of mandamus seeks extraordinary relief based on a clear and indisputable right and the absence of an adequate alternative remedy.

Mandamus ordinarily cannot be used merely to bypass a district court’s refusal to certify an issue under § 1292(b). The Fourth Circuit has emphasized the district court’s independent gatekeeping role and the extraordinary nature of mandamus.

Appeal after final judgment

When no immediate route exists, the party ordinarily must preserve the issue, complete the district-court proceedings, and raise the issue in an appeal from the final judgment.

Florida Federal Cases: Eleventh Circuit Review

Federal civil cases arising in the:

• Southern District of Florida

• Middle District of Florida

• Northern District of Florida

generally proceed to the U.S. Court of Appeals for the Eleventh Circuit.

The Eleventh Circuit treats § 1292(b) review as discretionary and emphasizes that the issue generally should be a pure question of law rather than a fact-intensive application of settled principles.

Even after initially granting permission, the Eleventh Circuit may later conclude that the statutory requirements are not satisfied, vacate the grant, and dismiss the interlocutory appeal.

Counsel should review the current Federal Rules of Appellate Procedure, Eleventh Circuit Rules, filing requirements, disclosure rules, and electronic-filing procedures before submitting the petition. The Eleventh Circuit identifies its rules effective April 1, 2026, as the current version.

North Carolina Federal Cases: Fourth Circuit Review

Federal civil cases arising in the:

• Western District of North Carolina

• Middle District of North Carolina

• Eastern District of North Carolina

generally proceed to the U.S. Court of Appeals for the Fourth Circuit.

The Fourth Circuit has warned that § 1292(b) should be used sparingly and that its requirements should be strictly construed. It distinguishes clean legal questions from issues requiring detailed factual analysis.

Under Fourth Circuit Local Rule 5:

• The petition initially is placed on the miscellaneous docket

• No docket fee is required unless permission is granted

• A corporate-disclosure statement must accompany the petition and answer

• If permission is granted, the court transfers the matter to its regular docket

Important § 1292(b) Deadlines and Requirements

Step	General requirement
Request district-court certification	Promptly after the interlocutory ruling
District-court certification	Written statement satisfying all three statutory factors
Petition to the court of appeals	Within 10 days after entry of the certified order
Extension of petition deadline	Not permitted by the court of appeals
Answer or cross-petition	Within 10 days after service of the petition
Petition length	Generally 5,200 words
Oral argument on permission	None unless ordered
Fees after permission is granted	Generally within 14 days
Separate notice of appeal	Not required after permission is granted
Automatic stay	None

These deadlines and requirements arise from § 1292(b), Federal Rules of Appellate Procedure 5 and 26, and applicable circuit rules.

What Evidence and Materials Should Counsel Review?

Although the certified issue should be legal, the petition must present enough of the record to explain the procedural posture and importance of the question.

Counsel should review:

• The operative complaint and answer

• Counterclaims and third-party claims

• The motion producing the challenged order

• Responses and replies

• The district court’s order and memorandum

• Relevant statutes and regulations

• Controlling circuit and Supreme Court decisions

• Conflicting district- or circuit-court authority

• Any hearing transcript

• Undisputed facts necessary to frame the legal question

• The scheduling order

• Discovery completed and remaining

• Estimated discovery and trial burdens

• The order granting certification

• Potential stay materials

• Related cases presenting the same issue

The petition should not depend on facts that were never presented to the district court.

A Practical § 1292(b) Strategy Framework

Step 1: Classify the order

Determine whether the order already is appealable through:

• Section 1292(a)

• Rule 23(f)

• Rule 54(b)

• The collateral-order doctrine

• Another statute

• An extraordinary writ

Section 1292(b) applies to an order not otherwise appealable under § 1292.

Step 2: Formulate one focused legal question

The strongest question usually:

• Is concise

• Is neutral

• Does not assume disputed facts

• Can be answered without reviewing a massive record

• Controls a significant part of the case

• Connects directly to the challenged order

Step 3: Identify the genuine legal disagreement

Collect the competing circuit, district-court, Supreme Court, statutory, or doctrinal authorities.

Step 4: Quantify the procedural benefit

Explain what immediate review may eliminate or narrow:

• Months of discovery

• Expert proceedings

• A lengthy trial

• Multiple claims

• Numerous parties

• Duplicative lawsuits

• Substantial litigation expense

Step 5: Seek certification promptly

Prepare the certification motion, proposed question, and proposed amended order.

Step 6: Begin the Rule 5 petition immediately

Do not wait for the certification order. The 10-day petition period is short and cannot be extended.

Step 7: Evaluate a stay simultaneously

Determine what district-court proceedings will continue and whether continuing those proceedings would defeat the benefit of review.

Step 8: Plan for denial

Certification and permission are discretionary. Continue preserving the issue and preparing the district-court case unless a stay is entered.

What Are the Principal Risks of Seeking Interlocutory Review?

The district judge may refuse certification

Without district-court certification, the ordinary § 1292(b) process cannot proceed.

The court of appeals may deny permission

Certification does not guarantee appellate review.

The appellate court may reject the question as fact-intensive

A question that appears legal may require an extensive examination of the record.

The district-court case may continue

The petition and appeal do not create an automatic stay.

The appeal may increase rather than reduce delay

The parties may complete permission proceedings and appellate briefing only to return to substantially the same district-court case.

The court may review more than the framed question

Because jurisdiction extends to the certified order, closely related issues may enter the appellate court’s analysis.

An adverse appellate ruling may become binding

An immediate loss can eliminate arguments, reshape discovery, increase settlement pressure, or govern the remainder of the case.

The request may reveal strategy

A certification motion may identify the issue the party considers most important or vulnerable.

A procedural error may forfeit immediate review

The statutory 10-day deadline is extremely short and cannot be enlarged by the court of appeals.

What Can the Court of Appeals Do?

If permission is granted, the court of appeals may:

• Affirm the certified order

• Reverse the order

• Vacate the order

• Remand for further proceedings

• Reformulate the question

• Resolve a threshold jurisdictional issue

• Address an issue fairly included within the certified order

• Narrow the scope of the district-court ruling

• Require dismissal of claims

• Require application of a different legal standard

• Return the case for factual development

If permission is denied, the district-court litigation continues. Denial of permission generally does not decide the legal merits of the issue, which may remain available for review after final judgment if properly preserved.

Frequently Asked Questions

Is a § 1292(b) appeal automatic after the district court certifies the order?

No. The district court’s certification only authorizes the party to petition the court of appeals. The appellate court independently decides whether to accept the appeal and may deny permission even when the district judge believes the statutory requirements are satisfied.

How much time do I have to petition the court of appeals?

The petition generally must be filed within 10 days after entry of the order containing the § 1292(b) certification. The court of appeals may not extend that deadline.

Can the district court certify an older order?

Federal Rule of Appellate Procedure 5 permits the district court to amend an earlier order to include the required certification. When it does so, the 10-day petition period runs from entry of the amended certified order. The court may nevertheless consider whether the party requested certification promptly.

What qualifies as a controlling question of law?

A controlling question generally is a predominantly legal issue whose resolution could end the case or materially change a substantial part of it. A dispute requiring the court of appeals to resolve contested facts ordinarily is a poor candidate.

Does disagreement with the district judge establish a substantial ground for difference of opinion?

No. The movant ordinarily should identify conflicting authority, unresolved precedent, competing statutory interpretations, or another objective legal basis for meaningful disagreement.

Does filing the petition stop discovery or trial?

No. Section 1292(b) expressly provides that the application does not stay district-court proceedings unless the district court or court of appeals orders a stay.

Do I file a notice of appeal after the court of appeals accepts the case?

No separate notice of appeal is required. The order granting permission serves as the notice-of-appeal date for purposes of the appellate rules, although fees and any required cost bond generally must be addressed within 14 days.

Can the appellate court decide issues beyond the precise certified question?

Potentially. The Supreme Court has held that jurisdiction attaches to the certified order, allowing the appellate court to consider issues fairly included within that order. The appellate court retains discretion over the scope of its review.

Schedule a Litigation Strategy Review

Section 1292(b) can prevent years of unnecessary litigation when a clean, disputed legal question controls the direction of a federal case. It can also create delay and expense when the issue is fact-intensive, marginal, or unlikely to be accepted by both courts.

The analysis should begin immediately after the district court enters the significant ruling because the certification strategy, proposed question, stay request, record, and nonextendable petition deadline must be coordinated carefully.

Schedule a litigation strategy review to evaluate whether the ruling presents a controlling question of law, whether substantial grounds for disagreement exist, whether immediate review could materially advance the case, how to frame the certification request, whether a stay is necessary, and whether the Fourth Circuit, Eleventh Circuit, or another federal court of appeals is likely to accept the petition.

This article provides general information and is not legal advice. Section 1292(b) certification, Rule 5 deadlines, appellate jurisdiction, stays, and preservation depend on the particular order, district, circuit, record, and procedural posture. Reading this article does not create an attorney-client relationship. Past results do not guarantee future outcomes.
