How Can a Company Protect Sealed, Privileged, or Confidential Information in a U.S. Supreme Court Petition, Appendix, or Brief? U.S. Supreme Court—Nationwide
A company can protect sensitive material by first asking whether the information needs to be filed at all, then using required personal-identifier redactions or a narrowly tailored motion for leave to file material under seal under Supreme Court Rule 34.7. A lower-court seal does not automatically guarantee continued sealing in the U.S. Supreme Court, and material containing sealed information—including related public redacted copies—must not be submitted through the Court’s electronic filing system.
Privilege requires separate treatment. Filing a privileged document under seal may protect it from public access, but sealing does not necessarily prevent waiver, disclosure to other parties, or use by the Court; counsel should determine whether the filing is legally necessary before submitting it.
The answer depends on…
whether the material is attorney-client privileged, work product, trade secret, confidential commercial information, personal identifying information, health information, source code, customer data, personnel information, or merely embarrassing;
whether it was sealed in the trial court, agency, court of appeals, Florida court, North Carolina court, or another tribunal;
whether the lower-court sealing order remains in effect for each document;
whether the Supreme Court petition, brief, or appendix actually needs the sensitive material;
whether the point can be made through a citation, description, stipulation, summary, or narrower excerpt;
whether mandatory redaction under Supreme Court Rule 34.6 is sufficient;
whether broader redaction requires a motion;
whether a public redacted version can be prepared;
whether sealed appendix material can be isolated in a separate supplemental volume;
whether another party or nonparty owns or shares the confidentiality interest;
whether filing privileged material could waive protection or create subject-matter consequences;
whether a protective order authorizes appellate or Supreme Court use;
whether the filing involves a petition, brief in opposition, merits brief, joint appendix, amicus brief, motion, or emergency application;
whether a disclosure deadline requires a stay before certiorari review can be meaningful;
whether the Court’s paper-filing, service, and labeling requirements have been followed; and
whether counsel has removed sensitive information from metadata, certificates, tables, captions, and public descriptions—not just the main text.
Four Different Problems Require Four Different Solutions
The word “confidential” is too broad to determine the procedure. Start by classifying the material.
Type of information | Primary concern | Typical first response |
Personal identifiers | Identity theft, privacy, mandatory court rules | Apply Rule 34.6 and the incorporated federal redaction rule |
Material sealed below | Continued public-access protection | Evaluate a Rule 34.7 motion and provide the lower-court sealing order |
Privileged or work-product material | Waiver and compelled disclosure, not merely public access | Avoid filing unless necessary; analyze waiver and scope before sealing strategy |
Trade secrets or confidential business information | Competitive and commercial harm | Minimize, narrowly redact, and seek sealing with evidence of continuing need |
A protective order, confidentiality designation, and sealing order are not interchangeable. A discovery agreement may restrict how parties use information without making it secret from the courts or public once filed. A document marked “Confidential” by a party may never have been judicially sealed. Rule 34.7 requires the Supreme Court movant to explain the actual status.
First Principle: Do Not File Sensitive Material Unless the Court Needs It
The most reliable protection is disciplined omission. Before preparing a sealing motion, ask:
Is the material required by Rule 14, Rule 24, Rule 26, or another applicable rule?
Is it necessary to establish jurisdiction, preservation, the Question Presented, the lower court’s holding, an alternative ground, or the requested relief?
Can the filing cite the sealed record without reproducing the protected text?
Can a narrow excerpt replace an entire document?
Can neutral terminology convey the point?
Can the parties stipulate to a public description?
Would omitting the material create a misleading presentation?
A certiorari petition generally does not reproduce the entire record. Rule 14 specifies required appendix materials, and the filing should include what the Court needs to evaluate jurisdiction, certworthiness, and the case—not every document produced below.
At the merits stage, the full lower-court record is available to the Justices. Rule 26 states that counsel may cite relevant record portions not reproduced in the joint appendix. That may reduce the need to republish sensitive exhibits, although any public description still must be carefully drafted.
Rule 34.6: Redact Personal Identifying Information
Supreme Court Rule 34.6 carries forward the privacy rule that governed below—such as Federal Rule of Appellate Procedure 25(a)(5), Federal Rule of Bankruptcy Procedure 9037, Federal Rule of Civil Procedure 5.2, or Federal Rule of Criminal Procedure 49.1. In other cases, Rule 34.6 generally applies Civil Rule 5.2, with Criminal Rule 49.1 governing an extraordinary writ in a criminal matter.
Depending on the applicable rule, required redactions commonly include:
all but the last four digits of a Social Security or taxpayer-identification number;
the year of an individual’s birth rather than the full date;
a minor’s initials rather than the full name; and
all but the last four digits of a financial-account number.
The March 2026 electronic-filing guidelines state that no motion is required to make the redactions mandated by Rule 34.6. A party may move to redact additional information in appropriate circumstances. Counsel and the parties—not the Clerk—bear responsibility for redaction.
Mandatory identifier redaction does not automatically protect trade secrets, privileged communications, proprietary pricing, customer identities, or other commercial information. Those interests require a separate analysis.
Rule 34.7: A Lower-Court Seal Is Relevant but Not Self-Executing
Where circumstances warrant, Rule 34.7 permits a party to move for leave to file material under seal. The motion should address:
Lower-court status. Was the material sealed below? If so, provide the sealing order where applicable.
Reasons and continuing effect. Why was it sealed, does the seal remain effective for each document, and why is confidentiality still needed in the Supreme Court?
First-instance sealing. If the material was not sealed below, explain with specificity why sealing is necessary for the first time in the Supreme Court.
Necessity. Explain why the sealed material must be included in the filing.
Public access. Provide a redacted public copy where possible, or explain why that is infeasible.
Separate volume. If the sealed material is part of an appendix, place it in a separate supplemental appendix volume.
Public motion if possible. Draft the sealing motion itself for the public record where feasible; otherwise provide a public redacted motion if possible.
Other parties’ positions. State whether the other parties agree, oppose, or take no position.
The motion must comply with Rule 21. Filing a motion does not justify casual disclosure while it is pending: Rule 34.7 directs the parties to treat the material as under seal until the Court rules.
Label Every Sealed and Public Version Correctly
Rule 34.7 requires material sought to be sealed to bear “Under Seal” on the cover and every page. A redacted public version should state “Public Copy—Sealed Materials Redacted” on its cover.
The labeling review should extend beyond the main document. Check:
front and back covers;
every page of a sealed appendix volume;
appendix tables of contents;
bookmarks and internal PDF titles;
exhibit separators;
certificates and proofs of service;
cover letters;
file names;
document properties and metadata; and
printer manifests or transmittal emails.
A public table of contents that spells out the protected information can defeat otherwise careful redaction.
Do Not Electronically File or Electronically Serve Sealed Material
The Court’s March 2026 electronic-filing guidelines contain a critical warning: filings containing sealed material, documents sealed in lower courts, and motions to file under seal should not be submitted through the Supreme Court’s electronic filing system.
The prohibition also applies to associated public documents. If a public petition has a public appendix plus a supplemental appendix proposed for sealing, the petition, public appendix, sealed supplemental appendix, sealing motion, and related redacted versions should be submitted only in paper form under the current guidance. They also should not be served electronically.
This matters because electronically submitted documents may be posted publicly before Clerk’s Office personnel review them. An accidental upload can cause the exact disclosure the sealing motion was intended to prevent.
Counsel should contact the appropriate Clerk’s Office personnel before filing if the package will contain sealed material, particularly in a merits case or emergency posture. The filing plan should be confirmed against the current rules, guidance, and any case-specific direction.
Privilege Is Not the Same as Confidentiality
Attorney-client privilege and work-product protection concern compelled disclosure and protected legal communications or litigation preparation. A court seal primarily governs public access. One does not automatically preserve the other.
Before filing privileged material, counsel should determine:
who owns and may waive the privilege;
whether disclosure has already occurred and under what protection;
whether the material was placed at issue;
whether an exception or waiver doctrine is asserted;
whether filing with the Court or serving an adversary would create waiver;
whether a selective or subject-matter waiver argument may follow;
whether Federal Rule of Evidence 502 or a lower-court order affects the analysis;
whether the necessary point can be made without revealing the communication; and
whether in camera treatment or another narrower procedure is available.
Marking a privileged document “Under Seal” is not a substitute for that analysis. Sealed filing ordinarily still gives the Court—and potentially parties authorized under the service or protective regime—access to the material.
If privilege was rejected below and disclosure is imminent, the company may need emergency relief before the information is produced. Once an adversary or the public learns the substance, later appellate relief may not restore secrecy.
Trade Secrets and Commercial Information Require a Particularized Showing
Companies frequently seek protection for:
source code and system architecture;
customer or patient information;
nonpublic pricing and margins;
formulas, processes, and technical specifications;
product-development plans;
unreleased financial information;
acquisition or transaction terms;
internal risk analyses;
vendor contracts;
cybersecurity details;
employee compensation; and
member or donor information.
The sealing motion should not rely only on the label “trade secret” or “confidential.” It should explain, without revealing the secret itself:
what category of information is involved;
how narrowly the proposed seal is drawn;
whether the information remains nonpublic;
what measures the company uses to protect it;
how disclosure could cause concrete competitive, commercial, security, or privacy harm;
why older information still requires protection;
why redaction alone is or is not sufficient; and
why the Court needs the material.
Where the lower court already made findings, cite and provide the sealing order. If no sealing was sought below, the motion must confront why first-instance protection is justified now.
Audit Every Filing Component, Not Just the Brief’s Argument
Sensitive information can appear in unexpected places:
Questions Presented;
list of parties and corporate disclosures;
procedural history;
quoted lower-court opinions;
record citations;
appendix captions and docket sheets;
orders denying rehearing;
transcript headers;
exhibit labels;
declarations;
amicus descriptions;
certificates of service;
proof-of-service recipient lists;
hyperlinks;
embedded attachments; and
PDF metadata or hidden text layers.
The appendix often presents the greatest risk because Rule 14 may require opinions and orders that themselves reproduce confidential information. Counsel should identify the protected passages early enough to prepare coherent public and sealed versions without breaking pagination or citations.
Redaction must remove the underlying data, not merely place a black box over visible text. Public files should be tested by copying text, searching, reviewing accessibility layers, examining bookmarks, and checking extracted images before printing or distribution.
Coordinate With Other Parties, Nonparties, and the Lower-Court Clerk
Confidentiality interests may belong to someone other than the filer. A contract counterparty, customer, employee, insurer, association member, expert, government agency, or nonparty may have rights or obligations affected by the filing.
The company should identify:
every protective or sealing order;
who designated the material;
who has authority to consent to public use;
whether notice is required before challenging or changing a designation;
whether the other side disputes continued sealing;
whether a nonparty needs an opportunity to be heard;
which record volumes or exhibits are sealed below; and
how the lower-court clerk will transmit sealed parts of the record.
Rule 34.7 requires the motion to report the parties’ positions. Conferral should occur early enough to narrow disputes and avoid emergency motion practice on the filing date.
Certiorari-Stage Strategy
At the petition stage, the company must balance Rule 14’s appendix requirements against confidentiality.
A practical sequence is:
calculate the jurisdictional certiorari deadline;
identify every mandatory appendix item;
map sealed or sensitive passages within those items;
determine what can be publicly redacted under Rule 34.6 or by motion;
isolate sealed material into a supplemental appendix where possible;
prepare the Rule 34.7 motion and public version;
obtain the other parties’ positions;
coordinate paper filing, service, and printing; and
verify that nothing in the package is submitted electronically.
A sealing motion does not extend the time to file a petition. The certiorari deadline, a Rule 13.5 extension application, and any stay request must be managed separately.
Merits-Stage and Joint-Appendix Strategy
After certiorari is granted, Rule 26 joint-appendix designations begin quickly. If the parties do not agree, the petitioner ordinarily serves its designation within 10 days after the grant, and the respondent may designate additional material within 10 days after receiving it.
Counsel should decide whether sensitive material truly belongs in the joint appendix. Because the full record is available to the Justices, citation to a sealed record volume may sometimes avoid unnecessary republication. If sealed material must appear in the appendix, Rule 34.7 calls for a separate supplemental volume.
Merits briefs also require close coordination with amici. An amicus may not know that a document or fact remains sealed. The party should provide public source boundaries and warn amici against reproducing protected party-specific material. Rule 37 disclosure and independence requirements still apply.
Emergency Applications and Irreversible Disclosure
If a lower court orders imminent disclosure of privilege, trade secrets, source code, personal data, or sealed materials, an ordinary certiorari schedule may come too late. The company may need a stay or administrative stay while seeking review.
Under Supreme Court Rule 23, a stay applicant ordinarily must seek relief first in the appropriate lower court or courts and explain with particularity why relief is unavailable there. The application should establish:
the precise disclosure deadline;
the protected nature of the material;
the irreparable harm from disclosure;
the likelihood of success and reviewability;
why narrower protections are inadequate; and
the requested duration and scope of relief.
An emergency filing that itself reveals the protected information defeats its purpose. The Rule 34.7 and paper-only procedures should be incorporated into the emergency plan.
Deadlines and Procedural Timing
Certiorari petition: ordinarily due within 90 days under Rule 13, subject to rehearing rules and any timely Rule 13.5 extension.
Brief in opposition: generally due 30 days after docketing under Rule 15, unless waived, called for, or extended under the applicable procedure.
Merits filings: governed by Rule 25 and any case-specific schedule.
Joint appendix: ordinarily due 45 days after the grant; designations may begin within 10 days under Rule 26.
Response to a motion: ordinarily due within 10 days of receipt under Rule 21.4 unless the Court, a Justice, or the Clerk orders otherwise.
Disclosure order: may require a stay on a much shorter schedule than any merits filing.
No party should assume that a sealing motion tolls a jurisdictional or briefing deadline. Confidentiality and deadline plans must run in parallel.
Risks and Appeal Consequences
Immediate public posting: An electronic submission may be publicly accessible before staff review.
Privilege waiver: Sealing may not prevent waiver or adversary access.
Overbroad request: Seeking to seal entire filings can weaken a motion that could have been narrowed.
Underinclusive redaction: Sensitive information may remain in a caption, table, metadata field, or hidden PDF layer.
Inconsistent versions: Public and sealed copies may have different pagination, citations, or text beyond the authorized redactions.
Unsupported confidentiality: A designation or protective order may not establish continued necessity in the Supreme Court.
Record problem: Material not properly part of the lower-court record generally cannot be added through a sealed appendix.
Missed deadline: A sealing dispute does not excuse an untimely petition or brief.
Operational harm: Disclosure may affect competition, cybersecurity, customers, regulators, employees, or transactions.
Public-access challenge: Another party, media organization, or interested person may contest sealing.
Later unsealing: Rule 34.7 requires prompt notice if continued sealing is no longer necessary.

Stay protection: 28 U.S.C. § 2101(f) and Supreme Court Rules 22 and 23 govern potential relief against enforcement or disclosure while Supreme Court review is pursued.
Sealing, privilege, waiver, trade-secret protection, and privacy depend on the specific information, lower-court orders, governing law, filing stage, and current Court procedures. This article provides general information, not legal advice.
Why Appellate-Aware Confidentiality Strategy Matters
Supreme Court confidentiality is usually determined by work done much earlier. Trial and appellate counsel must create a supportable sealing record, obtain findings, preserve privilege, define protected material narrowly, seek a stay before disclosure, and prepare public and sealed versions that remain usable on review.
Biazzo Law brings an appellate-aware litigation perspective across Florida and North Carolina courts, federal district courts, the Eleventh and Fourth Circuits, and the U.S. Supreme Court. That coverage connects protective orders, privilege review, trade-secret evidence, sealing motions, appellate records, certiorari appendices, emergency injunction readiness, and merits-stage planning.
The firm’s Supreme Court and amicus lens also helps companies and organizations coordinate public-facing advocacy without exposing information that should remain protected. Amici can explain industry or institutional consequences, but they should not inadvertently republish confidential party materials or undermine a sealing position.
Frequently Asked Questions
Does a lower-court sealing order automatically remain effective in the Supreme Court?
No. The order is important evidence, but Rule 34.7 requires a motion addressing the lower-court seal, its continuing effect, the original reasons, and why confidentiality remains necessary in the Supreme Court.
Can a petition with sealed material be filed electronically?
No under the Court’s March 2026 guidance. A filing containing sealed material—and associated public or redacted documents—should be submitted only in paper form and should not be served electronically.
Is a motion required for Social Security numbers and other mandatory personal-identifier redactions?
No. The electronic-filing guidelines state that no motion is required for redactions mandated by Rule 34.6. Additional redactions may require an appropriate motion.
Does filing a privileged document under seal prevent waiver?
Not necessarily. Sealing restricts public access; it does not automatically preserve attorney-client privilege or work-product protection. Waiver, ownership, service, disclosure, and subject-matter consequences require a separate analysis.
Must the company provide a public redacted version?
Where possible, Rule 34.7 says the movant should provide one. If a public version is not feasible, the motion should explain why.
How should sealed material in a petition appendix be organized?
Rule 34.7 says sealed appendix material should be presented in a separate supplemental volume. The cover and every page should be marked “Under Seal,” while the public version should use the prescribed redaction legend.
Can the company seal information that was public below?
The company may request first-instance sealing, but the motion must explain with specificity why sealing is necessary now. Prior public availability can substantially weaken the claim that confidentiality remains protectable.
What should a company do if disclosure will occur before a certiorari petition can be decided?
Evaluate an immediate stay or administrative stay. Relief ordinarily should be sought first in the appropriate lower court, and any Supreme Court application must address reviewability, irreparable harm, likelihood of success, equities, and why narrower protection is inadequate.
