Build a citation you can explain

Opening problem

You find an Illinois Supreme Court opinion online. It has numbered paragraphs, a court-assigned designation, and a regional-reporter citation. You cannot decide whether to use a reporter page, the PDF page, or a paragraph. The answer begins with the court's citation system and the requirements of your receiving document.

Learning objectives

Distinguish reporter citations from neutral citations; identify paragraph pinpoints; recognize local requirements; construct database and slip-opinion patterns from supplied metadata; and separate citation permission from precedential force.

One country, several systems

State citation practice is not a single uniform format. A jurisdiction may prefer its official reporter, allow a regional reporter, require parallel citations, place the year differently, or assign a neutral identifier. The state reference tables provide an orientation to variation. Edition-era notes are not a current fifty-state rule survey.

A neutral citation uses information assigned independently of a publisher's reporter pagination. Systems differ: the year, court abbreviation, sequential or docket-derived number, and paragraph locator may appear in different arrangements. A court-assigned case identifier is not itself a pinpoint. Paragraph 1 is a location within the identified decision.

Annotated Illinois model

People v. Clark, 2016 IL 118845, ¶ 1.

The first paragraph states that the court affirms the appellate court's judgment. Use ¶ 1 for that historical disposition. A sentence about the reasons for affirmance would require the paragraphs explaining those reasons, not merely this introductory result.

Illinois Supreme Court Rule 6 requires the public-domain citation for Illinois cases filed on or after July 1, 2011, and for the specified earlier unpublished cases assigned such a citation; appropriate pinpoints use paragraph numbers. A regional-reporter or Illinois Decisions citation may be added. Earlier officially reported Illinois cases have a different reporter requirement. Read the rule's applicability language before translating “Illinois uses neutral citations” into a rule about every Illinois case ever decided.

Rule 6 answers the format question. Separate briefing rules and rules governing unpublished orders may answer other questions about the document or the authority. Do not make the optional parallel citation mandatory or infer precedential force from the citation form.

Reporter and paragraph pinpoints are not interchangeable

A parallel reporter citation identifies the same decision in another publication. Its page pinpoint must locate the same passage as the paragraph pinpoint. Do not append a regional page merely because the database displays a first page. If you have checked only paragraph 1, you have verified paragraph 1. A regional pinpoint remains unchecked until you inspect its pagination.

Likewise, page 3 of a downloaded PDF may not be reporter page 3 or numbered paragraph 3. PDF pages count file sheets. Reporter pages and opinion paragraphs are source locators. Record all three separately if your workflow needs them, and use the locator the citation system requires.

Unreported, unpublished, and nonprecedential

These terms describe different attributes. An opinion may lack a bound reporter citation yet be precedential. It may appear in a database while being designated nonprecedential. An order may have a neutral identifier with a special suffix. Do not infer legal weight solely from the format in which you discovered it.

Federal Rule of Appellate Procedure 32.1(a) addresses restrictions on citing certain federal judicial dispositions designated unpublished or nonprecedential and issued on or after January 1, 2007. Its scope concerns citation restrictions; it does not assign precedential weight to those dispositions. Subsection (b) addresses providing a copy when the disposition is not available in a publicly accessible electronic database. Verify the rule and the receiving circuit's rules when using this material. State restrictions require their own inquiry.

The online status “available” also requires care. Available through your paid account is not necessarily available in a publicly accessible database. If a rule requires a copy, supply the actual disposition with the required filing and service treatment. A citation to a search-result page does not satisfy a copy requirement by itself.

Database decisions

A database citation often needs the case name, docket number, year/database/document identifier, a star-page pinpoint, court, and full decision date. The database identifier is a document number, not a reporter volume. A star-page locator points into that database's pagination. Preserve the asterisk when the source uses it.

Fictional training example — not legal authority. Supplied metadata: Vale v. Harbor, docket 24-100, 2025 Fiction DB 900, star page 4, fictional Harbor Court of Appeals, June 2, 2025. A training pattern is Vale v. Harbor, No. 24-100, 2025 Fiction DB 900, at *4 (Harbor Ct. App. June 2, 2025). “Fiction DB” and “Harbor Ct. App.” are training labels, not real reporters or courts. The pattern teaches field order without inventing a real holding.

For a real source, use its actual database abbreviation and identifier, the correct court/date, and the receiving court's approved format. A free database's cluster identifier should not automatically be converted into a commercial database citation. CourtListener's web address supplies access to the opinion; its numeric URL component is not a Westlaw or Lexis identifier.

Slip opinions

A slip opinion is an opinion issued before or apart from a bound reporter version. Its citation may use the docket number, slip-opinion page, court/date, and an access URL. Check for a superseding official version before finalizing. If the published version has different pagination, replace the locator with the appropriate published pinpoint rather than preserving an obsolete slip page.

Where an official electronic opinion reproduces conventional reporter information accurately, cite the underlying case under its normal source rule. Do not turn every downloadable case into a website citation. Electronic delivery and legal source classification are different questions.

A local-rule check you can repeat

Begin with a precise question: “For this opinion, in this document, must I use a reporter, a neutral designation, or both?” Identify the receiving court and its applicable rules, standing orders, and incorporated manual. Read the applicability language as closely as the model citation. A requirement may depend on the opinion's date, the issuing court, or the document being filed.

Keep the controlling instruction with the resulting citation choice. Record its effective date separately from the day you opened the page. If a court incorporates a particular manual edition, a newer commercial edition does not automatically displace that instruction. An old reference table can help you find the issue; the applicable receiving instruction decides the format.

Common mistakes and repairs

Compact reference

Reporter → pages. Neutral identifier → system-specific paragraphs where provided. Database identifier → database pinpoints. Slip opinion → slip pages. Receiving-court requirements can change the choice or combination. A locator never proves legal weight.

Worked editing session: document a local-rule decision

Apply the Illinois rule to Clark's supplied identity: a 2016 Illinois Supreme Court opinion with a public-domain citation and numbered paragraphs. Its date falls after the rule's July 1, 2011 cutoff. The citation route is therefore the assigned designation with the paragraph pinpoint. An optional reporter citation adds another address; it does not replace that required route.

The result is People v. Clark, 2016 IL 118845, ¶ 1. You reached it by applying the date condition and the locator rule, not by copying a similar-looking state citation.

Fictional training example — not legal authority. A different court's supplied instruction requires a neutral citation and paragraph pinpoints, while allowing an optional reporter citation. The opinion passage is ¶ 14; a search result supplies only the reporter's first page. Use the required paragraph route now. Add a reporter pinpoint only after finding the corresponding page. An optional field should not become an invitation to guess.

If you cannot obtain the governing instruction, the missing information is specific: you do not yet know which route the receiving court requires. Search the court's current official rules page and any incorporated instructions. Keep working on the opinion's identity and passage, but leave the unresolved format choice visible until that text is available.

Preserve the complete neutral identifier

An identifier's suffix or court segment can distinguish versions and court levels. Illinois Rule 6's commentary explains the appellate district segment, sequential letters for later opinions under the same docket, and the U suffix for Rule 23 orders. Copy the designation assigned to the source. Do not strip a suffix as though it were a database artifact. A correct paragraph number attached to the wrong designation can lead to another disposition.

The date limit in FRAP 32.1(a) concerns its restriction on rules forbidding citation of the covered dispositions. The separate copy requirement in subsection (b) is not limited by that same 2007 date or the listed nonprecedential labels: it addresses cited federal written dispositions unavailable in a publicly accessible electronic database. Read the two subdivisions separately. Their shared rule number does not give them identical coverage.

Build a version map before replacing a citation

Fictional training example — not legal authority. A court issues an opinion on June 2 with the relevant passage at slip page 4. On June 9 it issues a corrected opinion moving that passage to page 5 and changing a material qualification. Your draft still quotes the June 2 wording and cites page 4. The repair has two parts: decide which version supplies the proposition, then update both wording and locator to that version. Substituting page 5 without comparing the text leaves the quotation wrong.

Make a version map with separate fields for release date, designation, text revision, and pagination. A later upload timestamp may reflect a website migration without a new opinion. A corrected opinion may retain much of the identifier while changing the relevant words. A reporter publication may preserve the decision but add stable pagination. Use the document's own revision information and actual comparison to distinguish those events.

If the argument concerns what an earlier version said, identify that historical purpose expressly and preserve the earlier source. If the argument relies on the court's operative opinion, locate the superseding source and its actual passage. Do not attach the new publication's citation to language found only in a withdrawn text. This problem can survive metadata validation because both documents may share the same parties, docket, and decision year.

A slip-opinion citation requires actual source metadata. Under the slip-opinion baseline the basic order is case name, docket number, slip op. at the supplied page, court and full date, and the source URL. A viewer page is not automatically a slip-opinion page. If the official document supplies numbered opinion paragraphs instead, check the applicable system and use those locators. An online link is valuable access information but does not supply missing court, date, or opinion identity by itself.

Source laboratory: two Rule 32.1 provisions answer different questions

The Federal Circuit's official compilation places Federal Rule of Appellate Procedure 32.1 beside Federal Circuit Rule 32.1. The repeated number can mislead a hurried reader. The federal rule limits restrictions on citing covered federal dispositions and supplies a copy requirement. The circuit rule addresses the receiving court's treatment of nonprecedential opinions. They are separate texts with different jobs.

Read Federal Circuit Rule 32.1(d), in the compilation dated October 6, 2026. It permits the court to look to nonprecedential or unpublished dispositions for guidance or persuasive reasoning, while withholding binding effect from its own nonprecedential dispositions. It addresses other courts' dispositions by reference to those courts' rules. That is a concrete local answer to the weight question left open by the general citation-permission rule. It does not turn every cited disposition into binding precedent.

A research note can now make three bounded decisions. Citation permission: inspect federal Rule 32.1(a), including its designations and January 1, 2007 date. Access: inspect subsection (b) and determine whether a public electronic copy exists. Weight in this receiving court: inspect the separate circuit provision. Record which Rule 32.1 you mean each time; a bare “Rule 32.1 checked” loses the distinction.

This is also a version lesson. An official URL can deliver an old compilation. Check its cover date and relevant rule text rather than assuming “official website” means “latest file.” A historical source can remain useful while its temporal coverage remains limited. Keep the authority's decision date, the compilation's date, and your retrieval date in separate fields.

Takeaway

Choose the locator belonging to the source's citation system, then check the receiving court's rules. Format, availability, and precedential force are separate questions.
