Chapter 10 answers

U.S. Const. art. III, § 1. U.S. Const. identifies the federal Constitution, art. III identifies the article, and § 1 locates its section. The inspected National Archives transcription supplies the provision. The ordinary current-provision format does not add the retrieval year. The citation demonstrates a locator, not the resolution of every constitutional-jurisdiction question.

The source is a constitution rather than a reported judicial interpretation. Its organizational units are article and section, so those units supply the pinpoint. Article III is not a case volume, and section 1 is not a page. An access date can be retained internally without becoming a constitutional enactment or publication date in the model.

Do not add (2026) merely because you opened the National Archives transcription then. That could suggest a temporal version the citation does not intend to identify.

Follow article III to section 1 in the supplied source. Confirm the sentence describes that text rather than an unresearched constitutional holding.

17 U.S.C. § 107(1) (2024). Title 17 and U.S.C. identify the federal code, and (1) selects the first numbered fair-use factor. The parenthetical preserves the inspected edition for this historical teaching example. It is not a statement that all citations to current federal provisions require a year or that amendments through 2026 were checked.

The nested parenthetical (1) is part of the section address. It directs the reader to a particular factor rather than all of § 107. The historical edition label tells the reader which source was inspected. Choosing that explicit version is different from claiming that every current United States Code citation must always carry a year.

Do not replace (1) with at 1 or cite § 1071. Those alterations change the locator structure rather than abbreviate it.

Read title 17, section 107, factor 1, and edition 2024 as separate fields; locate the same factor in the saved source.

The inspected 2024 Code includes the purpose and character of the use, including educational or commercial character, among the fair-use factors. 17 U.S.C. § 107(1) (2024). The source does not make all educational copying automatically lawful. Preserve the narrow factor-listing proposition and analyze an actual use under the relevant facts and law before stating a conclusion about it.

A listed factor identifies something the statute directs consideration of; it does not mechanically decide every application involving that factor. The claim must remain as narrow as the inspected passage. The repair retains the useful statutory information while removing the categorical conclusion about all educational copying, which the source does not provide.

Do not hide the same overstatement in a parenthetical such as (making educational copying lawful). A parenthetical must be supported just as the main sentence must be.

Ask whether the sentence claims a factor exists or announces the result of every case. Only the former is supported here.

Enactment identifies when legislation became law; effective date identifies when a provision operates; edition date identifies a publication/version; retrieval identifies access. These can differ and should be separate research fields. The date used in a citation depends on the source-specific rule and historical/current purpose. Do not convert the most recent access timestamp into a legislative or publication date.

The dates describe different events, so they belong in different source-card fields before you choose a citation form. Enactment can precede effectiveness; publication can collect existing law; retrieval can occur years later. A historical application may require the effective or transition provision, while the citation's parenthetical identifies the actual publication version consulted.

Do not choose the newest date simply because it appears most current. The newest access date may tell you nothing about the rule governing an earlier event.

Label each date with the event it records. If you cannot name that event, investigate before assigning the date to a citation.

Retrieve the version applicable to the 2020 event and inspect its text and amendment/effective-date history. The 2026 display alone cannot prove what the provision said or how it applied in 2020. Record the actual historical source and any uncertainty. Do not guess the old wording from the present text or assume the 2022 change operated retroactively.

The problem gives three times but not the change's operative reach. Obtain the pre-change text, the amending instrument, and its effective or transition provisions. Compare the passage relevant to the 2020 conduct. Only that comparison can justify using a historical version or explain why some later provision also matters to the dated issue.

Do not assume the 2022 amendment applied backward or assume it could never affect earlier matters. Either conclusion needs the actual operative language and relevant legal analysis.

Can you show the exact 2020 wording and the source establishing the amendment's temporal reach? If either is missing, keep applicability unresolved.

No. The publisher's note is editorial commentary distinct from the enacted text. Identify it as such if citing its explanation, and research the actual authority establishing any exception. A code's annotations can be useful research leads without being legislative commands. Preserve the contributor and source role instead of attaching the note's statement to the statute as though enacted.

An annotated publication combines legal text with publisher contributions. The visual proximity of a note to the section does not give the note the legislature's authorship. If the note cites a case, read that case's relevant passage before presenting the proposed exception as law. The annotation can guide research while remaining a separately attributed explanation.

Do not cite only the code section after repeating the publisher's exception. That incorrectly sends the reader to statutory words that do not contain it.

Find the claimed exception in the cited source itself. If it appears only in editorial material, preserve that attribution and trace its authority.

Harbor Code tit. 8, § 20(b) (2025). The supplied title, code, section, subsection, and edition identify this invented source precisely. Equivalent clear fictional formatting can be acceptable under a supplied local instruction, but do not omit subsection (b). The locator does not refer to §§ 20–21 or to a separately numbered chapter.

The invented compilation uses a title plus a section with a lettered subdivision. The citation therefore retains both the title and (b), rather than shortening to a naked section that could occur elsewhere. The parenthetical identifies the supplied 2025 edition. The model teaches address construction, not a conclusion about a real jurisdiction's enacted law.

Do not use § 20(b)(2025) as though the year were another statutory subdivision. Separate the edition parenthetical from the section's attached nesting.

Match each field to the packet: Harbor Code, title 8, section 20, subsection b, edition 2025. Keep the fictional label with an independent copy.

Session laws can identify an enactment, uncodified provision, amendment, or historical text in its enacted form. A current code organizes operative provisions differently and may omit uncodified material. Choose the source matching the proposition. The difference is research purpose and organization, not a claim that one format is always better or that every statute needs both citations.

The source should match the legal event being described. A session law preserves an enactment's own organization, including uncodified and transition provisions. A code organizes selected operative text under its subject structure. The relevant question is where the proposition appears, not which publication sounds newer or contains a more familiar abbreviation.

Do not invent a code section for an uncodified provision. A blank code field is a research fact, not an invitation to supply a plausible number.

Open the cited source at the actual provision. Does it contain the enacted wording or effective-date clause the sentence discusses?

Retain the distinguishing title/code information because section 12 appears in more than one cited source. Use the relevant source-specific short form or repeat the full citation when necessary. A naked section reference is useful only when the context makes its source unambiguous. The author's memory of which code was intended cannot supply missing reader-facing identification.

Short forms depend on the document's context, not merely on a section number being brief. Two different titles can each contain § 12. Preserve the title or fuller code identity needed to select one. If a reader could reasonably choose either source, restore the distinguishing information even though the writer personally remembers the intended referent.

Do not use Id. to jump back across another title's citation. Immediate-reference rules and ambiguous section numbers create separate potential errors.

Hide your research notes and follow the short form from the preceding text. There should be exactly one recoverable title and section.
