Using the real U.N. Charter model above, explain what article 2 and paragraph 4 identify. State why a citation to the provision alone does not resolve every application of the law governing force.
- A sound answer
U.N. Charter art. 2, ¶ 4 identifies paragraph 4 within article 2 of the Charter. The locator directs the reader to the provision addressing members’ threat or use of force in international relations in its stated terms.
- Why it works
The citation identifies an instrument and subdivision; it does not supply an analysis of every possible use of force. A broader argument needs the provision’s full text, surrounding framework, relevant interpretations, and the facts of the particular problem. The chapter uses this as a source-location model rather than a complete treatment of substantive international law.
- A tempting mistake
Treating the provision number as a self-executing answer to every factual situation skips interpretation and application. A more elaborate citation would not eliminate that analytical work. Conversely, the provision should not become a generic webpage merely because its text was accessed online.
- Check your work
Does the answer distinguish what the locator identifies from what additional legal reasoning would be needed for a broader application?

Fictional training example — not legal authority. The Harbor Access Treaty was signed January 4, 2024 and entered into force for Bay State on September 1, 2025. A dispute concerns March 2025. Identify the error in saying that signature alone proves the treaty was already in force for Bay State.
- A sound answer
Fictional training example — not legal authority.
The supplied dates show signature on January 4, 2024 and entry into force for Bay State on September 1, 2025. They do not establish that the treaty was already in force for Bay State during March 2025; the supplied entry-into-force date is later.
- Why it works
Signature and entry into force describe different events. A proposition about a state’s obligations at a particular time requires the relevant status information and, where material, the instrument’s terms. This closed packet gives a specific later date and no provisional-application arrangement or other basis for the draft’s claim.
- A tempting mistake
Do not infer early operation from signature or invent a reservation, provisional application, or customary-law argument to save the sentence. Those could be separate research questions in a real matter, but they are not supplied answers here.
- Check your work
Does the corrected account preserve both event labels and compare March 2025 with September 1 without treating the signature date as a substitute?

Use the Chagos model and supplied paragraph description. Write a historical sentence identifying the Court's 2019 conclusion and the opinion's advisory character. Explain why the sentence should not assert present implementation without additional sources.
- A sound answer
“In its 2019 advisory opinion, the International Court of Justice concluded that the United Kingdom was obliged to end its administration of the Chagos Archipelago as rapidly as possible.” Legal Consequences of the Separation of the Chagos Archipelago from Mauritius in 1965, Advisory Opinion, General List No. 169, ¶ 178 (I.C.J. Feb. 25, 2019), https://www.icj-cij.org/node/105778.
- Why it works
The sentence reports the historical conclusion supplied in paragraph 178 and identifies the proceeding as advisory. The citation preserves the decision’s institutional identity and precise paragraph. Its official English text is the inspected model; the chapter separately records the opinion’s authoritative-language statement.
- A tempting mistake
Do not replace “concluded in 2019” with a claim about present implementation or contemporary arrangements. Those events require later sources. Likewise, omitting “Advisory Opinion” conceals the legal role being taught.
- Check your work
Does the sentence describe the inspected 2019 conclusion, and does it avoid announcing later compliance or implementation from that opinion alone?

Fictional training example — not legal authority. On an international court's site, a party submission at paragraph 44 requests closure, while the interim order at paragraph 19 requires reporting. Repair “The Court ordered closure, ¶ 44” and identify the proper source for each proposition.
- A sound answer
Fictional training example — not legal authority.
“The interim order requires reporting.” Cite the court’s interim order at paragraph 19. Separately: “The party requested closure.” Cite that party’s submission at paragraph 44.
- Why it works
A common institutional website hosts distinct documents by distinct speakers. The party’s requested remedy is not the tribunal’s disposition. The proper repair changes both the verb and the source locator, separating the request from the order. The packet supplies no complete titles or dates for fuller citations, so the answer should not invent them.
- A tempting mistake
Keeping “the Court ordered closure” and changing only 44 to 19 still reverses the supplied order’s substance. Calling the party submission an opinion because it is hosted on the court’s site makes the same classification error in another form.

Do the two sentences identify different actors, and does each locator lead to the document that supplies that actor’s action?

Fictional training example — not legal authority. Bay Union Assembly Resolution 18/2025, adopted June 2, 2025, contains a preamble and an annex entitled Access Principles. Annex article 3 is the relevant passage. Build a descriptive citation preserving the organ, resolution number, adopted date, annex title, and article. No standardized abbreviation is supplied or required.
- A sound answer
Fictional training example — not legal authority.
Bay Union Assembly Resolution 18/2025, annex, Access Principles, art. 3 (June 2, 2025).
- Why it works
The descriptive form preserves the issuing organ, instrument number, adopted date, annex title, and internal article. The relevant passage is in the annex, so citing only the resolution as a whole would be less precise. The date records adoption as supplied; it is not inferred from the website or resolution number. No standardized abbreviation is needed when the packet supplies none.
- A tempting mistake
Do not cite a preambular paragraph as the source of annex article 3 or omit the Assembly in favor of the broader organization alone. Also avoid inventing a document symbol, series, or reporter to make the citation look more familiar.
- Check your work
Can the reader distinguish this organ’s resolution from another Bay Union document and locate article 3 of the named annex?
- Alternatives
Placing the annex title and article after the parenthetical date is acceptable in a consistent descriptive house style if the source hierarchy remains clear.

Fictional training example — not legal authority. A treaty webpage contains an authentic French text and an English rendering explicitly labeled unofficial. Your quotation comes from the English rendering. Identify the language and status that should be disclosed and the additional work needed if meaning turns on a disputed word.
- A sound answer
Fictional training example — not legal authority.
Identify the quotation as taken from the unofficial English rendering, and identify its translator or source when supplied. Record that the treaty page labels the French text authentic. If the interpretation depends on a disputed word, obtain and analyze the authentic French passage and a defensible translation account before making the legal claim.
- Why it works
The language used for convenience and the language’s legal status are separate facts. A fluent English rendering does not become authentic merely because an official site hosts it. The citation and prose should allow the reader to evaluate the wording actually quoted.
- A tempting mistake
Do not silently quote the English text while describing it as the treaty’s authentic language. Do not invent a translator, certification, or resolution of the disputed term. A label discloses the limitation; it does not itself solve the interpretive question.
- Check your work
Does the reader know which wording was inspected, which language is authentic, and what interpretive work remains if the disputed word matters?

The EDPB source described above lists adoption and publication dates and separate corrigendum and consolidation links. Explain why those records should not be collapsed into one undifferentiated “2016 version” field.
- A sound answer
Keep separate fields for adoption, Official Journal publication, correction, and the particular consolidated display. The EDPB page identifies adoption on April 27, 2016 and publication on May 4, 2016, with separate links for a corrigendum and consolidation.
- Why it works
Those records describe different events or documentary objects. A claim about enactment history may use the adoption and publication information; a quotation from revised text may require the correction and the exact consolidated version inspected. The label “2016 version” does not show which object supplied the words or whether a correction affects them.
- A tempting mistake
Do not assume that every consolidation is the authentic act, or that the original publication necessarily contains wording introduced by a later correction. Read the repository’s status notice and inspect the actual passage needed for the claim.
- Check your work
Could another researcher identify the precise text quoted and distinguish it from the original publication and separate correction record using your source card?

Fictional training example — not legal authority. A secretariat report, Document BU/S/2025/17, recommends quarterly reporting at paragraph 28. The assembly has not adopted the recommendation in the supplied packet. Repair “Bay Union law requires quarterly reporting” and provide a source-specific descriptive reference.
- A sound answer
Fictional training example — not legal authority.
“The secretariat recommends quarterly reporting.” Bay Union Secretariat, Report, Document BU/S/2025/17, ¶ 28.
- Why it works
The packet identifies an institutional report, its symbol, its recommendation, and its paragraph. It expressly supplies no Assembly adoption. The repair therefore attributes the recommendation to the secretariat instead of declaring an enacted requirement. A fuller descriptive title or date could be added if actually supplied, but should not be invented here.
- A tempting mistake
Changing the citation from a homepage to a document symbol while retaining “law requires” leaves the substantive error intact. The source’s official institutional status does not make every recommendation legally binding. A later adoption would be a separate source requiring inspection.
- Check your work
Does the sentence’s subject name the secretariat, its verb remain “recommends,” and its locator identify paragraph 28 without implying that the Assembly adopted it?

Fictional training example — not legal authority. You verified an official landing page's title and date, but the linked judgment failed to open. Write a research note accurately distinguishing metadata verification from passage and legal-effect verification. Identify a suitable next retrieval step without claiming that it already occurred.
- A sound answer
Fictional training example — not legal authority.
“Metadata checked: the official landing page identifies the judgment’s title and date. The linked judgment did not open. No passage, reasoning, disposition, or legal-effect claim has been verified from the judgment text. Next step: seek an accessible official copy through the court’s document collection or alternate official link, then compare identity and inspect the relevant passage.”
- Why it works
This note records completed work and a failed retrieval separately. The landing page can supply bibliographic facts while leaving the substantive source unread. An alternate copy must still be matched to the intended judgment, especially where a case page contains several orders or separate opinions.
- A tempting mistake
Do not mark the judgment “read” because the title was visible. Do not say an alternate official copy was obtained when that is merely the proposed next step. The research note should be reproducible from actual actions.
- Check your work
Can another researcher distinguish the verified fields, the inaccessible document, and the unperformed retrieval and proposition checks?
