Research methodology

How each guide is researched and updated

Methodology current September 26, 2026

EO Explained follows an order from its signed text through later agency action, presidential changes and court proceedings. The aim is to show what the order directed, what happened next and what the cited authorities support on the page’s last-checked date.

Research workflow

1

Read the controlling text

We begin with the signed presidential action and its Federal Register publication. We record what it directs, who must act and any express deadline.

2

Trace implementation

We look for agency rules, memoranda, guidance, official datasets and later presidential actions. A direction is not described as completed until an authoritative source supports that conclusion.

3

Check later legal events

We check later orders, statutes and relevant court records. Interim rulings are described as interim; a stay is not presented as a final judgment on the merits.

4

Separate claim from fact

Policy rationales, projected benefits and evaluative language are attributed to the speaker. Verifiable actions and court holdings are stated separately.

Illustrative example

From instruction to dated status

This example is fictional. It shows the editorial decisions; it is not an executive-order record.

  1. Order text: “The agency shall submit a report within 60 days.” We can report the instruction and deadline, but not that the report was completed.
  2. Agency record: The agency publishes a dated report. We can then say the instruction was implemented, linking the report.
  3. Court record: A lawsuit challenges one implementing rule. We identify the case and the ruling’s scope; we do not describe the entire order as blocked unless the authority supports that conclusion.
  4. Guide wording: Administration claims remain attributed. The status note states what is known, the sources supporting it and when that position was last checked.

Source hierarchy

  1. Signed presidential action and Federal Register publication
  2. Statutes, regulations and official court records
  3. Agency implementation material and government data
  4. Non-government reporting or analysis when it adds necessary context

Order pages group primary and official material separately from background sources. Background material can explain context, but it does not replace controlling authority. Authority labels repeat statutes or other legal bases identified in the cited analysis; they are not an independent or exhaustive judgment about presidential authority. See the source library for the source labels used throughout the site.

Research levels and status labels

Extended evidence review

What has been checked

The official text, responsible agencies, deadlines, implementation, later presidential action and relevant litigation have received a source-led editorial review.

Official text checked

What has been checked

The official document and core metadata are verified. Later implementation and litigation have not yet received the same full review, so the page does not imply a substantive current position.

A research level describes the depth of editorial review. It is not a legal-status judgment. Status labels are dated summaries of the featured order or policy and must be read with the page’s scope note and sources. Read the full status guide.

Updates, uncertainty and corrections

  • Each order page shows when its official record or full legal and implementation position was last checked.
  • If sources conflict or a proceeding is unresolved, the guide states the uncertainty instead of predicting an outcome.
  • A narrow ruling is not generalized beyond the measure, parties or period supported by the cited authority.
  • A material factual correction is recorded separately from navigation, labeling and other editorial changes.

See the public corrections and editorial changes log for the distinction and recorded history.

Historic orders before 1993

The historic collection selects twenty landmark orders; it is not a complete run. For pre-1993 orders we use original Federal Register records where available, National Archives disposition information, presidential-library holdings and official court decisions. The disposition tables stop updating at 2017, so later status needs separate dated evidence. Orders issued before the Federal Register began in 1936 require archival originals or faithful scans and a clear explanation of any retroactive numbering.

Orders before the Federal Register

For pre-1936 orders we prefer a National Archives catalog record, a presidential-library or Library of Congress holding, a government reproduction of the original, or a faithful archival scan. Institutional text transcriptions help readers inspect the wording but are labeled separately from a government original. The State Department began numbering its collection in 1907 and applied numbers to earlier orders in its files; some genuine orders were unnumbered. We therefore check document type and date before assigning a route.

Saved copies and original publishers

If a source link has moved, try the saved-copy link beside it. Archived copies are third-party snapshots; the cited publisher remains the authority.

How sources are ranked

We prefer the signed order and Federal Register text, then agency implementation material and court opinions or dockets. Background reporting or analysis is listed separately and does not replace controlling authority.
