The Gibsonian Canons of Constitutional Interpretation

The framework

Most computational law starts too late: it formalizes rules produced by an interpretive method that was never written down. The Gibsonian Canons start one level earlier. They are a thought experiment set on Gibsonia, a fictional planet in the Guitaria system, and they ask what an interpretive method would look like if it had to be chosen before anyone knew who would interpret, which disputes would arise, or whom the method would favor. The canons first appeared on Medium (Canons of Constitutional Interpretation of Planet Gibsonia); the scholarly treatment is the manuscript Method Before Power.

Method, not power

The preamble, De Modo, Non De Potestate, states that the canons govern how legal texts are read and do not allocate authority to read them. Any court, council, chamber, administrative or arbitral body, citizen assembly, or authorized computational system is bound by the same method. The manuscript frames this as two constitutional objects: a power constitution, which allocates competence, and an interpretive constitution, which says how exercises of competence are understood. Gibsonia enacts the second before the first. The motto is a sequencing claim, not a neutrality claim.

The individual canons are mostly borrowed from Earth. What is new is their legal form. They are enacted law, not professional advice; the set is closed and changes only by amendment; they are ordered by layer and backed by a substantive conflict hierarchy; admissible sources are ranked; and an interpreter who invokes an exceptional doctrine, such as absurdity or overruling, must expose the reason.

The eight layers (version 1.1 numbering)

1. Textual Authority. Verba Suprema (1): ordinary public meaning at enactment, technical meaning for technical terms. Nulla Superfluitas (2): no word is idle.
2. Structural Coherence. Contextus Regit (3): read the instrument as a whole. Structura Vincit (4): no reading may collapse or enlarge a structural feature by implication. Consistentia Verborum (5): a term keeps one meaning, and different terms presumptively mean different things.
3. Hierarchy and Specificity. Expressum Praevalet (6): the express beats the implied. Specialis Derogat Generali (7): the specific beats the general at the same level of the legal hierarchy.
4. Rights Protection. Libertas Praesumitur (8): ambiguity about a right that survives the preceding canons resolves for the individual. Onus Restrictionis (9): a restriction needs a clear textual basis, a legitimate purpose, a rational and direct connection to it, narrow tailoring through the least restrictive means reasonably available, and proportionality. Silentium Pro Libertate (10): silence is not a grant of power.
5. Conflict Resolution. Concordia Praeferenda (11): harmonize where good faith allows. Ordo Praevalet (12): the priority rule, below. Pars Corrupta Non Inficit Totum (13): an invalid part does not sink the whole.
6. Temporal Stability. Fixatio Significationis (14): meaning is fixed at enactment. Mutatio per Emendationem (15): meaning changes only by amendment. Lex Praevia (16): no retroactivity without clear authorization, and never to punish. Stare Decisis Nisi Manifeste Erratum (17): precedent binds unless shown manifestly erroneous under the canons, with reliance addressed and the overruling itself reasoned under the canons.
7. Interpretive Discipline. Prohibitio Manipulationis (18): no pretext, and every binding interpretation discloses its canons, sources, and priority rules. Dissensus Servandus (19): reasoned dissents are preserved. Clarus Vincit Propositum (20): purpose illuminates ambiguity but never overrides clear text. Fontes Limitati (21): four ranked sources (text, structure, consistent precedent, contemporaneous public meaning); everything else illuminates only. Bona Fide Interpretatio (22): fair meaning, engagement with contrary argument, candor about uncertainty.
8. Emergency Valve. Absurditas Vitanda (23): the nearest non-absurd reading, only for results that are logically, internally, physically, or mathematically impossible, never for results that are merely unwise.

The full text lives with the original article.

The priority rule

There are two priority systems. Methodological priority comes from the layer sequence and local rules such as specific-over-general. Substantive priority comes from Ordo Praevalet: when provisions cannot be reconciled, fundamental individual rights displace structural constraints on government, which displace enumerated governmental powers, which displace administrative and procedural provisions. Within a category, the specific controls. A decision invoking the rule must say how it classified each provision and why reconciliation failed. The hierarchy is liberty-oriented, and the manuscript says so plainly: its value is that it exposes a normative commitment that other systems let in less visibly.

What version 1.1 changed

Supplement S1 normalized the instrument. The Medium text numbered two canons 5 and two canons 18 (both inserted after numbering was fixed), and it left Consistentia Verborum and Dissensus Servandus truncated. S1:

• renumbers the set 1 to 23 and completes both truncated canons, so that a preserved dissent can prompt reconsideration but cannot displace precedent without satisfying Stare Decisis Nisi Manifeste Erratum;
• adds a rational-connection prong to Onus Restrictionis, requires disclosure under Prohibitio Manipulationis and candor about uncertainty under Bona Fide Interpretatio, and splits the absurdity categories into four while demanding the narrowest correction;
• extends the preamble to arbitral bodies, citizen assemblies, and computational systems, declares the canons a closed law of interpretation, and forbids any interpreter to create, abolish, or reorder a canon through adjudication;
• requires every binding interpretation to keep a machine-readable and human-readable record of nine items: the question, controlling provisions, candidate readings, canons triggered, sources used, the priority relation applied, predicates supplied by an institution, expert, or computational system, the conclusion and remedy, and any dissent or unresolved uncertainty.

How to apply it

The manuscript's worked example is the Habitat Corridor Closure. Article 4 guarantees free movement between inhabited districts. Article 12 lets the Council restrict movement temporarily when a verified life-support failure creates an immediate danger. A statute lets the Administrator close any corridor during a declared emergency when closure materially assists emergency operations. After contamination in Habitat C, three corridors close. Forty-eight hours later engineers certify that the danger has passed, but the Administrator keeps the corridors closed for thirty more days because centralized deliveries are easier.

• Layer I. Reading the power to continue after the danger ends leaves "when," "immediate," and "temporarily" doing no work.
• Layer II. Article 12 is an exception to Article 4; reading it as a convenience power lets the exception consume the right.
• Layer III. The statute is more specific than Article 4, but specificity operates within one level of the hierarchy. A statute cannot enlarge a constitutional exception.
• Layer IV. Continued restriction needs a clear textual basis, which disappears with the danger, and a thirty-day closure is unlikely to be the least restrictive way to simplify deliveries.
• Layer V. A fundamental right and structural limits on emergency power outrank an administrative provision.
• Layer VIII. The absurdity valve is unavailable. Following the text is inconvenient, not impossible.

The closure was lawful during the verified danger and unlawful after it, unless a new emergency was independently authorized. An excerpt from the manuscript's rule sketch shows where computation stops:

r2: no_immediate_danger => not_permitted(closure_under_article_12)
r3: restriction_of_movement AND no_clear_textual_basis => invalid(restriction)
r4: restriction_of_movement AND not_least_restrictive => invalid(restriction)
r6: legitimate_interest => supports(restriction)
priority: r2 > r6; r3 > r6; r4 > r6

Once the facts behind no_immediate_danger and not_least_restrictive are found, the result follows from the priorities. Finding those facts takes evidence and institutional judgment, and the architecture records that dependency instead of hiding it. The same trace governs whoever decides, from a court to a compliance system issuing a non-binding alert.

Known limitations and critiques

The manuscript names most of these itself.

Method is a form of power. A rights-first hierarchy favors some constitutional arrangements over others. Read as a neutrality claim, the motto is false; read as a sequencing claim, it holds.

The veil is imperfect. Founders can foresee that a presumption of liberty will constrain regulators. Enacting method first reduces tailoring to known disputes; it does not remove strategy.

Canons stay open-textured. "Ordinary," "legitimate," "proportionate," and "manifestly erroneous" require judgment, and canons can conflict at the meta-level. The aim is bounded contestation, not mechanical determinacy. Whether an explicit ordering answers Llewellyn's dueling-canons critique remains an open question.

Closure can entrench error. A closed set may preserve bad design and constrain later democratic judgment. The answer is a real amendment channel, prospective and public, not interpretation in disguise.

Formalization can launder judgment. A predicate such as "least restrictive" can be presented as fact when it is a contestable output. Every non-obvious predicate needs its provenance recorded.

Too constitutional for ordinary law. Rights proportionality may be too rigid for private law; one answer is a common core with domain modules.

Untested, and not quite one text. The design has not yet been formally encoded or tested with experts. The Medium edition is also reported as twenty-four canons, and the Version Control for Law essay invokes canons (Versio Enactionis, Relatio Certa, Scriptoris Error, Manifestatio Ambiguitatis) that do not appear in the twenty-three-canon text. This page follows the S1 text.
