Conflict Severity Scoring

Assigns base severity scores based on the deontic operators involved in the collision. A direct obligation-prohibition conflict (e.g., 'You must report' vs. 'You must not disclose') receives a higher base weight than a permissive-permissive overlap. The function references a Normative Collision Matrix to map modality pairs to predefined intensity values, ensuring that violations of mandatory duties are prioritized over mere permission ambiguities.

Multiplies the base score by a coefficient derived from the Normative Hierarchy Graph. A conflict involving a constitutional provision overrides a statutory regulation, which in turn overrides an administrative rule. The function implements Lex Superior Derogat Inferiori logic by assigning exponential weight multipliers to higher echelons:

• Constitutional/Supreme: 10x multiplier
• Statutory/Legislative: 5x multiplier
• Regulatory/Administrative: 2x multiplier
• Contractual/Private: 1x baseline

Applies a time-sensitive coefficient based on the Lex Posterior Derogat Priori principle. A conflict between a newly enacted statute and a centuries-old doctrine is scored higher to force immediate resolution of the modern contradiction. The function uses a recency decay curve where the effective date of the conflicting norms is compared, and the severity is amplified proportionally to the temporal proximity of the latest norm's enactment.

Evaluates the semantic overlap between conflicting rules to determine if one is a specific exception to the other. If a Lex Specialis relationship is detected (e.g., a general tax rule vs. a specific tax exemption for veterans), the severity score is de-escalated because the resolution pathway is deterministic. The function penalizes conflicts where the rules have high semantic overlap but no clear specificity hierarchy, indicating a genuine legislative drafting error rather than a structured exception.

Calculates the transitive closure of the conflict to measure its ripple effect. A contradiction in a foundational definition (e.g., 'employee') that invalidates hundreds of dependent obligations receives a catastrophic severity score. The function traverses the Normative Entailment Graph to count the number of downstream conclusions that become logically invalid if the source conflict remains unresolved, using a dependency fan-out multiplier.

Weights the conflict by the spatial and personal jurisdiction of the colliding norms. A conflict between two federal statutes affecting all citizens receives a higher score than a conflict between two municipal ordinances. The function integrates Conflict-of-Laws Engine parameters to assess the geographic reach and population affected, ensuring that global or national contradictions are surfaced before localized administrative inconsistencies.

The algorithmic process of identifying contradictory obligations, permissions, or prohibitions within a normative corpus. This is the prerequisite step to scoring, scanning for direct collisions such as a mandatory rule (Obligatory A) and a prohibitive rule (Forbidden A) applying to the same entity. Detection must parse deontic modalities before a Conflict Severity Score can be assigned.

The task of categorizing a detected rule collision into specific types to determine the appropriate resolution pathway. Common types include:

• Obligation-Obligation Conflict: Two mandatory but mutually exclusive actions.
• Obligation-Prohibition Conflict: A direct collision between a duty and a ban.
• Permissive-Prohibitive Conflict: A right versus a restriction. This classification directly informs the severity weight assigned to the conflict.

A directed acyclic graph representing the precedence relationships between legal rules based on authority (Lex Superior), specificity (Lex Specialis), and temporality (Lex Posterior). This graph is a critical input to a Conflict Severity Scoring function, as a conflict between two high-level constitutional norms receives a higher priority weight than a collision between two low-level administrative regulations.

A computational method for resolving normative conflicts by identifying the largest subset of non-contradictory rules from an inconsistent rule base. Conflict Severity Scoring often acts as a heuristic to guide MCS generation, ensuring that rules with lower severity scores are sacrificed first to preserve the most critical, high-weight norms in the final consistent subset.

A quantitative score measuring the degree of internal consistency within a legal rule system. While Conflict Severity Scoring assigns weights to individual contradictions, the Normative Coherence Metric aggregates these scores to provide a holistic health index for the entire rule base. It is often used as a loss function or evaluation criterion for AI models performing legal reasoning.

A mode of logical inference where a conclusion can be retracted in the face of new, contradictory evidence or superior rules. Conflict Severity Scoring operationalizes defeasibility by providing a numerical justification for why one rule defeats another. A high-severity conflict triggers a defeasible override, while a low-severity conflict might simply result in an exception being carved out.
