Extrinsic fraud¶
Fraud collateral to the merits of a case that prevents a party from fairly presenting a claim or defense and can support exceptional relief from a judgment under applicable law.
Core Idea¶
Examples can include keeping a party away, concealing the proceeding, corrupting the adjudicative process or preventing evidence from being presented; jurisdictions differ sharply in terminology, deadlines and whether modern rules retain the intrinsic–extrinsic distinction. Deception or obstruction operates outside the issue adjudicated, deprives a party of notice or a meaningful opportunity to be heard, and thereby undermines the final judgment's procedural legitimacy. The abstraction is therefore identified by a declared carrier, a transformation or constraint over that carrier, and an invariant that tells an analyst whether the named structure is genuinely present.
Scope of Application¶
Extrinsic fraud belongs to civil procedure and equity and is useful where the analyst can specify the typed civil procedure and equity carrier, defining objects and relations, parameters, conventions, evidence, boundary cases, and comparison targets, then evaluate the jurisdiction and procedural rule, judgment and proceeding, actor and conduct, timing, notice and opportunity to participate, causal prevention of presentation, intrinsic comparison, diligence, materiality, limitations, available motion or independent action, proof standard and remedy are explicit.
Clarity¶
The abstraction clarifies a crowded vocabulary by making the jurisdiction and procedural rule, judgment and proceeding, actor and conduct, timing, notice and opportunity to participate, causal prevention of presentation, intrinsic comparison, diligence, materiality, limitations, available motion or independent action, proof standard and remedy are explicit the center of the account. A claim should name the carrier, the governing operation or relation, the applicable assumptions, and the recognition test.
Manages Complexity¶
Without the abstraction, an analyst must reason directly over many local details: the carrier roles, admissibility assumptions, competing conventions, derived invariants, boundary cases, and proof or validation obligations specific to Extrinsic fraud. Extrinsic fraud compresses them into the roles in the structural signature. That compression permits comparison across instances without erasing the variables that determine validity. It also exposes which details may be varied safely and which are constitutive.
Abstract Reasoning¶
- Identify the carrier. State what the elements, states, objects, or observations are: the typed civil procedure and equity carrier, defining objects and relations, parameters, conventions, evidence, boundary cases, and comparison targets. Reject examples whose alleged carrier belongs to a different problem. 2.
Knowledge Transfer¶
Knowledge transfers strongly among subfields of civil procedure and equity because they reuse the typed civil procedure and equity carrier, defining objects and relations, parameters, conventions, evidence, boundary cases, and comparison targets, Deception or obstruction operates outside the issue adjudicated, deprives a party of notice or a meaningful opportunity to be heard, and thereby undermines the final judgment's procedural legitimacy., and type the carrier, state every parameter and convention in the definition, test that the jurisdiction and procedural rule, judgment and proceeding, actor and conduct, timing, notice and opportunity to participate, causal prevention of presentation, intrinsic comparison, diligence, materiality, limitations, available motion or independent action, proof standard and remedy are explicit, compare the nearest accepted identity, and report counterexamples, uncertainty, and limiting cases.

Neighborhood in Abstraction Space¶
Extrinsic fraud sits in a crowded region of the domain-specific corpus (12th percentile for distinctiveness): several abstractions share nearly its structure, so a description that fits it tends to fit its neighbors too.
