Measure the Erdős-equivalent distance between an expert witness and the parties they are supposed to be independent from. Direct connections in specialist networks are statistically improbable — unless they are not accidental.
Based on published research · SSRN #6905898 · CEJ Biblioteca Armando Leandro → Expertise Check (SDD tool)What this measures: The Network Proximity Score (NPS) is the inverse of Semantic Delegation Distance. Where SDD measures the gap between practitioner and work, NPS measures the closeness between expert and party. An Erdős-1 connection (direct co-authorship, doctoral supervision, or prior employment) in a specialist field is statistically rare by the mathematics of scale-free networks. Two simultaneous direct connections across independent dimensions (a bipartite signal) are vanishingly unlikely to occur by chance.
Court case, arbitration, or proceedings description — who are the parties and what role is the expert playing?
CV, academic profile, publication list, doctoral history, and institutional affiliations of the expert witness.
Profile of the party the expert should be independent from — include institutional affiliations, key personnel, and professional history.

Network Proximity Check is one of three diagnostic instruments in The Procedural Gap Project — each grounded in published academic research on structural failures in legal procedure.
