Frequently Asked2
How does the substantial relationship test determine conflicts between former and current clients?+
The test examines whether the prior and current matters share factual or legal issues such that confidential information from the earlier representation would be material to the later one. Both prongs of the imputation rule must be satisfied before disqualification occurs. When the second prong is absent because no remaining lawyer holds material confidences, the firm may proceed even if the matters overlap.
Does the substantial relationship test apply differently in equal protection challenges involving gender classifications?+
In equal protection cases the test requires the government to show that a gender classification is substantially related to an important governmental objective. The justification must be genuine and not based on stereotypes. Courts apply the test to invalidate laws that rest on outdated assumptions about marital roles or parental authority.
Samuel Soto registered as a putative father and sought to set aside an adoption decree. He argued that the agency failed to provide proper notice of the proceeding. The court applied the substantial relationship test and held that his timely registration created the required connection triggering formal process rights.
