In June 2017, ATSA submitted an amicus brief in the Supreme Court case Karsjens v. Piper, critically analyzing Minnesota's sex offender civil commitment system. The brief argues against the blanket civil commitment of sex offenders, highlighting that such practices often fail to consider the diverse risk profiles and rehabilitative needs of individuals. ATSA emphasizes the necessity of empirically grounded approaches in assessing and managing sex offenders, challenging the constitutionality of broad and inflexible commitment systems.

The brief stresses that sexual offenders are not a homogeneous group, and their risk of recidivism varies considerably. It argues for individualized assessment and treatment that align with the offender's specific risk factors and needs. Furthermore, ATSA advocates for treatment and management strategies that are less restrictive and more aligned with recent scientific evidence, promoting community safety while respecting individual rights. This significant brief underscores the need for a nuanced approach in legal and treatment frameworks for sex offenders, rooted in current empirical research and best practices.
