This study examines 14,900 disciplinary actions by the professional licensing boards for attorneys, CPAs, and physicians in four states from 2008 through 2014. It was found that both attorneys and physicians are disciplined at a rate at least seven times that of CPAs. While the majority of disciplinary actions are for misconduct directly related to the professional practice, nearly 14% of sanctions were the result of “social crimes” such as failure to pay child support or student loans, driving under the (...) influence, and general unprofessional conduct. The severity of licensure sanctions varied with the cause for discipline, but was inconsistent both within and between jurisdictions. These results raise important questions about the purpose and performance of state licensing boards and possible reasons for inequitable treatment. Additionally, the widespread and severe sanctions for conduct not related to the professional practice suggest that moral turpitude clauses may violate both equal protection and prohibitions on excessive fines.
