Selected Representative Experience
05/11/2001 - Ethical and Practical Issues Arising In the Face of a Govt. Investigation
Enforcement actions against corporations and their employees are becoming more common, especially criminal enforcement actions. These actions raise several conflict and ethical issues that must be addressed by lawyers defending either the company, the employees, or both. Many of these conflict issues are inherent in any situation where the degree of liability varies across a collection of people or entities. Some of these conflicts arise or are exacerbated, only because of certain aggressive tactics the government uses in its investigations.
