All except for Nalle.
Nalle, a graduate of Harvard College and the University of Pennsylvania Law School, acts as general counsel for Merial, a Duluth-based worldwide animal health pharmaceutical producer and marketer that produces products that help protect cats and dogs from fleas and ticks.
However, "Nalle hasn't had an active legal license since 2000, when he asked the State Bar of Pennsylvania to move him to inactive status," continues the article. "[Nalle] asked to go inactive because he moved to London in 1997 when he helped create Merial as a joint venture between Merck and sanofi-aventis."
But "inactive is supposed to mean you're not in any way actively engaged in the practice of law," said Timothy P. Terrell, an Emory Law School professor of ethics. "If they're going to call themselves general counsel, and if a corporation can get the benefit of their advice, then they ought to be licensed."
Nalle claimed he has been involved in other non-legal matters, including communications and public affairs and has had "licensee lawyers working in his department," says the article. He has also "employed outside counsel for external legal matters."
An issue here, however, according to William P. Smith III, general counsel of the State Bar of Georgia is that the "separation between business and legal advice 'becomes a little gray.'" (law.com)
