A defense attorney said Wednesday he sees a federal court’s opinion upholding e-mail privacy as groundbreaking and possibly helpful to his client, the founder of a company that sold male enhancement pills.

Lawyer Martin Weinberg said e-mail evidence should have been excluded from the government’s case against Steven Warshak, who was convicted of fraud and other crimes related to his Ohio company. The company, Berkeley Premium Nutraceuticals Inc., sold products including Enzyte pills — known for their commercials featuring Smiling Bob, whose life improves after using them — and other herbal supplements promoted as treating a variety of health and personal conditions.
