SAN FRANCISCO — In a whistleblower retaliation lawsuit brought by Bio-Rad Laboratories Inc. former general counsel Sanford Wadler, lawyers for the company are seeking to bar any testimony from the former in-house lawyer based on privileged information that he learned during the course of his work.

In court papers filed late Friday, Bio-Rad’s lawyers at Quinn Emanuel Urquhart & Sullivan and Latham & Watkins contend that California’s professional conduct rules only allow lawyers to divulge privileged information when an individual’s life or safety are at stake. The company’s lawyers also claim that defending against the lawsuit would force Bio-Rad to air privileged, confidential company information in open court.
