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.

While the lawyers don’t go so far as to ask the presiding judge to dismiss the case, the clear suggestion is that Wadler’s case will be impossible to try without running afoul of legal ethics rules.
