Defense lawyers in the Yaz mass tort litigation in Philadelphia Common Pleas Court want to ask about the comprehensive history of contraceptive use by plaintiffs alleging that the birth control pills Yaz, Yasmin and Ocella caused them injury. Plaintiffs lawyers are in opposition out of the concern that some plaintiffs will be dissuaded from continuing their lawsuits because of questions that would delve into their sexual history.

A hearing was held Friday on whether the defendants could ask plaintiffs on a litigation questionnaire about any contraceptive methods they have used to prevent pregnancy beyond hormonal birth control methods. The Yaz/Yasmin/Ocella mass tort cases will likely become one of the high-volume programs in Philadelphia’s Complex Litigation Center.
