National health care law firm WhatleyKallas is once again teaming up with Consumer Watchdog to bring lawsuits over mandatory mail-order drug programs that allegedly discriminate against HIV/AIDS patients.

Earlier this month, Edith Kallas and Alan Mansfield of WhatleyKallas and the nonprofit consumer advocacy group sued CVS Health in the U.S. District Court for the Northern District of California on behalf of four anonymous plaintiffs. The suit, which seeks class action certification, claims that the pharmacy giant’s insurance plan violates plaintiffs’ privacy by forcing them to buy their HIV/AIDS medication at retail CVS stores or have them mailed to their home. A nearly identical suit was filed the same day in California’s Central District trial court.
