Attorneys for a group of terminally ill patients have sued the state attorney general and several district attorneys in an effort to prevent the prosecution of physicians who provide assistance in dying to terminally ill, mentally competent patients.

“This case is about letting the patient, the individual, choose how they will cross the threshold to death when faced with the final ravages of terminal illness,” said Los Angeles-based Disability Rights Legal Center Executive Director Kathryn Tucker, who is representing the plaintiffs, at a news conference at Debevoise & Plimpton on Wednesday.
