Ms. Taylor, the British Columbia woman who was the lead plaintiff in a lawsuit that challenged laws against physician-assisted deaths, died unexpectedly Thursday of an infection resulting from a perforated colon. Ms. Taylor died peacefully and painlessly, as she had hoped, Ms. Pastine said. She was 64. In June, the B.C. Supreme Court ruled that physician-assisted deaths are protected by the Charter of Rights and Freedoms, and granted Ms. Taylor a personal exemption that would have allowed her the right to seek a physician-assisted death. The federal government appealed that decision, as well as the exemption that applied to Ms. Taylor. The B.C. Court of Appeal in August upheld that exemption. The lawsuit is now headed for the B.C. Court of Appeal and a hearing is scheduled for March, 2013. Four plaintiffs – three individuals and the BCCLA – remain part of the proceedings.
