The Utah Legal Clinic confirmed that Barnard passed away "peacefully in his sleep" from natural causes over the weekend, but did not specify the exact cause of his death.
A news release from the Utah Legal Clinic said, "Barnard was a skilled attorney, spending his career advocating for those who lacked a choice or the power to do so on their own."
During his career, Barnard represented several individuals and groups in Utah in a number of civil rights cases.
Most recently, Barnard represented the American Atheists in the Utah Highway Patrol roadside cross case. He also argued on behalf of panhandlers over a controversial proposed Salt Lake City ordinance.
A statement from the ULC said:
"We live in a more just world for his having been with us. He and his work will be deeply missed by those who worked with him and those who, without him, would likely have had nowhere to turn to protect their rights."
Karen McCreary with the ACLU says that Barnard was a champion of the people who did not have a voice. She says he fought for everyone's rights. "The rights of free speech, the first amendment, the rights of protestors, jail rights, prison population, mental health facilities, separation of church and state, the rights of women."
Attorney General Mark Shurtleff says even though they were on opposite sides of legal matters for 20 years. Barnard was a "premier defender of civil liberties."
