The trial of two Canadian men from a fundamentalist sect that allows men to have multiple wives opened Tuesday with not guilty pleas being entered on charges of practicing polygamy.

Winston Blackmore and James Oler each face one count of polygamy. Both men have served as bishops for the religious settlement of Bountiful, British Columbia which follows the teachings of the Fundamentalist Church of Jesus Christ and Latter-Day Saints, often referred to as the FLDS.

Oler is accused of having four wives. He pleaded not guilty. Blackmore remained mute and Justice Sheri Ann Donegan said a not guilty plea would be entered on his behalf. Blackmore is accused of marrying 24 women over 25 years.

Blackmore's lawyer, Blair Suffredine, said outside court his client chose to say nothing for religious reasons.

"He doesn't want to deny his faith. He doesn't feel guilty," Suffredine said. "The technical way around that is don't say anything and they'll enter the plea not guilty."

Special prosecutor Peter Wilson told the court his case includes marriage records seized from the church's Yearning for Zion Ranch in Texas, which were used in 2010 to sentence leader Warren Jeffs to life in a U.S. prison for sexually assaulting two young girls.
