Constitutional arguments in a landmark polygamy case have been adjourned till December after lawyers haggled over delays in filing court documents.

Winston Blackmore, who was found guilty of polygamy earlier this year, filed noticed that he would be raising a charter challenge following the conclusion of the Crown鈥檚 case in April.

Blackmore, the polygamous leader of a fundamentalist Mormon community near Creston, was found guilty in July, along with co-accused James Marion Oler, who was also charged with polygamy.

Winston Blackmore is back in court today to launch charter arguments after being found guilty of polygamy earlier this year.

However, since the notice, there has been a few different versions of affidavits circulated informally to crown attorneys by Blackmore鈥檚 lawyer, Blair Suffredine, along with missed filing deadlines to the court registry.

Peter Wilson, a special prosecutor appointed by the provincial government to litigate the case, expressed his frustration with missed deadlines after opening the court session by asking Justice Sheri Donegan to adjourn the hearing.

鈥淚鈥檓 in a position where, under normal circumstances, I would object but understand Mr. Blackmore is entitled to his day in court,鈥� said Wilson.

Justice Donegan agreed.

鈥淭his is an important case and fairness is integral to the entire process,鈥� she said.

After indicating he would not be bringing forward a constitutional challenge before the trial process in April, Suffredine reversed course and signalled his intent to file a notice of application at the conclusion of the Crown鈥檚 case.

From there, there have been ongoing complications in missed deadlines for affidavits as well as an agreed statement of facts.

Justice Donegan adjourned the hearing over until the week of Dec. 11, where lawyers will return to Cranbrook Supreme Court.
