The case of a couple facing 28 charges connected to the possession and exportation of narwhal tusks has been adjourned again.

Gregory Robert Logan, 54, and Nina Lorene Logan, 51, were scheduled to enter pleas in St. Stephen provincial court on Tuesday.

But their defence lawyer asked the court for more time.

The matter will now be heard on June 12.

The Logans, who are from Grand Prairie, Alta., and summer in Woodmans Point, near Grand Bay-Westfield, were not present in court.

The narwhal is a medium-sized whale that lives year-round in the Arctic. Male narwhals have a single straight tusk that can measure up to 2.5 metres long.

Twenty-seven of the charges, laid by an Environment Canada wildlife officer, allege that between September 2003 and August 2009, the Logans unlawfully transported narwhal tusks into St. Stephen.

The remaining charge alleges the pair knowingly possessed the animal parts with the purpose of exporting them from Canada.

This is the second time the Logans' case has been adjourned. The couple was previously scheduled to enter pleas on April 17, but the matter was set over to allow their defence lawyer more time to review the Crown’s case.
