WINNIPEG - The lawyer for a Winnipeg woman convicted of hiding the remains of six infants in a rented storage locker is trying to get the case dismissed.

Greg Brodsky has filed a motion to have the case thrown out because it has taken 33 months to conclude.

A Supreme Court ruling last year said legal proceedings can be presumed to be unreasonably delayed if they take more than 18 months in provincial court or 30 months in a higher court.

Andrea Giesbrecht was arrested in October 2014 after the remains were found in a U-haul storage locker she rented.

Medical experts testified the infants were Giesbrecht's, were at or near full term and were likely to have been born alive.

She was convicted earlier this year and a judge is to decide her sentence on Friday, but Brodsky says he will be in court that morning to try to have the case thrown out.
