Scott Hutchison, lawyer for Laura Miller, said Thursday that the defence does not intend to call any evidence but indicated that it would need about three hours for legal arguments.
Miller and David Livingston, two former senior staffers in the premier’s office, face charges of attempted mischief to data and unauthorized use of a computer.
A charge of breach of trust was dropped by the Crown.
Prosecutors allege that the pair went to extraordinary and illegal lengths to wipe out records on government computers that they were required to keep.
The defence has asserted the pair, who have pleaded not guilty, had the right to delete personal and political emails, and that prosecutors have presented no evidence that any other documents were destroyed.
