Crown prosecutor Harry Mallalieu, appearing for the Department of Corrections, acknowledged Wilson had the right to elect a trial by jury but the question was whether he had changed his mind "on a whim" two days before the fixture.
"The point is whether or not Mr Wilson is abusing that right. It's my submission that Mr Wilson is abusing the process."
Judge Field said a defendant's instructions to their counsel regarding trial election could change before trial and, in Mr Wilson's case, they clearly had.
One of the charges had to be amended due to an incorrect date, which was initially opposed by Mr McKenzie as it could be prejudicial. He later told the court his objection was based on "lateness" on the part of the prosecution.
Wilson sat in the dock throughout proceedings but stood when the amended charge was put to him, and confirmed to Judge Field he wanted a trial by jury on both charges.
The case will come up for a post-committal conference on January 9.
