Maygan Sensenberger, wife of Senator Rod Zimmer, has had her case adjourned until Thursday.

Sensenberger, who is charged with causing a disturbance and uttering threats, was expected to enter a plea, but her lawyer appeared on her behalf instead, according to CBC's reporter on the scene. The case is being heard in a Saskatchewan domestic violence court.

The much more serious charge of endangering the safety of an aircraft was dropped last month.

The charges stem from an incident which occurred last month on an Air Canada flight from Ottawa to Saskatoon. Sensenberger is alleged to have threatened to slit Zimmer's throat.

However, some witnesses to the incident have said Sensenberger became upset when Zimmer began to feel ill and that she was simply trying to get her husband medical attention.

Alcohol is thought to have been a factor in the incident. Sensenberger has a previous DUI conviction stemming from an accident in her native Collingwood, Ont, in 2008.

If Sensenberger pleads guilty, as she did in the impaired driving case, it may make her life significantly more complicated.

A guilty plea would likely result in an order to seek treatment and counselling. But, according to Metro, Sensenberger would likely have to stay in Saskatoon to receive that treatment.

Sensenberger and Zimmer live in Ottawa.

Due to a court order, the couple are currently only able to communicate remotely via phone or Internet.

The case has garnered widespread attention in Canada, and around the world, largely due to the couple's age difference. Zimmer is 69 and Sensenberger is 23.

Photos of the pair's world travels and posh wedding posted to Facebook also helped catapult the story to the top of the headlines. Access to those photos has since been cut off.
