Connie Oakes was convicted by a jury two years ago in the death of Casey Armstrong.
The man was found stabbed through the neck in the bathtub of his trailer in Medicine Hat, Alta. in 2011.
Oakes was convicted of second-degree murder and her co-accused, Wendy Scott, pleaded guilty to the same charge.
According to court documents, Scott has since retracted her confession as well as her testimony at trial.
Oakes is appealing her conviction and a Calgary judge has promised a decision on her bail application by Friday.
Oakes, who was given a life sentence with no chance of parole for 14 years, calls her conviction an "unreasonable verdict." Her appeal in the case is to be heard Nov. 12.
Scott is serving a life sentence with no parole for 10 years.
