Last month, Ms Walker told 9news.com.au she was fighting the conviction in part because the "system is built more in favour of the abuser than the victim".

In an application to Supreme Court, Ms Walker's attorney argued she should have the right to appeal based on a lack of precedent surrounding justifiable self-defence in the Icelandic penal code and inconsistencies in testimony from her ex-husband and his now-partner, who is the woman assaulted in the fight.

Ms Walker claimed her ex-husband and the woman had lied about their relationship in court and that her own injuries, nor those of an impartial American witness, were not considered in the verdict.

The application said the severity of the injury to her husband had "clouded" the court'shave been striving not only for the truth to be acknowledged, but for a system to become more aware of a life so many of us endure each day.

Ms Walker has been on a travel ban since her arrest 15 months ago and has been unable to leave Iceland, even to exhibit her art overseas.

Ms Walker said her physical suffering has been compounded by her treatment by the legal system and she has been diagnosed with post-traumatic stress disorder.
