A group of prominent female criminal lawyers have sent a letter to the Green Party, criticising its sexual violence bill that is currently before parliament.

The women have called the proposed law deeply troubling, warning more people will get wrongly convicted if it passes. 

The bill seeks to reduce the trauma that sexual violence complainants experience when they go through the court process. For example, it proposes limitations on cross-examining of the complainant.

Criminal lawyer Marie Dyhrberg told Andrew Dickens that she does not agree with the idea of the bill. 

She says that there have been changes over the years to address these issues, so the law is not necessary. 

"When you set about to make law changes, then there has to be in response to something in say our legal system that is deeply flawed."

Dyhrberg says that the flaw in this law is the myth that the trial process is unfair and gruelling for those in sexual assault cases.

What is being proposed would not lead to a fair trial, she say.

"The system does not require change at the moment."
