An electoral law expert says the National Party can't entirely wash its hand of the fraud charges laid against Jami-Lee Ross.
Ross used to be a National Party MP but is now independent.
He's named as one of four people facing charges in relation to two $100,000 donations to the National Party.
The three other defendants are Yikun Zhang, Shi-jia Zheng, and Hengjia Zheng.
The charges relate to separate donations made in June 2017 and June 2018.
Otago University law expert Andrew Geddis speaks to Susie Ferguson.
