Dr Haneef's lawyer Peter Russo has obtained emails that reveal discussions between the AFP and the Immigration Department about detaining Dr Haneef under the Migration Act if he was granted bail on a terrorism charge.
A spokeswoman for Mr Andrews has rejected suggestions he was involved in a conspiracy.
Senator Nettle says if he will not resign, the Prime Minister needs to sack him.
"The evidence points to him conspiring to subvert the court's decision to release Dr Haneef," she said.
"We can not have a minister in this Government that operates in that way to try to undermine the processes that are going on in our courts.""
