After Rana appeared before a US court for a pre-trial conference, his lawyer told the reporters that Rana will not plead guilty and that the case will go on as the 26/11 accused has a 'strong case'.
This comes weeks after Pakistani American terrorist Headley pleaded guilty before a court to strike a plea agreement with the US prosecutors.
The Pakistan-born Canadian terror suspect's lawyer Patrik Blegen said that it was not a surprise that Headley had pleaded guilty.
Prosecutors and the defence attorney have set further dates for scheduling the handling of classified information in the case.
Next hearing has been scheduled for May 11.
Both Headley and Rana have been charged with conspiring and plotting the 26/11 Mumbai terror attacks. Ever since his Oct 2009 arrest Rana has maintained that he is not guilty and that he was duped by Headley.
