The Federal Court has struck out an appeal by P Uthayakumar, who sought to compel the court to instruct the federal government to establish a Royal Commission of Inquiry (RCI) on prison reforms.

Court of Appeal president Justice Md Raus Shariff, who led the five-member panel, stated that they agreed with preliminary objections raised by the senior federal counsel.

"We are unanimous, we are not with you," Justice Raus said in delivering the decision.
