Veteran human rights lawyer George Bizos argues in a submission to Parliament that the Protection of State Information Bill is unconstitutional on several counts.
He says the current draft runs contrary to - and indeed threatens many of the fundamental values and principles enshrined in the Constitution.
Bizos, from the Legal Resources Centre's constitutional litigation unit, prepared the submission on behalf of human rights organisation Passop.
It is one of 293 written presentations sent to the National Council of Provinces' ad hoc committee processing the bill after it was passed by the National Assembly last year amid a public outcry.
The ad hoc committee will meet tomorrow to schedule further hearings on the bill.
