Although there has been some media coverage of organised legal appeals by groups of those affected, the matter has recently gained enhanced attention by mainstream media and the wider public as a whole, and is currently being acted upon by authorities in an attempt to accelerate and automate the clearing of the names of all those wrongly convicted, who until now were required to launch their own legal appeals in order to have their names cleared.
