Magistrates union ANM said Thursday it would inform people of the "dangers" attached to the government's judiciary reform which is heading towards a popular referendum and which the union says will put prosecutors under the sway of the executive branch.

"We acknowledge the third parliamentary vote on the constitutional reform and renew our commitment, ahead of the referendum, to inform all Italians about the dangers of the (Justice Minister Carlo) Nordio bill," the ANM's central executive committee said in a statement.

"And we will do so, starting with the national assembly on October 25 in Rome.

"This reform takes away citizens' rights; it does not harm individual magistrates, but it jeopardizes the balance of power defined by our very Constitution." Premier Giorgia Meloni expressed satisfaction earlier on Thursday after her government's constitutional reform of the judiciary, including the separation of the career paths of prosecutors and judges so they can no longer switch between the two roles, won final approval from the Lower House on Thursday to complete its third reading in parliament.

The reform is then set to be put to a referendum because it has failed to get the two-thirds support needed in both houses of parliament to obviate the need for one in the case of a change to the Constitution.
