The protection of witnesses is regulated by articles 247-252 of the Code of Criminal Procedure and Supreme Decree No. 003-2010-JUS. Measures adopted include the provision of a change of address, the withholding of identity and economic measures to enable a witness to change his or her residence or place of work. The Supreme Decree established an integrated programme for the protection of witnesses, experts, victims and collaborators involved in criminal proceedings. The programme is operated by the Attorney General’s Office and protection units are established in every judicial district. No agreements or arrangements have been entered into with other States for the relocation of witnesses. However, contacts exist at the technical level. Victims enjoy the same protection as witnesses, but they also have the opportunity to appear as a civil party and to be given a hearing before any decision involving the termination or suspension of criminal proceedings.
