To offer the most optimal method of ensuring adversary of the parties during the pre-trial stage for legislators of the Republic of Kazakhstan, legislative practice of France, Germany and the USA were studied. While studying the criminal process of these countries the French model of the adversarial nature of criminal proceedings is recognised as not acceptable due to the conduct of preliminary investigation in this country by forensic investigators.
