The ways of increasing the effectiveness of prosecutorial supervision over the execution of laws by bodies carrying out pre-trial investigation are indicated. The author actualizes: the essence, the significance of the prosecutor's supervision over the legality of pre-trial investigation and its role as a separate object; the significance and role of the principle of legality as the main and leading beginning of the entire criminal process of the Republic of Kazakhstan; the definition of the boundaries of the prosecutor's supervision over the legality of pre-trial investigation.
