implementation of the principle of inevitability
of liability for offenses and compliance with pre-
trial investigation. The completeness of the
investigation and disclosure of a criminal offense
depend on how quickly the procedural actions are
carried out, which will help to protect the
legitimate interests of persons involved in
criminal proceedings; completeness means that
all circumstances to be proved in criminal
proceedings are established. In this regard
Shcherbakovskyi et al (2020, p. 123) note that
errors and violations that take place at the stage
of pre-trial investigation lead to the restriction of
human rights and freedoms;
ensuring compensation to individuals and legal
entities for damage caused by criminal offenses
(lies in the most effective implementation of
criminal procedural and administrative tools by
the inquirer to legally achieve the goals and
objectives of pre-trial investigation and creating
appropriate grounds for further compensation to
individuals and legal entities for damage caused
by criminal offenses);
identifying the causes and conditions that
contribute to the commission of criminal
offenses, and taking measures to eliminate them.
Besides, the main functions of inquiry units are:
the analysis of the practice of pre-trial
investigation of criminal offenses, organization
and results of the activities of the inquirers, and
making proposals for efficiency gains (which can
be implemented through systematic individual
evaluation of inquirers, by rating, taking into
account all objective, subjective factors);
use of means to improve the quality of the inquiry
and compliance with its deadlines;
study, generalization of positive experience of
inquiry, its introduction into the practice of
inquiry units, development of modern methods of
investigation of certain types of criminal offenses
(which is expressed in borrowing international
experience of units conducting pre-trial
investigation of criminal offenses);
organization of interaction of inquiry units with
other units of the National Police, investigators
and detectives of other law enforcement
agencies, entities engaged in forensic activities,
units engaged in operational and investigative
activities, as well as prosecutors, who supervise
compliance with the law during pre-trial
investigation in the form of procedural guidance
of pre-trial investigation (carried out directly by
the inquirer in the pre-trial investigation, by
drawing up procedural documents);
studying the practice of application of legal
norms by inquirers and development of proposals
to improve the legislation of Ukraine (which is
reflected in the creation of high quality
methodological support for inquiry units of the
National Police of Ukraine, formed using the
practice of application of legal norms, statistics);
ensuring selection, placement and education of
personnel for inquiry units, improving their skills
and professionalism (which serves as a basis for
further development of the inquiry institution in
Ukraine as a body authorized to investigate
criminal offenses and is reflected in the
development of training programs, training
courses qualifications and professional skills, as
well as trainings, seminars, workshops and the
creation of other formats and algorithms for the
training of inquirers and persons authorized for
inquiry in the National Police of Ukraine);
addressing and adjudicating on citizens’ appeals
received in relation to the inquiries.
The powers, in contrast to the tasks and
functions, are defined only for a few categories
of inquirers, namely for the Head of the Inquiry
Department of the National Police of Ukraine;
Head of the Main Directorate of the National
Police Inquiry Department (sector); Head of the
Department (sector) of Inquiry of the Territorial
Police Unit. In turn, these powers are generally
formulated almost identically, duplicating and
differentiating depending on the level of
administrative importance of the post occupied
by the relevant manager.
One of the most important elements of the
organizational and legal framework for the
functioning of any public authority is the
mechanisms of responsibility and control,
supervision of specific activities.
The most accurate in the context of the need to
define the concept of responsibility of the
inquirer as an official of the police and the
procedural person carrying out pre-trial
proceedings is the consideration of existing
scientific provisions on the interpretation of the
relevant category.
Legal liability arises precisely because the
subject of the offense is in a general relationship
of responsibility with the State, but breaks this
connection by an act of irresponsible behavior.
This statement most accurately and clearly
reflects the essence of the responsibility of the
inquirer – the violation of previously assumed
legal obligations, for which there is a necessary
and inevitable legal consequence.
In order to prosecute officials of the National
Police of Ukraine and persons authorized to
conduct pre-trial investigations of criminal
