As stated in the Convention for the Protection of Human Rights and 
Fundamental Freedoms (thereinafter – the Convention) (Wikipedia, 2021) 
and in The Universal Declaration of Human Rights (thereinafter – the 
Declaration) (United Nations, 2021), all people have equal rights, that is 
to say, the law equally protects fundamental human rights and freedoms 
of people, regardless of their personal and social characteristics. In light 
of this, it ought to be noted that both victims of crime and the persons, 
suspected of having committed a crime, have equal rights. Following this 
line of reasoning, the main task of the entire system of criminal proceedings 
is, should the need arise, to provide each person, subjected to the criminal 
proceeding, with a real opportunity to protect his/her rights and freedoms, 
at any procedural stage (Jackson and Summers, 2018). 
But in reality, we often face with the fact that the rights and freedoms 
of the oenders (especially those,  who  have  already  committed  a  crime) 
may be secured somewhat worse than the rights of other participants 
of criminal proceedings, such as victims, witnesses, etc., because the 
oender is credited with negative characteristics, associated with his anti-
social and criminal behaviour (Landina, 2017). For this reason, national 
legislation enshrines not only the rights of everyone without exception, 
but also guarantees to ensure the rights of certain categories of persons, 
in particular the ones, who have been detained on suspicion of having 
committed a crime. In addition, it is necessary that authorised persons 
should be appointed at the legislative level in order to perform the function 
of supervising the observance of human rights during detention as a stage 
of pre-trial investigation.
 The paper puts emphasis on the fact that some rights may be violated 
during the detention of a person, namely the right to counsel (the right to 
defence in pre-trial proceedings) (Soo, 2016), the right to privacy during 
searches and taking of evidence in the pre-trial stage (Đurđević, 2016), the 
right to information (if, at the time of arrest, the person is not informed of 
his/her rights and the reasons for his/her arrest), the right to silence , etc 
(Nastiuk et al., 2020; Allegrezza and Covolo, 2013).
At the same time, the detention of a person, suspected of committing a 
crime, requires certain coercive measures, which provide for administration 
of restrictions on human rights and freedoms on legal grounds. Current 
trends in the development of national legislation, including criminal 
procedure legislation, tend to implement basic international legal principles 
ensuring the protection of human rights and freedoms (Billing, 2016). 
Therefore, considerable attention is currently paid to judicial control over 
the observance of human rights in pre-trial proceedings, including during 
the detention of a person.
In order to exercise control over the provision of fundamental rights 
and freedoms of a person during detention, procedural legislation of
