The article looks at changes regarding the right to counsel at the stage of explanatory proceedings in petty offence cases. The changes were implemented by the 15 May 2015 amendment. The existing status of the right of defence at the pretrial stage of the petty offence procedure has also been affected by the previous amendments of the procedure, namely from 27 September 2013 and 12 May 2015. The article discusses the state of law before and after the amendments. Rewritten Art. 4 of the Code of Petty Offence Procedure guarantees the right of defence to a person subject to the request to impose a penalty on clear grounds, which restores the relative equality of the parties at the stage of explanatory proceedings. Affording the person referred to in Art. 54 § 6 of the Code of Petty Offence Procedure the assistance of a professional counsel does not only safeguard their constitutional rights but also validates the proper operation of the investigating authorities.
