The main aim of the paper is to discuss legal frames of disciplinary liability of students under the Higher Education and Science Act of 20 July 2018. Assuming that disciplinary liability constitutes a type of sensu largo penal liability, the stress is put on the shortcomings of current regulations in terms of the limits of this kind of legal responsibility. Since the definition of ‘disciplinary misconduct’ is partial, the author concentrates on whether the provision requiring disciplinary bodies to apply – mutatis mutandis – the provisions of the Code of Criminal Procedure in matters not governed by the Higher Education and Science Act, enables (or even obliges respective authorities) to apply provisions contained in chapters I-III of Criminal Code.
