The author attempts to resolve the issue of the admissibility of the extension of parliamentary immunity to include disciplinary (professional) responsibility of the Deputy for actions taken in connection with the exercise of the mandate. He claims that material immunity (non‑liability) enshrined in the Constitution and developed by the Act on the Exercise of the Mandate of a Deputy or Senator, also applies to the professional activity of the Deputy, provided that such activities fall within the “scope of the mandate”, as referred to in Article 105 of the Constitution. In the conclusion, he stresses that the Deputy being at the same time an advocate accounts to the Sejm for the activities falling within the scope of the mandate.
