(1) Everyone shall have the right to have any charge against him or her, or his or her rights and obligations in any litigation, adjudicated within a reasonable time in a fair and public trial by an independent and impartial court established by an Act.
(2) No one shall be considered guilty until his or her criminal liability has been established by the final decision of a court.
(3) Persons subject to criminal proceedings shall have the right to defence at all stages of the proceedings. Defence counsels shall not be held liable for their opinion expressed while providing legal defence.
(4) No one shall be held guilty of or be punished for an act which at the time when it was committed did not constitute a criminal offence under Hungarian law or, within the scope specified by an international treaty or a legal act of the European Union, under the law of another State.
(5) Paragraph (4) shall not prejudice the prosecution or conviction of any person for any act which, at the time when it was committed, was a criminal offence according to the generally recognised rules of international law.
(6) With the exception of extraordinary cases of legal remedy laid down in an Act, no one shall be prosecuted or convicted for a criminal offence for which he or she has already been finally acquitted or convicted in Hungary or, within the scope specified by an international treaty or a legal act of the European Union, in another State, as provided for by an Act.
(7) Everyone shall have the right to seek legal remedy against any court, authority or other administrative decision which violates his or her rights or legitimate interests.
