Article 42 is amended to read:

"Representatives shall have substitutes to perform their duty if the mandate of the representative is stayed or terminates before the expiration of the term for which he was elected.

A representative elected from the party slate of candidates shall be substituted by an unelected candidate from the same slate from which the representative whose mandate terminated or is stayed was elected. The provisions of this Act on preferential voting shall apply accordingly to the appointment of the substitute, and if there is no candidate appointed in such manner on the slate who would substitute the representative, the substitute shall be appointed by the political party that nominated the slate of candidates.

The representative who is elected on the slate of candidates of two or more political parties shall be substituted by an unelected candidate from such slate and from the same party to which the representative whose mandate terminated or is stayed belonged at the moment of the election. The provisions of this Act on preferential voting shall apply accordingly to the appointment of the substitute, and if there is no candidate appointed in such manner on the slate who would substitute the representative, the substitute shall be appointed by the political party to which the representative whose mandate terminated or is stayed belonged at the moment of the election.

A representative elected from an independent slate shall be substituted by an unelected candidate from the same slate from which the representative whose mandate terminated or is stayed was elected. The provisions of this Act on preferential voting shall apply accordingly to the appointment of the substitute, and if there is no candidate appointed in such manner on the slate who would substitute the representative, the representative shall be substituted by an unelected candidate who comes next in line on the slate.

A representative elected from the slate of candidates of a party which is deleted from the register of political parties after the elections shall be substituted by an unelected candidate from the same slate from which the representative whose mandate terminated or is stayed was elected. The provisions of this Act on preferential voting shall apply accordingly to the appointment of the substitute, and if there is no candidate appointed in such manner on the slate who would substitute the representative, the representative shall be substituted by an unelected candidate who comes next in line on the slate.

A representative elected in the electoral district for the election of a representative of the national minorities shall be substituted by a substitute elected in the same electoral district."
