(1) The voter can cast one preferential vote each for a person campaigning on the provincial party list and the regional party list of the party voted for.
(2) For a person campaigning on the provincial party list the voter can cast a preferential vote by entering the name of this campaigner in the free space reserved for this purpose on the official ballot. The entry is valid if it clearly shows which person campaigning of the party voted for the voter intended to name. This shall be particularly the case if the entry contains at least the family name of the person campaigning or, in case of two campaigners of the same name on the provincial party list, an appropriate feature of distinction (for instance, indication of the ordering number on the provincial party list, first name, year of birth, occupation, or address).
(3) For a regional campaigner the voter can cast a preferential vote by making a cross or other sign with ink, coloured pencil, pencil, or the like in the circle printed on the left of the name of the regional campaigner on the official ballot so as to make it unequivocally clear that he intends to cast a preferential vote for the regional campaigner listed in the same line.
(4) The preferential vote for a regional campaigner shall also be valid if the intention of the voter is unequivocally clear otherwise, for instance by ticking, underlining, other appropriate marking of the regional campaigner, or by deleting the other regional campaigners.
(5) The name of a person campaigning shall be deemed as not entered by the voter if several campaigners were indicated or the campaigner on a party list other than the party voted for was indicated.
