(1) If, notwithstanding its proper convocation, an electoral authority fails on the day of election to meet the required quorum or falls below the quorum during its sitting in office, and the urgency of the official act does not permit any delay, the polling officer shall carry out the official act alone. In this case he shall, if possible, consult persons of confidence in proportion of the party strength.
(2) The same applies to all official acts of an electoral authority unable to meet, because no party submitted proposals for the appointment of assessors (substitute assessors) according to § 14.
(3) Save in the cases of al. 1 and 2 and of §§ 15 al. 2, 42 al. 1 and 113 the polling officer can carry out undeferable official acts, for which he has been expressly authorised by the electoral authority.
