Article 4.2 of the Law on Presidential Elections provides that, “if one of the candidates who are entitled to participate in the second round does not participate to the election for any reason, in the second round, the vacant seat is substituted according to the result of the first round. However, substitution may be made until 5 pm on the day following the announcement of the temporary results.” 5 pm is a short time; a minimum of 24 hours after the provisional (temporary) results would be preferable.
