Law No. 165, 2017 – Electoral Law – “Amendments to the system of election of the Chamber of Deputies and the Senate of the Republic. Delegation to the Government for the determination of uninominal and multi-nominal electoral constituencies.”

First, under penalty of ineligibility, in the internal succession of lists in the multi-member constituencies of both the House and the Senate, candidates must be placed in an alternating gender order. At the same time, in the Chamber, it is stipulated that in the total number of nominations submitted by each list or coalition of lists in the uninominal constituencies at the national level, neither gender may be represented by more than 60 percent, rounded up to the nearest unit. In addition, in the total number of lists in multi-nominal constituencies submitted by each list at the national level, neither gender may be represented in the position of leading candidate to an extent exceeding 60 percent, rounded to the nearest unit. The Central National Office ensures compliance with these requirements. In the Senate, the same requirements are set at the regional level, and it is the responsibility of the Regional Election Office to ensure compliance.
