In legislative districts where only one candidate qualified for the election, the latter must receive the approval of the majority of the entire votes cast in an approval system of voting for the same to be declared duly elected, otherwise a failure of election must be declared. In legislative districts where two candidates qualified for the election, the candidate who received the highest number of votes must be declared duly elected, and in case of tie, a failure of election must be declared. In legislative districts where three or more candidates qualified for the election, the candidate who received the majority of the entire votes cast in a preferential or alternative system of voting must be declared duly elected, otherwise a failure of election must be declared. In case of a failure of election, an extraordinary election must be called to fill such vacancy in the manner prescribed by law.
The seats in the National Assembly that are reserved to Party-list Representatives shall be allocated to political parties proportionally to the number of votes each party received in the party-list portion of the ballot. The quota of votes required to win a seat shall be determined by the formula: (V / (S + 1)) + 1, where V = total number of valid party-list votes, and S = total number of seats to be filled. To allocate seats, the number of valid party-list votes for each party shall be divided by the quota, resulting in an integer and a fractional remainder; each party shall first be allocated a number of seats equal to the integer; parties shall then be ranked on the basis of the fractional remainders, and the parties with the largest remainders shall each be allocated an additional seat until all the seats have been allocated.
Only a political party that receives at least two per centum of the total valid party votes cast shall be entitled to the share in the distribution of party-list seats. However, a party that receives fewer votes shall still be entitled to keep any legislative district seats that it wins.

In case any vacancy arises among the District Representatives, an extraordinary election may be called to fill such vacancy in the manner prescribed by law, but the Representative thus elected shall serve only for the unexpired term.
In case of vacancy in seats reserved for Party-list Representatives, the party concerned shall automatically fill the vacancy with the next Representative on their list submitted under Article 165, who shall serve for the unexpired term.
