Constitution of Uruguay (Constitución de la República de Uruguay), accessed 25 September 2024

Article 88

 The Chamber of Representatives is composed of ninety-nine members elected directly by the people, under a system of proportional representation which takes into account the votes cast in favor of each lema in all the country. 

Accumulation by sublemas [factions] or through identity of lists of candidates cannot be effected. 

Two Representatives, at the least, will correspond to each Department. 

The number of Representatives may be modified by the law, that shall require for its sanction, two-thirds of the vote of the total of the membership of each Chamber.
