Voting centers were relocated by the pro-government National Electoral Council (CNE) citing security reasons, despite the fact that the 2017 Venezuelan protests ended after the Constituent Assembly election.

[7] On 2 December 2017, Vicente Bello, the National Electoral Council representative of the Un Nuevo Tiempo (UNT) opposition political party denounced irregularities during the audit of the voting machines and delivered a document to UNT leader Luis Emilio Rondón [es] that stated that "the established protocol related to the selection of samples by status in the line of production and their subsequent verification", "the schedules set for the start of daily activity" and that the respective shifts were modified without prior notice, warning that the CNE did not establish that the samples of the selected machines were subsequently verified for proper functioning.

[9] Furthermore, the Observatory denounced the elimination of the inscription of new voters for the Electoral Registry, its precarious revision and the limitation for national and international observation, whose accreditations are granted discretionally by the CNE.

Other factors criticized by the organization were the arbitrary conformation of the municipal regional boards, whose chosen voters were the same ones chosen in a public and automated raffle on 31 March 2016, and the fact that despite that the CNE promised to review the modification and relocation of the polling stations during the previous regional elections, two days before the election several centers remained in different locations without determining the total number of stations that remained in that condition.

[9] In the Simón Planas municipality in the Lara state, the chavista and Constituent Assembly member Ángel Prado at first was denied the inscription of the independent candidacy despite getting signatures of 32% of the voters in the municipality, receiving later support from the Communist Party of Venezuela, the MEP, the Tupamaro, the ORA and the Patria para Todos parties, of which the latter changed its support for the PSUV candidate to Ángel Pardo, change endorsed by Resolution Nro.

Other irregularities denounced by the specialists were the disproportionate use of political propaganda near polling stations and the use of the Carnet de la Patria [es] as a coercion method of the voter.

[21][22] In an afternoon press conference, Jorge Rodríguez assured that those who voted in the municipal elections and registered their participation in the tricolor points with the Carnet de la Patria "would receive a gift".

[23] The coordinator of the electoral center of the Andrés Bello school in La Candelaria parish in Caracas denounced that the National Electoral Council did not hagive the credentials to the board members and witnesses who supported the candidate for mayor of the Libertador municipality Maribel Castillo, so they could not seal, sign or access the polling station, while they were delivered the night before to the representatives of the Patria Para Todos party and the United Socialist Party of Venezuela.

[20] In the Udón Pérez voting center, in Maracaibo, twenty motorcyclists with passengers verbally threatened voters and journalists, including Zulia state candidate Manuel Rosales, throwing explosives before retiring.
