Electoral monitoring is a tool for citizen participation (credibility or not of elections) in the service of democracy. The following analyses show that electoral monitoring is built on the one hand through an investigation of electoral standards in terms of credibility, a description of electoral institutions in terms of effectiveness and on the other hand, an evaluation of the democratic quality of electoral standards and an assessment of the legitimacy of electoral procedures and processes. Given the current state of progress of the Cameroonian electoral process, is it possible to classify Cameroon as a democratic country? The answer to this question is mixed! Because the dynamics of building electoral monitoring reveals various challenges and limitations. Indeed, electoral monitoring, which could serve as a yardstick for assessing democracy and the rule of law, is plagued by numerous endogenous and exogenous obstacles that limit the full exercise of the right to vote by a good number of Cameroonian citizens.
