Article 2 of the 1991 Political Constitution of Colombia establishes as one of the essential purposes of the State, that of facilitating the participation of citizens in the decisions that affect them in the economic, political, administrative and cultural life of the Nation. 

It is not impressive at all that one day we wake up with the news that some rich and important person has stolen large sums of money and that they have come out clean from the applied justice. 

The most well-known participation mechanism is the popular vote, and in each presidential election we are convinced that the candidates are suitable to choose, when they only cover illicit acts with smiles and good rhetoric. 
Most of the time the candidates with the most budget are in charge of deceiving citizens and buying their vote. Afterwards, the results are altered and we continue in the same government without seeing changes. 

It is not necessary to go to the other mechanisms because this is already a clear example of the violation of the rights of free expression and choice, but another example may be the revocation of the mandate, which in my opinion should be applied to ALL officials elected by popular vote, but even so we cannot demand that a congressman or attorney and not even that the president retire from office.  (Law 1757 of 2015)

This is not directly violating the law because that mechanism is defined in those conditions!
 

I really don't have much to add, I hope it's pretty clear, thanks for reading. 

In the Political Constitution of Colombia of 1991 in article 258 it’s written that voting is a right and a duty; but since this participation mechanism was implemented there is no strict control to avoid fraud.

The main victims of voting fraud are poor people and people from distant towns, because politicians who are campaigning travel these places to give economic aid or threats to families in exchange for their vote, and take advantage of the situation of poverty. Their right to vote and to choose their representative with total freedom is violated. This situation leads to great long term problems due to the election of politicians, corruption and terrible administration in the country.

I would also believe that another reason for this is that there is not really a transparent entity that carries out the due and proper control when the application of any of the mechanisms is being carried out, therefore it is much easier for corruption to occur in these events.

Thanks for the attention.

The mechanism of participation that I believe has been violated to the Colombian people is the popular vote because to exercise this type of democracy it is necessary that the elections are clean, as the candidates must be, something that is currently not completely certain because democracy and the way in which this type of voting is handled in Colombia has lost credibility; they have been "uncovered" several election frauds and in my personal experience in the department where I live I have heard from some jurors who change the vote count for financial reward, aspirants to important positions on several occasions carry out vote buying and the worst thing is that in the first round of the 2018 elections, in Cali, at least 3,230 dead people’s ballots were identified and ended up voting and influencing the results of the first round by the presidency of the republic, This leads us to think that in Colombia democracy in terms of the popular vote is not transparent.

The highest participation recorded in the recent history of the country occurred in the 2018 presidential elections with 54% of the electoral roll, according to a study conducted by the National Civil Status Registrar's Office and the Agustín Codazzi Geographic Institute.

According to the same study, which compared the levels of electoral participation in the presidential elections held in Colombia so far in the 21st century, abstention in the 2002 elections was 54%, in 2006 55.3%, in 2010 56.1% and in 2014 it was 52.6%. According to the report, abstention in 2010 was the highest in the last century.

the mechanisms of citizen participation enshrined in article 103 of the Colombian political constitution and its regulation in the statutory law 1757 of 2015 are an important tool for citizens in general since thanks to these we can regulate and control the form of government.

According to article 103 of the Colombian Constitution, "they are mechanisms for the participation of the people in the exercise of their sovereignty: the vote, the plebiscite, the referendum, the popular consultation, the open council, the legislative initiative and the revocation of the mandate”.

We are in a country in which corruption runs through the veins of practically all the people who govern us, it is very difficult to progress when the rights we have as citizens are violated, for these are the ones that allow us to raise our voices and improve ourselves as a nation In this case, there are many citizen participation mechanisms that are violated, in my opinion the one that most incurs corruption is in the vote and the plebiscite because they are the most used and many of the politicians buy votes or deceive people making faulty promises that they will never keep.

On the other hand, I consider that the plebiscite is also one of the participation mechanisms that is most affected because many times the results obtained at the polls are not respected, as in the case of the plebiscite presented by former President Juan Manuel Santo, when the consultation of Colombians if they agreed with La Paz, which at that time won the "NO" but it is rumored that there was too much corruption in this mechanism of citizen participation.

We can also show the same situation with the other mechanism of citizen participation which is the plebiscite where it is evidenced that that person or some group of people who want to continue taking into account the power of sovereignty.

"For the exercise of the right and promoting, protecting and guaranteeing modalities of citizen participation in political, administrative, economic, social and cultural life, and also to control political power, it is necessary to inquire about the aspects of public interest, the institutional offer of instances of participation, the competences established, as well as respecting the decisions taken and being accountable to the communities"  

Now, throughout the centuries and the presidential, governmental, mayoral and other mandates, we have realized the common factor, corruption. This phenomenon has become so natural in the Colombian political and economic sphere, and is nothing more than an obstacle to the development of the country, which in turn affects the correct establishment of the representatives of the citizens, who many times through of vote buying, corrupt alliances or silencing, of those who use various methods of expression, from the mechanisms that are established within the Colombian Penal Code, to the current technological tools for communication, thus violating the rights, directly and indirectly from all citizens and participants of Colombian society. 

Like the violation of the plebiscite, firstly due to lack of information available to the people involved in the decision or that the people involved in the decision can find out and secondly the value that is given to it, and we have been able to see what is subtracted from the voice of the Participants, who often indicate a certain specific reason and without any argument, the decision that we see in the news and are made by the great leaders, are aimed at individual self-benefit and do not go according to the decision-making expressed by the citizens.
