Things are simpler than this, people voted and the elections had NO fraud.
The polling machines print results and the opposition candidate collected the receipts and organized them in a web page where with over 80% of total polling stations we can verify that Maduro lost.
The electoral council denied access to the machines print out, memory dumps and data transmission over secure lines to their servers.
At the same time this entity proclaimed Maduro the winner without providing any support to how and where the casted votes added up.
People went out to protest in peace that these are not the results and there are now over 900 people detained without crime and due process. All adding up to the 300 political prisoners all in under one week.
We're not asking to overturn the elections but to respect the will of the people. If he lost the popular vote needs to hand over power and step down.
Anything short of that is straight up anti democratic and makes him officially a dictator.
