My belief is that no one has the right, or the legal and constitutional power, to annul the elections based on campaign influence. The law only specifies a right to annul one election (a specific day, not the whole process as was done here), and then only if the voting process itself is corrupted (miscounting votes, stopping people from voting, physically coercing people to vote, etc).
The regular court system can pursue individuals who conspired with Russia (including, likely, Călin Georgescu himself!), prosecute and try them for treason.
Intelligence services and electoral authorities have the power to stop the interference while it is in progress, by forcing people and sites to take it down, banning entire domains if they don't comply, arresting people who are coordinating with foreign nationals, etc.
The election will be done again, and people can vote their favorite person again, this time with the full knowledge of who is behind them.
It sucks that authorities did nothing before the elections, but I suspect that disqualifying the fascist guy because of fraud and interference would have produced the exact same complains from his fans and the Ruzzian trolls.
Right? You would claim that he should be allowed to continue until the courts will decide it was fraud, and until the appeals are done and until the complains to the EU court are also complete.
