Non-democratic elections
In many of the countries with weak rule of law, the most common reason why elections do not meet international standards of being “free and fair” is interference from the incumbent government. Dictators may use the powers of the executive (police, martial law, censorship, physical implementation of the election mechanism, etc.) to remain in power despite popular opinion in favour of removal. Members of a particular faction in a legislature may use the power of the majority or supermajority (passing criminal laws, and defining the electoral mechanisms including eligibility and district boundaries) to prevent the balance of power in the body from shifting to a rival faction due to an election.
Non-governmental entities can also interfere with elections, through physical force, verbal intimidation, or fraud, which can result in improper casting or counting of votes. Monitoring for and minimizing electoral fraud is also an ongoing task in countries with strong traditions of free and fair elections. Problems that prevent an election from being “free and fair” take various forms.
