This is against democratic principles. The consequences of not accepting the result of an election may be a government that is ineffective and cannot make decisions. It may even result in violence which is also against democracy. All democracies strive to respect and protect the human rights of citizens. Human rights mean those values that reflect respect for human life and human dignity.
Democracy emphasizes the value of every human being.
Examples of human rights include freedom of expression, freedom of association, freedom of assembly, the right to equality and the right to education. In order to have a multi-party system, more than one political party must participate in elections and play a role in government. A multi-party system allows for opposition to the party, which wins the election. This helps provide the government with different viewpoints on issues. Additionally, a multi-party system provides voters with a choice of candidates, parties and policies to vote for.
