Explanation

In a constitutional democracy, accountability is best enforced through a system of checks and balances. This system ensures that no single branch of government (executive, legislature, or judiciary) becomes too powerful. Each branch has the ability to limit the actions of others, preventing abuses of power and promoting accountability. While civil society organizations and the selection of the right leaders are important, checks and balances are the primary mechanism for enforcing accountability within the structure of government.
