The Security Council has rarely used its full power to take action against violators because c) problems of power politics, member self-interest, and free rider problems meant that major decisions have more often been left to ad-hoc tribunals instead
What is the justification?
Although the United Nations charter forbids member states from using force unless necessary for self-defense or collective security, the Security Council has hardly ever employed its full authority to prosecute offenders. This can be ascribed to a number of things, such as the issues with free riders, member self-interest, and power politics.
