The debate comes at a time when conflicts are multiplying, global tensions are rising and trust in international institutions and norms is waning, even as the UN marks 80 years since the adoption of its founding Charter, which established principles aimed at preventing wars and reducing suffering.
“The rule of law is a cornerstone of global peace and security,Guterres said, calling it “the beating heart” of the United Nations Charter.
For eight decades, he said, the Charter, together with the Universal Declaration of Human Rights, the Geneva Conventions and other fundamental legal instruments, have helped humanity avoid another world war and limit the cost of countless conflicts.
Egregious violations
But the Secretary General warned that commitments to international law are increasingly being ignored.
“Around the world, the rule of law is being replaced by the law of the jungle,” he said, pointing out what he described as flagrant violations of the United Nations Charter and international law, including the illegal use of force, attacks on civilian infrastructure, human rights abuses and the denial of life-saving humanitarian aid.
From Gaza to Ukraine and beyond, he said, the rule of law is being treated like “an a la carte menu,” with states choosing which rules to follow. He warned that such violations set dangerous precedents, encourage impunity and erode trust between nations.
A lifebuoy and a handrail
For smaller, less powerful countries, particularly those affected by historical inequalities and the legacies of colonialism, international law is “a lifeline that promises equal treatment, sovereignty, dignity and justice,” Guterres said.
“For powerful countries, it is a barrier that defines what is acceptable and what is not, in times of disagreement, division and open conflict,” he added.
He underlined the sole responsibility of the Security Council, the only body with authority established by the Charter to make decisions binding on all Member States and authorize the use of force under international law.
“Your responsibility is singular. Your obligation is universal,” he stated.
Action priorities
Looking ahead, the UN chief outlined three priority areas for action.
First, he urged countries to fulfill the commitments they made under the Charter, including the peaceful settlement of disputes, the safeguarding of human rights and respect for the sovereign equality of States.
Secondly, it called for the use of peaceful tools to resolve disputes (negotiation, mediation and judicial settlement, along with stronger partnerships with regional organisations) and more investment in development to address the root causes of inequality and exclusion.
Thirdly, he highlighted the need for fair and independent judicial procedures. It encouraged greater reliance on independent courts and tribunals, including the International Court of Justice (ICJ), and greater support for international criminal justice.
“There can be no sustainable or just peace without accountability,” Guterres said. “The rule of law must prevail.”
