International Criminal Court Prosecutor Karim Khan has said they are committed to showing the world that justice at their level is not" hot air".
In an interview with TV 47 on Friday, Khan said the warrant of arrest for Russian President Vladimir Putin has the quality of a judicial order.
According to Legal Information Institute, a judicial order is a decision issued by a court or an authoritative body.
Khan issued the arrest warrant for President Putin in March 2023.
It alleged the Russian President is responsible for war crimes and has focused its claims on the unlawful deportation of children from Ukraine to Russia.
It says the crimes were committed in Ukraine at least from February 24, 2022 - when Russia launched its full-scale invasion in Ukraine.
An arrest warrant was also issued for Russia's commissioner for children's rights Maria Lvova-Belova.
On Friday, Khan said before it was issued, the ICC independent judges reviewed his warrant application and agreed with the assessment that the standard of evidence was sufficient for issuance.
"I have been trying my best and I have given an undertaking God willing that we will not be bringing cases that are not strong," he said.
"This is the time that we have to show international justice is not hot air and false promises. There is a foundation to it."
Khan expressed confidence in that there is a foundation in the arrest warrant for Putin.
"Now it is for us to make sure that we can do our job in all situations of the world because every human life matters equally," he added.
Khan said even though he respects the role of the Russian Federation, which is a permanent member of the United Nations Security Council, the law must apply in the most effective way -"the law must apply as effectively as possible as far as possible".
He pointed out that the Hague-based court is one of the last resort and justice should be done at home.
"But if there is no justice, if there is no determined effort to vindicate the rights of the most vulnerable; the youngest children, the most vulnerable boys and girls, and women and men, the old and the sick, then international standards must try to apply in this very imperfect world as effectively as possible," the ICC Prosecutor said.
He went on to give examples of top political leaders who were arrested and detained- in a show of the presence of justice- including former Prime Minister of Rwanda Jean Kambanda and former President of Liberia Charles Taylor.
Kambanda is serving a life sentence at the Koulikoro Prison in Mali for genocide while Taylor was convicted of crimes against humanity including murder, terrorism and rape.
He is serving 50 years in a prison at Durham, United Kingdom.
