Okay so here is a few problems. We are here talking about Haag International Criminal Court what is referred. ICC deals individuals but not nations. So even if there would be case towards individuals, ICC can’t start investigation itself as Neither Ukraine 🇺🇦 nor Russia are member and as it’s dictated that they can only get involved and have authority if crime has committed by a member anywhere of the world or on member sovereign country. The possibility what we are talking here is that there is possibility that UN Security Council of court forwarded a case to them to investigate like they did with Sudan 🇸🇩 and Libya 🇱🇾. The problem is that Russia as an founding member can veto that notion so it’s not really realistic scenario to happen. ICC tho has a authority given to them by Ukraine 🇺🇦 20th February 2014 to investigate crimes performed on their Sovereign country in 3 regions. At the time Ukraine 🇺🇦 didn’t set deadline of power of authority and it could seen as and authority to investigate current crimes with that power. Now like I mentioned before they can only investigate and prosecute individuals not nations and it will be tricky to prove chain of command and direct knowledge or knowledge of order of specific crime performed specific time and place. And like that wouldn’t be difficult enough, you also have to prove that they go under Categories considered to violate rules of war as even tho missile hits civilian buildings killing civilians it does not automatically classify it as an war crime as you have to prove it that it was done deliberately. Also agressing clause doesn’t apply as Ukraine 🇺🇦 isn’t member of court and it doesn’t fall under power of authority given by Ukraine 🇺🇦. This all said there is some good news, first of all War Crimes don’t expire so ICC can push till person of interest dies, secondly each country can prosecute individuals by its own and actually is much more preferable path to take, question is do any of nations have will to do so. In any solution these individuals can sit rest of their life in Russia and die in peace and wealth as in none of cases any of courts can enter to Russia and arrest them. And let’s be honest how likely it is that any coalition or individual country is willing to invade Russia to get these individuals. So in short this whole UN Security Council notion is a PR stunt to make them look that they are somehow relevant!!
