Explanation:

Ukraine has filed an application before the International Court of Justice (ICJ), instituting proceedings against the Russia concerning “a dispute relating to the interpretation of the 1948 Convention on the Prevention and Punishment of the Crime of Genocide” (the “Genocide Convention”).

• Ukraine has accused Russia of falsely claiming that “acts of genocide have occurred in the Luhansk and Donetsk oblasts of Ukraine”, and of using that as a pretext to recognise the independence of these regions and of going to war against Ukraine.
• The ICJ is the principal judicial organ of the United Nations (UN).
• Like the PCIJ, the ICJ is based at the Peace Palace in The Hague. It is the only one of the six principal organs of the UN that is not located in New York City.
• The ICJ has 15 judges who are elected to nine-year terms by the UN General Assembly and Security Council, which vote simultaneously but separately.
• Timeline
• It was established in June 1945 by the Charter of the United Nations and began work in April 1946.
• The court is the successor to the Permanent Court of International Justice (PCIJ). The PCIJ was formally dissolved in April 1946, and its last president, Judge José Gustavo Guerrero of El Salvador, became the first president of the ICJ.
• The first case, which was brought by the UK against Albania and concerned incidents in the Corfu channel — the narrow strait of the Ionian Sea between the Greek island of Corfu and Albania on the European mainland — was submitted in May 1947.

Hence only statement 1st is correct.
