The purpose of this legislation, known as the "End Russian Oil Windfalls Act," is to counteract the financial benefits that Russia may gain from selling oil and petroleum products, particularly to India. The act aims to nullify specific licenses that allow for the sale and delivery of Russian crude oil and petroleum products, thereby tightening sanctions against Russia in response to its actions. Key provisions of the act include the immediate nullification of two specific licenses that permit the sale of Russian oil to India.
