Roberts is a strong proponent of stare decisis, believing that even some wrongly decided cases should not be overturned,[10] as well as a staunch defender of the Court's reputation.[11][3] Since 2018, the Court's ideological makeup with respect to abortion rights shifted, with Neil Gorsuch and Brett Kavanaugh's appointments alongside Samuel Alito and Clarence Thomas.[11] Several Republican-majority states passed bills restricting abortions, anticipating a potential legal shift from the Supreme Court and providing possible case vehicles for bringing the issue to the Supreme Court.[13] When Amy Coney Barrett replaced Ruth Bader Ginsburg, the Court's ideological makeup shifted further and created an opportunity to overturn or additionally limit Roe.[5][13][14] Ginsburg had generally been in the majority of past Supreme Court cases that enjoined stricter abortion laws.
