The recent ruling by the United States Supreme Court regarding Donald Trump's presidential immunity creates a significant legal precedent. For the first time in American history, the Supreme Court defined the limits of immunity for former presidents, stating that the immunity would be "partial". This means that the former president has full immunity for actions he performed in his official capacity, but he does not have immunity for actions he performed in a private setting. 

The decision was made by a majority of six conservative judges against three liberal judges. 

Chief Justice John Roberts wrote in his opinion that under the constitutional structure of the United States, a former president needs some immunity from criminal prosecution for official actions. However, Roberts added, lower courts will have to determine whether or not Trump's actions in the Capitol riots were within the scope of his official duties.
