The Guardian view on Trump and presidential immunity: the return of the king | Editorial

The supreme court's sweeping ruling is a blow to democracy in the US

The supreme court's ruling on presidential immunity combines a tectonic constitutional shift and immediate political repercussions to devastating effect. It allows one man to stand above the law. It slows and appears to gut the 2020 election-subversion case against Donald Trump, though it does not necessarily end it. No one believes a trial can be held before November's election, although court hearings could still offer a detailed airing of the evidence thisautumn.

There could hardly have been a better week for Mr Trump, who saw his rival stumble so badly in last Thursday's debate that Joe Biden faces growing calls to quit four months from election day. Anyone who doubts how consequential a second Trump administration term would be for the United States and the world need only look to the supreme court, now ruled by a conservative supermajority thanks to three Trump-appointed justices.
