WASHINGTON (REUTERS) - The United States Supreme Court on Friday (Dec 11) brought an abrupt end to a long-shot lawsuit filed by Texas and backed by President Donald Trump seeking to throw out voting results in four states, dealing him a crushing setback in his quest to undo his election loss to President-elect Joe Biden.
The justices in a brief order rejected the bid by Texas to file the extraordinary challenge targeting Georgia, Michigan, Pennsylvania and Wisconsin directly with the Supreme Court, as is allowed in some instances of litigation between states under a legal doctrine called "original jurisdiction".
The case was filed on Tuesday by the Republican attorney general of Texas, a Trump ally. The Republican President on Wednesday filed a motion to intervene and become a plaintiff.
The Supreme Court's 6-3 conservative majority includes three justices appointed by Mr Trump and none of them commented in the unsigned order. Before the Nov 3 election, Mr Trump said he expected its outcome to be decided by the Supreme Court.
"Texas has not demonstrated a judicially cognisable interest in the manner in which another state conducts its elections," the court's order said.
Two of the court's conservatives, Justice Samuel Alito and Justice Clarence Thomas, said they would have allowed Texas to sue but would not have blocked the four states from finalising their election results.
There was no immediate response from the White House. A Biden spokesman said it was "no surprise" the high court rejected "baseless attempts" to deny Mr Trump lost the election.
"Our nation's highest court saw through this seditious abuse of our electoral process," Pennsylvania Attorney General Josh Shapiro, a Democrat, said on Twitter.
The four states in a filing with the court on Thursday asked the justices to reject the lawsuit, which they said had no factual or legal grounds.
Mr Biden won all four states. In 2016, Mr Trump had won them.
Mr Trump's campaign and his allies have lost in numerous lawsuits in state and federal courts challenging this year's election results.
Mr Trump has falsely claimed he won the Nov 3 election and has made baseless allegations of widespread voting fraud and a system "rigged" against him. State election officials have said they have found no evidence of such fraud.
Lawyers for Mr Trump and his allies have failed to present evidence in court of the type of fraud he has alleged. Texas has asked the justices to throw out the election results in the four states. Mr Biden won all four states.
Mr Trump had won them in the 2016 election. He and many of his fellow Republicans have made unfounded claims that the expansion of mail-in voting during the coronavirus pandemic led to Mr Biden fraudulently winning in election battleground states.
Democrats and other critics have accused Mr Trump of seeking to shatter public belief in the integrity of US elections and sabotage American democracy by trying to subvert the will of the voters.
Mr Trump has refused to concede the election and many Republicans have not acknowledged Mr Biden as president-elect. Mr Biden is due to take office on Jan 20.
The Texas lawsuit argued that changes made by the four states to voting procedures amid the coronavirus pandemic to expand mail-in voting were unlawful.
Texas asked the Supreme Court to immediately block the four states from using the voting results to appoint presidential electors to the Electoral College, which is scheduled to formally pick the winner on Monday.
