The Supreme Court of Nevada has rejected an appeal from US President Donald Trump's campaign to overturn the election results in the state, affirming President-elect Joe Biden's win in one of the battleground states that gave him overall victory.
It was the latest court failure for Mr Trump and his allies, who have lost dozens of cases in state and federal courts in an unsuccessful attempt to nullify the result of the 3 November election.
Mr Trump says the result was fraudulent, but no court has found evidence to support his assertions.
Last week, a district court in Nevada ruled that the Trump campaign had not proven a claim that there had been a malfunction in voting devices and the contest between Mr Trump and Mr Biden had been manipulated.
"We also are not convinced that the district court erred in applying a burden of proof by clear and convincing evidence, as supported by the cases cited in the district court's order," Nevada's Supreme Court said in its judgment.
Nevada's Republican Party said it was "extremely disappointed" by the decision.
"We were not afforded an opportunity to write our brief or argue the case in front of the Court," Nevada's GOP said in a statement.
"Full denial of legitimate due process and appellate rights is truly unprecedented, shocking and extraordinary."
Mr Biden won Nevada by a 33,596-vote margin, giving him the state's six votes in the Electoral College which choses the president.
The electors are scheduled to meet on 14 December to formalise the outcome, with Mr Biden having won 306 votes to 232 for Mr Trump.
Yesterday was marked as the so-called "safe harbour" deadline for states to resolve disputes arising from the election.
Under US law, Congress will consider a state's election result to be "conclusive" if it is finalised by the safe harbour date.
