Trump’s lawyers turned to the nation’s highest court on Wednesday after New York courts refused to postpone the sentencing by Judge Juan M. Merchan, who presided over Trump’s trial and conviction last May on 34 felony counts of falsifying business records. Trump has denied wrongdoing.

Prosecutors were expected to file a response by Thursday morning.

Trump’s team sought an immediate stay of the scheduled sentencing, saying it would wrongly restrict him as he prepares to take office. While Merchan has indicated he will not impose jail time, fines or probation, Trump’s lawyers argued a felony conviction would still have intolerable side effects.

The sentencing should be delayed as he appeals the conviction to “prevent grave injustice and harm to the institution of the Presidency and the operations of the federal government,” they argued.

The emergency motion is from lawyers John Sauer, Trump’s pick for solicitor general, who represents the government before the high court, and Todd Blanche, in line to be the second-ranking official at the Justice Department.

They also pointed to the Supreme Court ruling giving Trump and other presidents broad immunity from prosecutions over their actions in office, saying it supports their argument that his New York conviction should be overturned.

Their filing said the New York trial court “lacks authority to impose sentence and judgment on President Trump — or conduct any further criminal proceedings against him— until the resolution of his underlying appeal raising substantial claims of Presidential immunity, including by review in this Court if necessary.”

The Republican president-elect’s spokesman, Steven Cheung, said in a statement that the case was politically motivated and should be dismissed.

Trump’s lawyers also asked New York’s highest court for an emergency stay to halt all proceedings Wednesday afternoon, urging quick action to avoid the threat of disrupting the presidential transition.

In a filing that largely echoed their Supreme Court arguments, the attorneys charged that Merchan and the state’s mid-level appellate court both “erroneously failed” to stop the sentencing, arguing that the constitution requires an automatic pause as they appeal the judge’s ruling upholding the verdict.

The Manhattan district attorney’s office, meanwhile, said it will respond in court papers. The emergency motion was submitted to Justice Sonia Sotomayor, who hears appeals from New York.

Trump’s convictions arose from what prosecutors said was an attempt to cover up a $130,000 hush money payment to porn actor Stormy Daniels just before the 2016 presidential election.

Daniels claims she had a sexual encounter with Trump in 2006. He denies it.

The Supreme Court’s immunity opinion came in a separate election interference case against him, but Trump’s lawyers say it means some of the evidence used against him in his hush money trial should have been shielded by presidential immunity. That includes testimony from some White House aides and social media posts made while he was in office.

Merchan has disagreed, finding they would qualify as personal business. The Supreme Court’s immunity decision was largely about official acts of presidents while in office.
