Hunter Biden’s federal tax evasion trial will go forward next month — after a California judge tossed the first son’s latest attempt to get the case dismissed.

The trial accusing President Biden’s already felon son will begin Sept. 9 in Los Angeles court. He’s accused of failing to pay $1.4 million in taxes from 2016 to 2019.

Hunter’s legal team asked Los Angeles Judge Mark Scarsi to dismiss the three felony and six misdemeanor tax charges he faces on the grounds that David Weiss’ appointment to prosecute the case as special counsel was unconstitutional and Weiss — a Delaware US attorney — doesn’t have jurisdiction to oversee the California case.

The motion prompted Scarsi to threaten sanctions against the Biden son’s lawyers for lying about Weiss’ involvement in the probes against Hunter.

Hunter’s attorneys responded by claiming they didn’t intentionally lie but rather misused a single word two times.

Scarsi — who has rejected three prior bids by Hunter to have the case dismissed, including over Weiss’ appointment — canned the latest motion to dismiss on Monday. He said Hunter’s team didn’t raise any new legal issues and that the latest motion comes too late.

Hunter’s team kicked up a fuss about Weiss’ appointment again last month, claiming that a bombshell ruling dismissing the documents case against former President Donald Trump over special counsel Jack Smith’s appointment should apply in Hunter’s case too.

But Scarsi called the Trump ruling “non-binding” — meaning it’s not applicable to this case.

Hunter has pleaded not guilty in the case.

Hunter was separately convicted in June for illegally owning a gun while hooked on drugs and is set to be sentenced on Nov. 13. He faces up to 25 years behind bars in the Delaware case, which Weiss also prosecuted.

A spokesperson for Weiss’ office declined to comment. Hunter’s lawyers didn’t immediately return a request for comment Wednesday.
