White House officials on Tuesday said President Biden would veto a bipartisan measure creating 66 new federal judicial seats over the next three presidential administrationsdafabet slot, stating that the measure the House is set to take up this week is “unnecessary to the efficient and effective administration of justice.”

In a new statement, the officials, from the Office of Management and Budget, also noted that the legislation, which passed the Senate with no opposition in August, would create new vacancies in states where senators have dragged their feet on filling vacancies during the Biden administration.

“Those efforts to hold open judicial vacancies suggest that concerns about judicial economy and caseload are not the true motivating force behind passage of this bill now,” the statement said.

The veto threat was a blow both to lawmakers who backed the measure and to officials of the federal judiciary who have pressed for years for more judges, citing a tremendous backlog of cases and the lack of a significant expansion of judgeships since 1990. But efforts to add seats have consistently run into political trouble as presidents and members of Congress try to game out who would be in position to name those jurists, an issue that proved again to be a complication for the legislation.

Proponents in both parties reached an understanding this year to approve the judicial legislation before the Nov. 5 election, so that lawmakers in both parties would be voting on it without knowing who the next president would be. It passed the Senate without any opposition in August.

But the bill sat idle in the Republican-controlled House until Donald J. Trump won, providing the G.O.P. with new incentive to pass it even as Senate Democrats are racing to fill as many judicial vacancies as possible with Mr. Biden’s nominees to deny Mr. Trump the chance.
