Lawyers for former President Donald J. Trump asked a federal judge on Wednesday to put the proceedings on hold in the case charging him with seeking to overturn the 2020 election as they appeal her recent ruling that he is not immune from prosecution.

The request to freeze the case as the appeal goes forward was part of a long-planned strategy to delay any trial on the election interference charges from starting on schedule, in March.

Mr. Trump’s legal team is hoping that a protracted appeal of the immunity issue, potentially to the Supreme Court, could result in the trial being pushed off until after the 2024 election is decided. Barring that, his lawyers hope to postpone the trial at least until after the Republican Party holds its nominating convention in Milwaukee in July.

The way in which appealing the judge’s ruling has become entangled with Mr. Trump’s political calendar is typical of the way he has handled all four of the criminal cases he is facing as he mounts his third bid for the White House. He and his aides have made no secret that they believe his best shot at disposing of the four indictments against him is to be re-elected.
