Actually, it means a bit more than that.
"Should the judge decline to remove herself, legal experts said Trump could seek to have the decision reviewed and petition the US court of appeals for the DC circuit for a writ of mandamus, a judicial order to a lower-court judge compelling an action such as recusal.
The appeal could be accompanied with a motion to stay Chutkan’s rulings pending appeal, which could delay the pre-trial process and push back the current trial date set for March 2024 while that litigation continues."
Delays are particularly meaningful for these Trump trials.
