Yes, a judge can change their mind after a ruling, but the path depends almost entirely on when you ask. Before a final judgment, judges have broad authority to revisit their own orders. After final judgment, a party has to file a specific motion within a strict deadline and meet narrow grounds. In criminal cases, one ruling is untouchable no matter what: an acquittal. So the real question behind whether a judge can change his mind after a ruling is which stage the case is in and which motion fits.
Before Final Judgment, the Judge Has Wide Latitude
If the case is still in progress, meaning the court has not yet entered a final judgment resolving every claim against every party, the judge can revise earlier rulings freely. Federal Rule of Civil Procedure 54(b) allows revision of any order that resolves fewer than all the claims or parties at any point before that final judgment.1Legal Information Institute. Federal Rules of Civil Procedure Rule 54 – Judgment; Costs Pretrial evidentiary rulings, orders on motions to dismiss, and summary judgment decisions that leave some claims alive all fall in this category.
A pretrial ruling against you is not necessarily locked in. As trial develops and new facts emerge, the judge can reconsider without the moving party having to clear the high bar that applies after final judgment. Courts generally revisit interlocutory orders when substantially different evidence surfaces, the applicable law changes, or the earlier ruling was clearly wrong in a way that would produce an unjust result.
Fixing Clerical Errors Has No Deadline
The simplest change is correcting a mistake in how the ruling was written down. A clerical error is a typo, a math slip, or an omission in the documentation, not a disagreement with the reasoning. If the judge meant to award $50,000 and the order says $5,000, that is clerical. If the judge awarded $50,000 and you believe it should have been $500,000, that is substantive and requires a different motion.
Federal Rule of Civil Procedure 60(a) lets a court correct clerical mistakes at any time, on its own or at a party’s request.2Legal Information Institute. Federal Rules of Civil Procedure Rule 60 – Relief from a Judgment or Order No deadline, no formal motion always required. Courts sometimes use a nunc pro tunc order for this, making the record reflect what the court originally intended.
Formal Motions to Change a Civil Ruling
Once final judgment is entered, changing a ruling means filing a post-trial motion directed to the same judge. In federal court, the two main vehicles are Rule 59 and Rule 60(b), and they do different jobs.
Rule 59: Alter the Judgment or Get a New Trial
A motion under Rule 59(e) to alter or amend the judgment fits when the court overlooked controlling law, misapplied a legal standard, or failed to account for evidence already in the record. It is not an opportunity to re-argue the case. Courts grant these motions when the moving party identifies a clear error that would change the outcome.
A motion for a new trial under Rule 59(a) goes further, arguing that problems during the trial itself were serious enough that starting over is the only fair remedy. Grounds include improper jury instructions, prejudicial evidence that should have been excluded, or a verdict so against the weight of the evidence that it shocks the conscience. Both types of Rule 59 motions must be filed within 28 days after entry of judgment.3Legal Information Institute. Federal Rules of Civil Procedure Rule 59 – New Trial; Altering or Amending a Judgment Miss that window and the motion is dead.
Rule 60(b): Relief From a Final Judgment
Rule 60(b) is the broader safety valve for situations where enforcing the judgment as written would be fundamentally unjust. The grounds are specific:
- Mistake, inadvertence, surprise, or excusable neglect.
- Newly discovered evidence that could not have been found earlier through reasonable diligence and would likely change the outcome.
- Fraud, misrepresentation, or misconduct by the opposing party.
- A void judgment, meaning the court lacked jurisdiction over the parties or the subject matter.
- A prior judgment the ruling relied on has been reversed or otherwise vacated.
- Any other reason justifying relief, a catch-all reserved for genuinely extraordinary circumstances.
Courts read these grounds narrowly. The catch-all is not a back door for rearguing the merits; it is meant for situations like a party who was incapacitated and unable to participate in the proceedings.2Legal Information Institute.

The Deadlines That Decide Everything
Timing here is unforgiving. Rule 59 motions to alter the judgment or request a new trial must be filed within 28 days of entry of judgment.3Legal Information Institute. Federal Rules of Civil Procedure Rule 59 – New Trial; Altering or Amending a Judgment
Rule 60(b) has a two-tier structure. Every Rule 60(b) motion must be filed within a “reasonable time.” For the first three grounds (mistake, newly discovered evidence, and fraud) there is also a hard cap of one year after entry of judgment. For the remaining grounds (void judgment, reversed prior judgment, and the catch-all) there is no fixed outer limit, but “reasonable time” still applies, and motions filed years later without a good reason will be denied.2Legal Information Institute. Federal Rules of Civil Procedure Rule 60 – Relief from a Judgment or Order
One detail trips people up. Filing a Rule 60(b) motion does not pause enforcement of the judgment; the judgment stays in effect while the motion is pending.2Legal Information Institute.

Criminal Cases: Different Rules, Much Tighter
Criminal proceedings run on their own set of rules, and some are far more restrictive than anything in civil litigation.
An Acquittal Cannot Be Undone
If a jury returns a not-guilty verdict, no judge can overturn it and no prosecutor can retry the defendant on the same charge. The Fifth Amendment’s Double Jeopardy Clause provides that no person shall “be subject for the same offence to be twice put in jeopardy of life or limb.”4Constitution Annotated. Amdt5.3.1 Overview of Double Jeopardy Clause The Supreme Court has called the inviolability of acquittals the most fundamental rule in double jeopardy law. That holds even if the verdict appears to rest on a mistake or on jury bias.
Convictions and New Trials
Guilty verdicts have no such absolute protection. A convicted defendant can move for a new trial under Federal Rule of Criminal Procedure 33 when “the interest of justice so requires.” A motion based on newly discovered evidence must be filed within three years of the guilty verdict. Every other ground has a 14-day deadline.5Legal Information Institute. Federal Rules of Criminal Procedure Rule 33 – New Trial That 14-day window is far shorter than its civil counterpart, and missing it usually ends the matter.
Changing a Sentence
A judge’s power to change a sentence after pronouncing it is narrow. Federal Rule of Criminal Procedure 35 lets the court correct a sentence that resulted from an arithmetic, technical, or other clear error, but only within 14 days of sentencing. After that, the only route to a reduced sentence is a government motion certifying that the defendant provided substantial assistance in investigating or prosecuting someone else, generally filed within one year of sentencing, with narrow exceptions for information not available or useful sooner.6Legal Information Institute. Federal Rules of Criminal Procedure Rule 35 – Correcting or Reducing a Sentence
How This Differs From an Appeal
Every motion above goes back to the same judge who issued the ruling. You are asking that judge to acknowledge an error or respond to changed circumstances. An appeal is a different process entirely. It moves the case to a higher court, where appellate judges review the trial court’s existing record for legal mistakes. Appellate courts do not hear new evidence or retry the facts.
Post-trial motions are typically faster and cheaper, and they sometimes succeed because the trial judge recognizes an oversight once it is pointed out. Appeals are slower, more expensive, and reviewed under deferential standards that make them harder to win. Common practice is to file the appropriate post-trial motion first, both to preserve issues for appeal and to give the trial court a chance to fix its own mistake.
Post-Trial Motions Can Reset the Appeal Clock
The interaction between post-trial motions and appeal deadlines is one of the most consequential details in litigation. Under the Federal Rules of Appellate Procedure, a timely motion for a new trial under Rule 59, a timely motion to alter or amend the judgment under Rule 59, or a Rule 60 motion filed within the Rule 59 time period pushes back the appeal deadline. The clock does not begin running until the court disposes of the last remaining motion.7Legal Information Institute. Federal Rules of Appellate Procedure Rule 4
The reverse also matters. If you file a notice of appeal while a qualifying post-trial motion is still pending, that notice is effectively suspended and does not become operative until the court enters an order resolving the motion.7Legal Information Institute. Federal Rules of Appellate Procedure Rule 4 Getting the sequence wrong is where appellate rights get forfeited.
