For criminal appeals, there were 10,092 in the twelve regional courts of appeal for the year ending March 31, 2025. That was a 7 percent increase. They were part of a total of 40,612 appeals. That count covers federal cases only. State systems, where the great majority of assault prosecutions run, keep their own records and report them separately.
There are sometimes legal errors that affect the case’s outcome. That is why assault convictions are often challenged. These challenges involve whether the defendant intended to inflict harm, whether the conduct involved a threat or physical contact, whether the threat was conditional, and whether the defendant acted in defense of self or others.
Juries are told how the law applies through jury instructions. An error in those instructions can form the basis of a successful appeal.
An Appeal Is Not a Retrial
The description given by the federal court is simple. A person filing an appeal must show that the trial court made an error. Oral arguments do not occur in every case, and most of those that do hear them give each side 15 minutes. It’s different from a trial because no one gives testimony and no new evidence is introduced, nor is there a jury.
That constraint shapes everything else. In an appeal, an appellant cannot simply contest the jury’s verdict. Instead, the appellant must show that a legal error occurred during the proceedings and it was significant enough to have affected the outcome.
Appellate law and criminal trial defense law are two different things, which is why some defense attorneys provide criminal appeal services separately from their trial defense services. A criminal appeals lawyer provides assistance to defendants who want to appeal their convictions, primarily by finding trial errors that the defense team can use to make legal appeals on their clients’ behalf.
Preservation Decides What Survives
A strong appellate issue can be lost before the trial even ends. When counsel fails to object on the record, the appellate court usually applies plain error review. Under that standard, the defendant must show a clear error that affected substantial rights and seriously affects the fairness, integrity, or public reputation of the proceedings.
Where Assault Appeals Actually Turn
The differences in assault definitions matter just as much as the procedure, and they cannot be applied uniformly. For example, an assault charge in Illinois may not be the same charge in other states.
Jury instructions on self-defense come up often in assault appeals. Whether the trial court gave the instruction at all, whether it placed the burden where state law puts it, and whether it addressed a duty to retreat in states that impose one are all reviewable questions with real traction on appeal.
Evidentiary rulings are another common source of appellate issues. These include the admission of earlier incidents between the same two people, the complainant’s statements to responding officers, and medical records offered without testimony from the author. Each of these issues generally requires a timely objection at trial.
Sufficiency challenges are among the hardest to win. The appellate court views the evidence in the light most favorable to the prosecution and asks whether any rational juror could have found each element proven beyond a reasonable doubt.
The Claims That Do Not Fit in a Direct Appeal
Even if they seem most pressing, some claims cannot even be included in the opening brief. Because appeals on direct review are decided on the trial record, claims that rely on facts not in the record cannot be brought in a direct appeal.
Claims that rely on outside facts, like evidence that wasn’t introduced at trial or confidential attorney-client communications, must be brought in a separate post-conviction petition. Of course, each post-conviction proceeding has its own deadline and unique procedures.
This distinction can result in differing processes for appellate review of ineffective assistance claims. Specifically, defendants may find that an appellate court cannot review an ineffective assistance of counsel claim on direct appeal when the trial record contains too little information about the trial attorney’s actions. In these situations, claims may be required to be asserted in separate post-conviction proceedings.
Deadlines are the other thing that ends appeals before they start. A federal criminal defendant generally has 14 days from entry of judgment to file a notice of appeal, and state deadlines vary.
