Navigating the criminal justice system can be overwhelming, especially after a verdict you disagree with. If you believe errors were made during your trial, you may have grounds for a criminal appeal. Understanding the common reasons for appeals can help you decide whether to talk with a lawyer about one. In this article, we explain the most frequent grounds for criminal appeals in South Carolina, from procedural errors to ineffective assistance of counsel, and the deadlines that can apply.
If you or a loved one is considering an appeal, it is essential to act quickly and seek legal guidance. Appeal deadlines in South Carolina are short, and a late notice of appeal can mean the appeal is dismissed. Contact our Greenville criminal appeals attorneys today for a consultation.

Understanding Criminal Appeals
Criminal appeals give a higher court the chance to review a trial for legal errors. Unlike a trial, where the State must prove every element of the charge beyond a reasonable doubt (In re Winship, 397 U.S. 358 (1970)), an appeal asks whether legal mistakes were made that require relief. Understanding the nuances of criminal appeals can help you navigate this complex process more effectively.
When a defendant files an appeal, they are not presenting their case again to a new jury. They are asking a higher court to examine the record of the trial court proceedings for legal errors, and the record on appeal cannot include matter that was not presented to the trial court (SCACR Rule 210(c)). The appellate court may affirm, reverse, or modify the decision below, or send the case back for further proceedings (SCACR Rule 220(a)). Common grounds for an appeal include procedural mistakes, such as improper admission or exclusion of evidence, incorrect jury instructions, or other errors by the judge.
Two other claims usually do not belong in a direct appeal. Ineffective assistance of counsel, where the defendant’s lawyer did not meet the constitutional standard of Strickland v. Washington, 466 U.S. 668 (1984), is usually raised in a post-conviction relief (PCR) application, which South Carolina allows when a conviction or sentence violates the state or federal constitution, when a sentence exceeds the maximum authorized by law, or when evidence of material facts not previously presented requires vacating the conviction or sentence (S.C. Code Ann. § 17-27-20). A PCR application generally must be filed within one year after the judgment of conviction or after the final decision on appeal, whichever is later, and a claim based on new evidence must be filed within one year after the facts were or could have been discovered (S.C. Code Ann. § 17-27-45). A motion for a new trial based on after-discovered evidence has its own one-year limit under Rule 29(b) of the South Carolina Rules of Criminal Procedure.
Deadlines for a direct appeal are much shorter. A notice of appeal from a conviction in the Court of General Sessions must be served within 10 days after the sentence is imposed, unless a timely post-trial motion under Rule 29(a) stays the time to appeal, and it must then be filed within 10 days after it is served (SCACR Rule 203(b)(2) and (d)(1)(B)). If the notice is not timely filed, the appeal is dismissed (SCACR Rule 203(d)(3)).
The appeals process follows strict rules and requires a detailed understanding of legal principles and precedents, so it is important to talk with a criminal defense attorney as soon as possible.

Legal Grounds for Filing a Criminal Appeal
Common grounds you can raise in an appeal of a criminal conviction include:
Procedural Errors
Procedural errors during a criminal trial can affect the outcome and may provide a basis for an appeal. These errors occur when the court departs from established legal procedures, which can compromise the fairness of the trial and the rights of the defendant. Understanding procedural errors is essential for recognizing when an appeal may be worth exploring.
One common type of procedural error involves the improper admission or exclusion of evidence. If the trial court allows evidence that should have been excluded under the rules of evidence, or excludes evidence that should have been admitted, this can prejudice the jury against the defendant. Another frequent procedural error is incorrect jury instructions. If the judge provides the jury with instructions that misstate the law or fail to cover essential legal principles, the jury’s verdict may be based on a misunderstanding of the law.

Errors can also occur through prosecutorial misconduct, such as the withholding of exculpatory evidence or inappropriate comments made during closing arguments. We discuss those claims below.
An appeal based on procedural errors requires a thorough review of the trial record to identify how the errors occurred and whether they affected the outcome. An error does not always lead to a new trial, because the appellate court decides whether the error requires relief. If you believe procedural errors affected your case, it is important to seek the guidance of a criminal defense attorney who can explain the appellate process.
Jury Misconduct
Jury misconduct is a serious issue that can affect the fairness of a criminal trial and may provide a basis for an appeal. Jury misconduct occurs when jurors behave in ways that violate the court’s instructions or the principles of impartiality and fairness that underpin the justice system. Understanding the different forms of jury misconduct and their impact is important for recognizing when an appeal may be worth exploring.
One form of jury misconduct is an external influence, where jurors are exposed to outside information or contact that can sway their decision-making. This can include exposure to media coverage about the case, receiving information from social media, or being contacted by individuals related to the case. Another type is internal misconduct, where jurors fail to follow the court’s instructions.
Internal misconduct can take various forms, such as discussing the case among themselves before deliberations, conducting their own investigations, or bringing in personal biases that affect their judgment. Jurors who lie during voir dire (the jury selection process) to conceal biases or preconceptions can also raise concerns, because it prevents the selection of an impartial jury.
Jury misconduct can be difficult to prove. Under Rule 606(b) of the South Carolina Rules of Evidence, a juror may not testify about statements made during deliberations or about the effect of anything on a juror’s mind or emotions, and a juror’s affidavit on those matters cannot be received. The rule makes an exception for testimony about whether extraneous prejudicial information was improperly brought to the jury’s attention or whether an outside influence was improperly brought to bear on a juror. Because the record on appeal cannot include matter that was not presented to the trial court, a claim based on information discovered after the verdict may need to start with a post-trial motion in the trial court, which generally must be made within 10 days after sentencing (Rule 29(a) of the South Carolina Rules of Criminal Procedure).
Prosecutorial Misconduct
Prosecutorial misconduct occurs when a prosecutor engages in inappropriate or illegal actions that compromise the fairness of a trial. This misconduct can affect the outcome of a case and can be raised in a criminal appeal. Understanding the forms of prosecutorial misconduct and their potential impact is important for defendants considering their options.
One common form of prosecutorial misconduct is the suppression of exculpatory evidence, also known as a Brady violation. The suppression by the prosecution of evidence favorable to an accused violates due process where the evidence is material either to guilt or to punishment (Brady v. Maryland, 373 U.S. 83 (1963)).
Such actions can deny the defendant a fair opportunity to present a complete defense. Another form is the use of false or misleading evidence. A State may not knowingly use false evidence, including false testimony, to obtain a conviction (Napue v. Illinois, 360 U.S. 264 (1959)). Improper comments during closing arguments, such as statements meant to inflame the jury’s emotions or a prosecutor’s personal opinion about the defendant’s guilt, may also be raised as misconduct.

Prosecutorial misconduct can undermine the fairness of a trial. An appeal based on prosecutorial misconduct depends on what appears in the trial record, such as court transcripts. Materials the State never disclosed are often not in that record, so a claim based on them may need to be raised through the post-conviction procedures described above.
If you believe that prosecutorial misconduct affected your case, consulting with a criminal defense attorney promptly is important. Contact us today to discuss your options for an appeal.
Legal Errors
Legal errors in a criminal trial can affect the fairness and outcome of the proceedings, making them a common ground for a criminal appeal. These errors occur when the court incorrectly applies the law or misinterprets legal principles. Understanding the types of legal errors and their implications is important for defendants considering a challenge to their convictions.
One prevalent type of legal error involves improper jury instructions. During a trial, the judge provides the jury with guidelines on how to interpret the law and apply it to the facts of the case. If these instructions are incorrect or incomplete, the jury may base its verdict on a misunderstanding of the law. For example, an error in explaining the burden of proof or the elements of the charged offense can affect the verdict.

Another common legal error is the erroneous admission or exclusion of evidence. If a judge allows evidence that should have been excluded or excludes evidence that should have been admitted, it can unfairly sway the jury’s decision.
Legal errors can also occur during pre-trial motions and hearings. For instance, if a judge denies a motion to suppress illegally obtained evidence, that ruling can be raised on appeal after a conviction. Errors in sentencing, such as imposing a sentence that exceeds the maximum authorized by law, can also be challenged, and South Carolina’s post-conviction relief statute lists a sentence that exceeds the maximum authorized by law as a ground for relief.
An appeal based on legal errors requires a thorough review of the trial record to identify specific instances where the court’s rulings were incorrect. The appellate court then decides whether the error requires relief.
