Harmless error
Harmless error refers to a legal doctrine that holds that certain mistakes made during a trial should not lead to the reversal of the trial's outcome, as long as those mistakes do not significantly affect the proceedings or infringe upon the constitutional rights of the involved parties. This principle is important in appellate courts, which review trial decisions, as it allows them to dismiss minor errors that do not alter the overall fairness or result of the trial. For instance, if a prosecutorial mistake, like admitting improperly obtained evidence, occurs but is determined to have not influenced the jury's decision, the conviction may still stand. The concept emerged in response to historical instances where trivial errors led to unjust reversals of convictions, highlighting the need for a more balanced approach to judicial review. Harmless error became recognized and codified in U.S. law in the early twentieth century, with formal inclusion in legislation and procedural law by the mid-1900s. This doctrine seeks to uphold the integrity of the judicial process while ensuring that minor oversights do not undermine the pursuit of justice.

SIGNIFICANCE: The principle of harmless error holds that mistakes made by prosecutors should not be the basis of reversing trial results on appeal, if those mistakes do not significantly alter court proceedings or outcomes or substantially violate the constitutional rights of the parties.
If a legal mistake, or error, is made during a trial, the results of the trial often may be reversed on appeal. For example, a conviction may be overturned by an appellate court for such a prosecutorial error as admitting illegally seized evidence into trial. However, if the error is a minor mistake that can be proven beyond a reasonable doubt not to influence the outcome of the trial or create prejudice against the defendant, the error may be considered “harmless,” and the trial result will be allowed stand. The principle of harmless error prevents appellate courts from overturning judicial decisions for unimportant courtroom mistakes.
During the early twentieth century, convictions were sometimes reversed for errors as trivial as omitting the word the from “peace and dignity of the state” at the end of an indictment. Recognizing the need for “harmless error,” the U.S. Congress began including it in legislation in 1911. In 1948, harmless error was added to procedural law.
