Law of the case

Within a single case, once there has been a first appeal, both the lower court and the appellate court itself will not further review the same issue, and will not re-review an issue that could have been appealed in the first appeal. Exceptions are limited to three "exceptional circumstances": (1) when substantially different evidence is raised at a subsequent trial, (2) when the law changes after the first appeal, for example by a decision of a higher court, or (3) when a decision is clearly erroneous and would result in a manifest injustice. This principle is called " law of the case ".
