Upon further review is a phrase used to describe the process of taking a second look at something, usually in order to make a more informed decision. It is often used in legal contexts, where a judge or other authority may review evidence or testimony to determine the truth of a matter. It can also be used in other contexts, such as when a business reviews its policies or procedures to ensure they are up to date and effective. In any case, UPON further review implies that a more thorough examination is necessary before a final decision can be made.
