What happens when evidence is improperly admitted or excluded?

• A. It can form the basis for an appeal or for setting aside a conviction if it affected the outcome.
• B. It has no effect on the case.
• C. It always leads to immediate acquittal.
• D. It guarantees a retrial in all cases.

Answer: (A)

When a trial ruling on evidence goes wrong, the key question is whether the mistake could have changed the verdict. If the improperly admitted evidence or the excluded evidence likely affected the outcome, that error becomes a basis for appeal and can lead to setting aside the conviction or ordering a new trial. It’s not automatic acquittal or retrial in every case—the remedy hinges on whether the error was prejudicial; harmless mistakes may not affect the result, while prejudicial errors that could have changed the outcome warrant relief.
