We all know that it is perjury to give false testimony under oath, a serious crime. What some people don’t realize is that it’s also a crime to present any fictitious evidence in a legal proceeding.
Stated in California Penal Code 132, the crime of offering false evidence makes it illegal to present any false written evidence – if your purpose is to deceive the court into believing it to be true.
In the DUI context, this might include someone submitting false receipts for alcohol – trying to make the court believe you drank less than you really did. Or it could include phony or doctored medical records suggesting you have a health condition that affected your ability to perform the field sobriety tests.
