Perjury is the offense of lying while under oath. It can be construed as an obstruction of justice, and because of this, it is taken seriously by Illinois and federal criminal courts. You can be charged with perjury while you are navigating the court system because of another criminal charge or when you are involved in a civil case. Perjury is a criminal offense, and as such, you are advised to work with an experienced criminal defense lawyer to fight your perjury charge.
Any instance of intentionally lying while under oath can be charged as an act of perjury. This goes beyond testimonies given during criminal trials and includes statements made in family court, during bail hearings, and during depositions.
However, not all intentional lies are instances of perjury. For a statement to be deemed an act of perjury, its content must be material to the legal proceeding. So, in a deposition, lying about your relationship with the suspect may be an act of perjury if it would redirect the investigation, whereas giving a false statement about the time you spend using social media or the color of your car are not acts of perjury if they are irrelevant to the investigation....
