Is perjury committed during depositions punishable in SC and how does one press charges?

Depositions are sworn documents (i.e.: taken under oath). If the person being deposed knowingly perjures themslves (gives false answers) during their deposition they may be cited for lying under oath, but an individual, themselves, may not 'press charges' over it. If the contents of the deposition are used in court you, or your attorney, must impeach the witness during verbal examination, and then ask the judge to hold the witness iin contempt.
