Lying in Court - Nolo: "Another fact little known to those who don't live in the court system every day is that there is rarely any earthly punishment for lying in court. There is, of course, the crime of perjury. Here is how California defines it (a definition that's pretty typical of those used by other states):
'Every person who, having taken an oath that he or she will testify...truly before any competent tribunal..., willfully...states as true any material matter which he or she knows to be false...is guilty of perjury.'"
