If it can be "proven" (beyond a reasonable doubt) that a person lied while on the witness stand, it is possible the person could be charged with Perjury. If a person lied to police officers when reporting an alleged crime, that person could be charged with "false reporting". If it has been three months since the alleged 'lying", and nothing has happened, it is likely nothing will happen, but they do have up to three years to file felony charges and up to 18 months to file misdemeanor charges. But, like I said, if it has not happened yet, it seems unlikely they will file charges.
