If it can be proven that this witness lied then the grant of immunity is null and void. The witness can be tried for purjury and if he was a member of the original group, he testitied against, he can be tried for that too. These lies must have substance. For example, if he says the car was black, but it was really a dark blue that would not count. However, if he said I met with the ringleader on Monday, Sept 16th and it can be proven that the ringleader could not have met with him on that date, that would have substance. Also, if you can prove that the gov attorney knew that the witness lied, you can have the attorney disbarred and sue the government. My advise is to get an attorney to discuss your rights with.
If he gave false witness, that's perjury and could result in the revocation of his grant of immunity. Evidence must exist that proves this is false testimony; otherwise it is merely your word against his. Bring your concerns to the state prosecutor's office, along with any evidence you may have to back up your concern. If you wish to seek retribution and redress for the wrong this person has done you, then seek the advice of a good attorney firm that handles both criminal and civil cases first.
If it can be proven that the individual lied, the prosecutor can file a motion with the court. The requirement for honest answers is a prerequisite for Immunity from prosecution .
