While I think 525601minutes overstates the case, the judge did hear the testimony. Had the judge believed a perjury prosecution was appropriate the judge could have referred the matter to the prosecutor's office for review. But consider: perjury charges are rare in non-criminal cases (and even within that context they're pretty rare); the fact that a judge disbelieved testimony does not of itself mean that perjury occurred; and the fact that testimony is not credible does not mean that it will automatically be possible to prove that it rises to the level of perjury.
Also, statements made in an unsworn pleading cannot be perjury as they are not made under oath. Is that what we're talking about here? Something on a piece of paper, but not actual sworn statements or testimony?
If this was a sworn statement you can try talking to somebody in the prosecutor's office, perhaps a victim's rights officer, about your concerns. Don't be disappointed if you learn that this type of case is not a high priority for them.
