I still 100% believe Luke is guilty. However, people thinking this will help her in front of a judge are kidding themselves. Perjury is a big deal and not taken lightly, and will make it very easy for Luke's lawyer to cast a lot of doubt on anything she claims or testifies, and even call her character into question. I don't see this doing anything for her case in a court of law
She could still win, she has a good lawyer and if they deliver on evidence and others coming forward, they'll be aces. But this will not help her, not one bit.
