To best of my knowledge, I know of no single case where evidence put in front of judge was proven to be false and misleading that wasnt dismissed as evidence or collapsed a case entirely.
Here's one for starters
Judge blasts lawyers as €300k crash claims dismissed as fraud
A judge has said some solicitors should be more selective about who they accept as clients as she dismissed five fraudulent personal injury claims for up to €300,000.

I've seen a fair few cases in the last 12 months in the papers as being thrown out, judges are being more assertive on this from what I've read. Having said that, and having been called to appear as a witness twice in the Four Courts on a claim, I remember sitting outside the courts and you couldn't help but evesdrop on some of the conversations between solicitors and clients and there is always an element of negotiation going on before it gets into court. In fairness, I presume it is cheaper for the insurance company to settle on the steps of the court then inside it from a legal cost perspective.
