I agree that so far as we know Jagdeo has never appeared in court for his crimes.
As a sop the cult, in the form or Elan Vital, did apparently initiate legal proceedings against Jagdeo. However we never heard what further actions, if any, occurred on these apparent legal proceedings and it certainly is the responsibility of Elan Vital to update the world on what happened. I rather suspect that Elan Vital quietly dropped their action in the hope that it all would be forgotten about quietly, seeing that the Jagdeo issue, in the same vein as the Indian bicycle accident, still has such an explosive impact on Prem Rawat's reputation.
Anyway, here is a copy of Elan Vital announcement of them taking legal action against Jagdeo which is linked from this page.
