Stephen Nurrish by his tutor Janice Nurrish v Schwander  NSWSC 91 provides a useful precedent regarding the removal of a tutor. The defendant did not oppose the application.
The tutor had been necessary at the time of issue of proceedings, the claimant having suffered a stroke with consequent cognitive deficits. Expert evidence suggested that the claimant was no longer incapable of conducting his own litigation, although his recovery was not complete.
At  the court took into account the expectation that the claimant would enjoy the ongoing assistance of his wife, quite apart from his solicitor and barrister, in the proceedings; it is certainly not as if he is attempting to prosecute his claim on his own.
