NEW DELHI: Hit-run driver Puneet Puneet's long extradition case has been drawn out again after he and his lawyer failed to obey a court order to obtain an official psychiatric assessment.

The judge for Tuesday's hearing in India's capital was aghast after learning that Puneet, 29, and his counsel had ignored her "black-and-white" instructions.

In July, Puneet’s counsel Kanhaiya Kumar Singhal had insisted that Puneet had the right to be assessed by a panel of psychiatrists to prove his claim of being mentally unfit and consequently be unable to be extradited to Australia.

During the July hearing, Singhal variously claimed that Puneet suffered from multiple diseases and was also a schizophrenic who has attempted suicide.
