KEY POINTS:
Paris Hilton is "emotionally distraught and traumatised" over her 45-day jail sentence and is not capable of testifying in a civil lawsuit against her, her psychiatrist says.
Dr Charles Sophy says Hilton needs time to recover from the shock of receiving jail time before testifying in a civil case brought against her by actress and diamond heiress Zeta Graff.
Graff filed a US$10 million ($13.6 million) lawsuit against Hilton in 2005, claiming she spread "vicious lies" about her. The trial has been postponed to August.
