AMICUS
a growing consortium of forensic psychiatrists
WELCOME TO AMICUS
your direct link to experts in forensic psychiatry

Amicus is a growing consortium of forensic psychiatrists providing an 
easy link between barristers and expert witnesses and report writers
 in the field of psychiatry. Members are chosen for experience and
 excellence in their chosen area and adherence to the Code of Conduct
 for Expert Witnesses set out in the Judicature Act 1908. Typical areas 
of expertise include Court reports relating to fitness to stand trial
 and the insanity defence, however a wide range of other mental health 
factors may have a bearing on Court processes, both civil and
criminal.

Our members have experience in Youth, District, Family and 
High Court jurisdictions as well as the appellate Courts. A number of 
civil forensic needs including immigration reports and worker’s
 compensation are available. As with all expert witnesses, our primary
 duty is to the Court, and we work to provide unbiased information in
 accordance with national and international standards.
