A permanent court expert is a person who has been selected by the court as a specialist for a particular area based on experience and conscientiousness.
The court expert represents an extended arm of the court, where the court requires expert opinion from the court expert to be taken as evidence in a court case. Expertise, which is then carried out by an expert, is expert’s report ordered by a court about an event or occurance, and is related to a particular specialty (construction, telecommunications, signaling-safety devices etc.).
These kind of expert elaborates can be used as evidence in court, but can also serve as other professional needs.
