Inquisitorial System
Definition
A model of legal proceedings, common in civil-law countries such as France and Germany, in which the court takes an active role in investigating facts. The forensic expert often serves as a court-appointed neutral rather than as a witness retained by one side, contrasting with the adversarial model used in common-law countries.

Common questions
Why does the inquisitorial model change how experts testify?+
Because the expert reports to the court rather than to a party, cross-examination is less adversarial and the expert's written report often carries more weight than oral testimony. There is less incentive to shade an opinion toward one side, but also less opportunity for a defence expert to challenge methodology directly.
Can parties still bring their own experts under an inquisitorial system?+
Many civil-law jurisdictions allow party-appointed experts alongside the court-appointed one, but the court's expert typically carries greater evidentiary weight. The balance varies by country and by whether the proceeding is criminal or civil.
Does the inquisitorial model affect disclosure of forensic methods?+
The investigating authority generally controls what evidence is gathered and how, and the defence has more limited ability to demand independent testing compared with common-law discovery rules. This shapes what a forensic report needs to document to withstand later challenge.
