In what scenario would the secrecy of investigation be appropriate?

Inquisitorial systems are characterized by their approach to legal proceedings, where the court or a designated authority actively investigates the facts of a case, often with limited involvement from the parties. In this context, the secrecy of investigation can be particularly appropriate to protect the integrity of the inquiry, preserve the rights of the accused, and ensure that witnesses feel safe to provide honest and complete testimonies without fear of retribution or external pressures.

This confidentiality allows investigators to work without undue influence or media scrutiny, which can sometimes affect the quality of evidence or the willingness of parties to cooperate. In many inquisitorial systems, the preliminary stages of investigation are conducted behind closed doors to maintain this integrity and ensure that the trial can proceed fairly once it is initiated.

In contrast, an open trial allows for public scrutiny, and during plea bargains or in the case of public complaints, the urgency for transparency or public accountability usually outweighs the need for secrecy. This is why the inquisitorial system stands out as a more appropriate context for maintaining the secrecy of investigations.
