A more thorough explanation:

Open court refers to legal proceedings that are open to the public. This means that anyone can attend the court proceedings, access court records, and read transcripts of the proceedings. However, if a case involves sensitive or private information, the proceedings may be held in camera, which means they are held in the judge's private chambers and are not open to the public.

For example, in Connecticut, if a case involves the disclosure of confidential HIV-related information, the proceedings must be held in camera unless the person who is the subject of the test agrees to a public hearing or the court determines that a public hearing is necessary for the public interest and the proper administration of justice.

Another example of when a court proceeding may be held in camera is in cases involving minors. The court may decide to close the proceedings to the public to protect the privacy of the child.

The principle of open court is important because it ensures transparency and accountability in the legal system. It allows the public to observe the proceedings and ensures that justice is being served fairly and impartially.
