Step 1: Understanding committal proceedings.
Section 209 CrPC deals with committal of cases to the Court of Session when it appears to be triable by the Sessions Court.
Step 2: Nature of proceedings.
Committal proceedings are not considered a trial. They are preliminary in nature and thus fall under the category of “inquiry” as defined in CrPC.
Step 3: Conclusion.
Therefore, the nature of committal proceedings under Section 209 is inquiry, not trial.
