Step 1: Understanding reference jurisdiction.
Under Section 113 of the Code of Civil Procedure (CPC), a subordinate court may refer a case to the High Court during the pendency of proceedings, but only when a question of law is involved. This is because the High Court has the authority to clarify doubtful legal provisions.
Step 2: Analyzing the options.
- (A) Correct: Reference can only be made when a question of law arises.
- (B) Wrong: Questions of evidence are decided by the trial court itself.
- (C) Wrong: Questions of fact are within the domain of the subordinate court.
- (D) Wrong: Procedural issues do not require a reference.
Step 3: Conclusion.
Therefore, the correct option is (A) — a reference can be made to the High Court only on a question of law.
