Section 5 of the Arbitration and Conciliation Act sets a single, narrow test for when a court may step into arbitral proceedings, so each option can be measured directly against that test.
- When both parties request supervision of proceedings: The parties' mutual wish for court supervision does not itself create jurisdiction for a court to intervene; Section 5 ties intervention to what the Act expressly permits, not to what the parties might jointly prefer, so consent alone cannot expand the court's role beyond the Act's own provisions.
- When procedural irregularity is alleged without specific provision under the Act: An allegation of some procedural irregularity, without there being a specific provision in the Act authorising the court to step in for that irregularity, does not meet the Section 5 test; the section is deliberately worded to exclude intervention on general or unlisted grounds.
- When the court considers the award unjust on facts: A court's own view that an award is factually unjust is not, by itself, a ground for intervention under Section 5; arbitration is designed to give the arbitral tribunal the final say on facts, and a court cannot re-open that assessment merely because it might have decided the facts differently.
- When the Act expressly permits such intervention: Section 5 restricts judicial authorities from intervening in matters governed by Part I of the Act except where such intervention is expressly provided for. This means the only valid trigger for court involvement is a specific, named provision in the Act itself, such as the provisions allowing appointment of arbitrators, interim measures, or setting aside an award.
Since Section 5 permits intervention only where the Act itself expressly says so, and none of party consent, an unlisted procedural complaint, or a court's own view of factual unfairness qualifies as an express statutory permission, the matching option is the one built around express statutory authorisation.
The correct answer is therefore when the Act expressly permits such intervention.
