Delhi HC held that post-insolvency claims not part of an approved Resolution Plan under IBC stand extinguished and cannot be arbitrated. In JSW Ispat v. Bharat Petro Resources, Justice Jyoti Singh ruled that once a Resolution Plan is approved under Section 31, it binds all stakeholders, and any claims not included are legally non-arbitrable. The Court also clarified that a former NCLAT Chairperson acting as arbitrator is not disqualified merely for past judicial involvement. Upholding the “clean slate” doctrine, the Court emphasized IBC’s overriding effect under Section 238, ensuring resolution applicants are not burdened with unadjudicated liabilities. Consequently, the arbitral award of ₹12.90 crores was set aside, reinforcing the finality and supremacy of the IBC framework over other legal remedies.
