A Delhi landlord, busy caring for his ailing father, missed the deadline to e-verify his income tax return, leading to a denied Rs 17 lakh refund. The Income Tax Appellate Tribunal (ITAT) Delhi intervened, ruling that withholding the refund on a technicality would amount to unjust enrichment. The tribunal emphasized that tax can only be collected by law, allowing the landlord to claim his rightful refund.
