As per case facts, an investigation under the Benami Act revealed a benami transaction where a corporate debtor's shareholding was transferred to a beneficial owner. Consequently, authorities issued a provisional ... attachment order on the corporate debtor's immovable properties. Separately, the corporate debtor entered corporate insolvency resolution proceedings, leading to liquidation. The liquidator challenged the attachment, arguing it was void under the IBC moratorium and that the attached properties belonged to the liquidation estate. NCLT and NCLAT dismissed these challenges, stating they lacked jurisdiction over Benami Act proceedings. The appellants then appealed to the Supreme Court. The question arose whether the legality of a Benami Act attachment order can be challenged before IBC tribunals. Finally, the Supreme Court ruled that Benami Act proceedings, being a sovereign penal action for confiscation *in rem*, fall outside IBC tribunals' jurisdiction. The NCLT cannot review such sovereign actions, and properties attached under the Benami Act vest in the Central Government, hence not part of the liquidation estate. The IBC moratorium doesn't shield "tainted assets" from sovereign actions. Therefore, the appeals were dismissed with costs.
