The Bombay High Court has granted interim protection from prosecution and penalty to industrialist Anil Ambani in an alleged tax evasion case, while admitting his petition challenging the constitutional validity of provisions of the Black Money Act. According to reports from PTI, a division bench of Justices B P Colabawalla and Firdosh Pooniwalla heard the matter on Tuesday, June 10, 2026, and noted that there are other petitions filed in HC against the Act. The court has specifically clarified that 'no coercive action shall be taken against the petitioner, including that of prosecution and penalty, till the hearing and final disposal of this writ petition'. As per Mid-day, the court stated that Ambani cannot be prosecuted or penalised under the Act until the High Court decides the constitutional challenge.
The Income Tax department issued a notice to Ambani on August 8, 2022, for allegedly evading ₹420 crore in taxes on undisclosed funds of more than ₹814 crore held in two Swiss bank accounts. As per the department's notice, Ambani was liable to be prosecuted under Sections 50 and 51 of the Black Money Act, which stipulates a maximum punishment of 10 years imprisonment with a fine. The department has charged Ambani with 'wilful' evasion, claiming he 'intentionally' did not disclose his foreign bank account details and financial interests to Indian tax authorities. According to PTI, Ambani in his petition claimed that the Black Money Act was enacted in 2015, and the alleged transactions are of assessment years 2006-2007 and 2010-2011, arguing that the provisions cannot have a retrospective effect.
Ambani, in his plea, said certain provisions of the (Undisclosed Foreign Income and Assets) and Imposition of Tax Act, 2015, were 'ultra vires' (beyond the powers/violative) to the Constitution of India. According to PTI, the HC noted that an assessment order against Ambani has already been passed and that he has filed an appeal before the Commissioner of Income Tax (Appeals). The court directed the Union government to file its affidavit in response to the plea, with the HC observing that 'the said appeal can proceed and orders can be passed thereon' while maintaining the interim protection. The court also noted that similar petitions challenging the Act are already pending before it and admitted Ambani's plea for detailed consideration at a later stage.
According to the I-T department's notice, Ambani was an 'economic contributor as well as beneficial owner' of a Bahamas-based entity called 'Diamond Trust' and another company called Northern Atlantic Trading Unlimited (NATU), which was incorporated in the British Virgin Islands (BVI). The department alleged that Ambani 'failed to disclose' these foreign assets in his income tax return (ITR) filings and hence contravened provisions of the Black Money Act. The total value of the undisclosed funds in the two accounts has been assessed by tax officials at ₹8,14,27,95,784, and tax payable on this amount at ₹4,20,29,04,040. As per Mid-day, the department alleges that these interests were not disclosed in his income tax returns, thereby violating provisions of the Black Money Act.
