On 19 May 2022, a three-judge bench presided by Justice Uday Umesh Lalit — through a judgment authored by Justice S. Ravindra Bhat — held that the secondment of expatriate employees by overseas group entities of *Northern Operating Systems Pvt. Ltd.* constituted a taxable supply of manpower under the Finance Act 1994, attracting reverse-charge service tax. Substance, not the form of the secondment contract, was held to govern; the employment matrix — payroll, social security, the right of repatriation — remaining with the overseas entity was decisive. The Court denied the Revenue the extended period of limitation under *Section 73*. The judgment has since travelled into the GST era through a wave of *Section 74* notices and a moderating CBIC instruction.
