Under Section 2(p) of the Industrial Relations Code, 2020, which of the following is expressly excluded from the definition of "industry"?

Section 2(p) of the Industrial Relations Code, 2020 defines "industry" broadly as any systematic activity carried on by cooperation between an employer and worker for the production, supply, or distribution of goods or services with a view to satisfying human wants or wishes, irrespective of whether capital has been invested for that purpose, and regardless of whether such activity is carried on with a profit motive. However, the definition expressly excludes institutions owned or managed by organisations wholly or substantially engaged in any charitable, social, or philanthropic service, along with sovereign functions of the appropriate Government (including defence research, atomic energy, and space activities) and any domestic service. This exclusion, drawing on the framework laid down by the Supreme Court in Bangalore Water Supply and Sewerage Board v. A. Rajappa, ensures that genuinely non-commercial charitable institutions remain outside the Code's industrial relations machinery.
