Reverse charge liability for arbitral tribunal services shifts to business recipients under service tax regime. Reverse charge applies to services provided or agreed to be provided by an arbitral tribunal, shifting full service tax liability to the business entity recipient located in the taxable territory; the service provider bears no tax under the specified notification. 'Business entity' covers persons ordinarily engaged in industry, commerce or any business or profession, and 'arbitral tribunal' means a sole arbitrator or panel of arbitrators as defined in the Arbitration and Conciliation Act.
