They have argued that the services consumed outside India cannot be subject to GST.
The petitioners also argued that tax is discriminatory as certain hajis, who undertake the pilgrimage through the Haj Committee of India are exempted.

But, if such services are of a specific organisation facilitated by the External Affairs Ministry under a bilateral arrangement, the GST rate would be nil.
