GANGTOK, 17 Aug: Sikkim Pradesh Congress Committee has demanded that the SDF Government bring a Bill in the State Legislative Assembly to revoke the repealed Sikkim Income Tax Manual of 1948 arguing that only this would “provide solace” to the people of Sikkim including members of old business community. Article 371F of the Constitution should be invoked to pass the bill in the Assembly, an SPCC press release issued today.
