But JTB and FIRS said the provisions of the bill that gives NIPOST the power to denote, authenticate and validate instruments, as presently drafted, was a duplication of existing legislation particularly the section 4 and 5 of the Stamp Duties Act. Speaking at a public hearing on the bill organised by the Senate Committee on Communications, the Secretary of JTB, Nana-Aisha Obomeghie, said the bill replicates and muddles provisions regarding the collection of stamp duties that are already contained in the Stamp Duties Act (SDA). Mr Gbonjubola Matthew, Coordinating Director Special Tax Operation, FIRS, said “Asking the NIPOST to be exclusively in charge of stamp duty will be against the spirit of the constitution.”
