The Network for the Actualization of Social Growth and Viable Development (NEFGAD), a frontline civic advocacy group in Nigeria, has written to President Bola Ahmed Tinubu and the National Assembly, demanding an immediate and independent investigation into alleged unlawful alterations to Nigeria’s newly gazetted tax laws.

In a letter signed by the group’s acting head of office, Barr. Blessing Nnekwu Ojo, NEFGAD expressed grave concern following the National Assembly’s confirmation that changes were made to the contents of tax laws after they had been duly passed and assented to by the president.

The organization described the development as a direct assault on constitutional order, legislative integrity, and democratic governance.

The letter called on President Tinubu to immediately order an independent investigation to determine the point at which the integrity of the legislative process was compromised, establish the exact nature and scope of the alterations, and apply appropriate sanctions to all persons, offices, or agencies involved, in accordance with the Constitution and extant laws of the Federation.

According to NEFGAD, a law passed by the National Assembly represents the final and authoritative expression of legislative intent.

The group said any alteration—whether by omission, substitution, or addition—amounts to a fundamental breach of due process, public trust, and the rule of law.

It also undermines the doctrine of separation of powers, erodes confidence in Nigeria’s law-making process, threatens fiscal certainty, weakens investor confidence, and poses reputational risks to the country and the current administration.

NEFGAD further warned that failure to take prompt corrective action would leave the organization with no option but to seek judicial redress, including instituting proceedings before the ECOWAS Community Court of Justice over issues relating to legislative impunity, institutional abuse, and denial of the rule of law.

“This matter is not merely administrative; it is constitutional and existential to Nigeria’s democracy. The nation expects decisive action, transparency, and accountability,” the group emphasised.

NEFGAD reaffirmed its commitment to defending democratic institutions, upholding the rule of law, and ensuring that Nigeria’s governance processes remain credible, lawful, and transparent.
