Buhari economist backs decision withhold assent 2016 appropriation bill

It appears you're referring to a news article or statement made by an economist who supports President Muhammadu Buhari's decision to withhold assent to the 2016 Appropriation Bill.

For context, the 2016 Appropriation Bill was a budget proposal submitted to the Nigerian President by the National Assembly, which was expected to outline the country's expenditure plans for the year. However, President Buhari declined to sign the bill into law, citing concerns over the budget's lack of transparency and the need for further review.

The economist, who is likely a supporter of President Buhari's administration, may have argued that the President's decision was justified given the concerns over the budget's transparency and the need for fiscal responsibility. They may have also highlighted the importance of ensuring that the country's budget is managed effectively and efficiently to achieve its development goals.
