Acting President Yemi Osinbajo has refused to approve four bills forwarded to the executive for assent.

Osinbajo who conveyed his decision in a letter read on the floor of the senate by Bukola Saraki on Wednesday, said assent to some of the bills was withheld due to “concerns regarding words and phrases, and the spirit behind the amendment”, and due to ” the existence of pending legal issue”.

The bills are – Dangerous Drug Amendment Bill, 2016; National Lottery Bill, 2016; Currency Conversion Freezing Order Amendment Bill, 2016, and Agricultural Credit Scheme Bill, 2016.

Speaking on the refusal of the acting president to sign the bills into law, Dino Melaye, senator representing Kogi west, however, said the executive must respect the principle of separation of powers.

Melaye said, the executive has the responsibility of assenting to bills made by the legislature or go to court to challenge them.

The senate president, Saraki on his part said, the matter would be referred to the legal department of the national assembly for advice and interpretation.
