President Muhammadu Buhari has rejected the amendment to the Electoral Act, which meant to change the country's elections sequence, Daily Trust has learnt.
The amendment re-ordered the sequence of elections with the national assembly elections coming first, governorship and state houses of assemblies second while the presidential elections last.
President Muhammadu Buhari declined assent to the amendment citing probable infringement of the Constitution.
Following its passage, some senators led by Senator Abdullahi Adamu, stormed out of the chamber to fault the amendment.
The statement said: "As a party, we are not afraid of the 2019 general elections because we know that Nigerians have already rejected President Buhari and his dysfunctional All Progressives Congress (APC)".
The two presiding officers are expected to read the letters to their colleagues at plenary between Tuesday, March 13 and Thursday, March 15.
He revealed this while giving his remarks on Monday at the Public Hearing of a Bill for an Act to Establish the National Electoral Offences Commission (NEOC).
"The amendment to section 152 (325) of the Principal Act may raise constitutional issues over the competence of the National Assembly to legislate over Local Government elections".
"Please accept Distinguished Senators, the assurances of my highest consideration".
A similar letter was also sent to the Speaker of House of Representatives, Yakubu Dogara.
It is not yet clear the next line of action of the lawmakers. "I therefore urge you to make your submissions as a way of helping us along in this process".
