Abubakar Malami, attorney-general of the federation (AGF), says the national assembly has no constitutional power to summon President Muhammadu Buhari.
Last week, the house of representatives passed a resolution summoning the president over the rising insecurity in the country.
The president is scheduled to appear before the national assembly on Thursday but it is now uncertain if he will honour the request.
In a statement on Wednesday, Malami said it was outside the constitutional powers of the national assembly to summon the president over his “operational use of the armed forces”.
“The confidentiality of strategies employed by the President as the commander in Chief of the Armed Forces of the Federal Republic of Nigeria is not open for public exposore in view of security implications in probable undermining of the war against terror.
“The fact that President Muhammadu Buhari was instrumental to the reclaiming of over 14 Local Governments previously controlled by the Boko Haram in North East is an open secret, the strategies for such achievement are not open for public expose.
According to the statement, the president’s efforts on security matters are exclusive and confidential, and as such, “the National Assembly has no Constitutional Power to envisage or contemplate a situation where the President would be summoned by the National Assembly on operational use of the Armed Forces.”
Malami added that the decision to appear before the national assembly should be at the president’s discretion and not subject to summons by the lawmakers.
“The right of the President to engage the National Assembly and appear before it is inherently discretionary in the President and not at the behest of the National Assembly,” the attorney-general said.
“As the Commander in Chief, the President has exclusivity on security and has confidentiality over security. These powers and rights he does not share. So, by summoning the President on National Security operational Matters, the House of Representative operated outside constitutional bounds.
“President’s exclusivity of constitutional confidentiality investiture within the context of the constitution remains sacrosanct.”
