The House of Representatives has rejected the invitations of its members by the Economic and Financial Crimes Commission (EFCC) as part of investigation into alleged padding of the 2016 appropriation bill.
In a letter to the Commission, the House informed the anti-graft agency that it has to send the investigation requests through its Speaker, Yakubu Dogara.
House Minority Leader, Leo Ogor, has refused to appear before the agency unless the condition is met.
The Minority Leader is one of about 50 lawmakers expected to appear before the agency to answer questions concerning allegations of illegally smuggling N284 billion into the 2016 budget.
Others invited include principal officers, Dogara, Ogor, Deputy Speaker, Lasun Yusuf, and House Whip Alhassan Doguwa.
Responding to the letter, the Commission said: "We have received a letter from the Clerk to the House claiming that he was directed by the Speaker to tell the EFCC that Ogor or any Representative be invited through the Speaker.
"We don’t know what informed such a notice but the Clerk was saying it is the norm. We are weighing options including exhausting all hurdles laid by the House.
"We may write the House but at the end, if Ogor and other lawmakers refuse to honour our invitation, we will effect their arrest.
"No member of the House has constitutional immunity from investigation and prosecution."
A former House Appropriation Committee Chairman, Abdulmumin Jibrin, had in a petition to the EFCC last year, alleged that lawmakers tampered with the appropriation bill. Jibril appeared last week before the EFCC on the matter.
Jibril who fell out with the leadership of the House after he made the allegations public, was subsequently suspended from attending House of Rep. sitting for 180 legislative days.
