Godswill Akpabio announced as the Senate Minority leader.

I thought Godswill Akpabio,the immediate ex Governor of Akwa Ibom state, was going to be investigated with all the corruption allegations going on,his fellow south south lawmakers in my opinion suggests,they have appointed somebody who will protect them,especially as it is 
said that his nomination in the first place was against the rules.

His nomination is against the rules of the senate that exempts first time senators from becoming Senate Minority leaders. He was nominated by the South South Senators in the Senate. Senator Emmanuel Bwacha was named Deputy Minority Leader, Senator Philip Aduda becomes Minority Whip and Senator Bioudun Olujimi is Deputy Minority Whip.
What i don't understand is this,if his nomination was against the rules,why was he allowed to be nominated then? I just don't get that,if you are not legible,why are you allowed to participate? Another Nigerian riddle for you there...
