Yes, they have started speaking!
Two spoke recently:
New York Times: NIGERIA, Oct. 10 â€” A judge in the northern state of Kogi has ordered a rerun of the election for governor that took place in April, ruling in favor of an opposition candidate who argued that the polls were so marred by fraud and violence that the results lacked legitimacy.
… Kebbi state:
“State election petition tribunal yesterday nullified election of Senator Tanko Ayuba, representing Kebbi South Senatorial District in the National Assembly, and ordered for a bye-election.”
And more will speak before the end of the month – in Ondo state particularly. The legal battles have been fierce in Edo and Osun states as well.
