The group noted that ADC was attracting growing national attention.
Mr Aregbesola, through his lawyer, Mohammed Sheriff, cited lack of confidence in the judge, in his seven-ground argument.
He said it is inconsistent to condemn electoral malpractice while also praising its efficiency in other places.
He described the ADC presidential primary election as “massively rigged.”
The meeting follows the former vice president’s visit to Mr Amaechi at his Abuja residence.
“Let me warn again that any further attempt to interfere in the affairs of the party by the presidency, INEC and judiciary will be fiercely resisted,” said Mr Abubakar.
Mohammed Hayatudeen, who also contested in the primary election, polled 177,120.
He said the results were fraudulent and concocted.
Mr Hayatu-Deen said, “I am concerned by reports from across the country of widespread vote rigging.”
