The RLA is composed of three elected regional assemblymen from each of the congressional districts in Maguindanao, Lanao del Sur, Sulu, Tawi-Tawi, Basilan and Marawi City.
Insiders said the RLA now has two Speakers Maguindanaos Ibrahim Ibay and Tawi-Tawis Ismael Abubakar Jr., who took over as Speaker in an unannounced session last Monday.
Ibay and Abubakar have since been separately functioning as Speaker, even presiding over sessions of their respective blocs.
Acting on a petition of Ibays bloc, Regional Trial Court Judge Ismael Bagundang ordered Abubakar the other day to desist from discharging the functions of Speaker until next week, pending further hearings on the leadership controversy.
In a press conference, Ibay, installed as Speaker last year by 15 of the RLAs 24 members, described Abubakars takeover as illegal.
"What we are worried about is that it will (be) a very bad precedent, an example of circumvention of the RLAs operating rules just to put an assemblyman to the top position," he said.
Ibay said Abubakar and his supporters held an unscheduled session and declared the positions of Speaker and Speaker Pro Tempore vacant without any prior consultation with the other assemblymen.
Former RLA Speaker Ombra Datumanong presided over the session.
Speaker Pro Tempore Tomi Ala, whom Abubakars group replaced with Assemblyman Suharto Midtimbang (second district, Maguindanao), said that under the RLAs operating rules, an ordinary member of the assembly could only preside over a session in the absence of both the Speaker and the Speaker Pro Tempore.
Abubakar earlier said his installation as the new Speaker was in accordance with law and supported by a majority of the assemblymen.
Ibay said he is ready to relinquish his post as long as the leadership change is in accordance with the RLAs rules.
