In an opinion written for the Free the Delegates group that tried to steal the nomination from Trump at the GOP convention last month, conservative parliamentarian Thomas Balch argues that the 168 members of the RNC have broad authority to recall the nominee for almost any reason.

Rule 9, which was adopted at the convention, appears to only give the RNC power to fill vacancies, not to create them.

“The Republican National Committee is hereby authorized and empowered to fill any and all vacancies which may occur by reason of death, declination, or otherwise,” the rule states.

Those trying to convince the RNC to recall Trump have had difficulty convincing members that the rule gives them the power to proactively create a vacancy on the ticket.
