What would be the vote required to suspend Rule 5 of the sample convention rules at 59:43, namely "Rule 5. No member shall speak in debate more than once on the same question on the same day, or longer than two minutes, without permission of the convention granted by a two-thirds vote without debate." Follow up, how does the "the general parliamentary rule normally applying to the same situation" in 59:37 apply to suspending the above referenced rule? TIA
