Suspention is different. A suspended MP is not allowed to take part in the parliamentry proceedings, but they have a right to vote for or against a motion in the parliament. All the MPs who are currently under suspention, is going to come back. All those are in the jail or out in bail, because a person remains a MP till the re election in his constituency. So all of them technically can take part in voting, now making arrangements to get them out to vote, that is correct or not is a seperate issue.
