Perhaps those novels have Sci
, but as we all know novels are non-canon. From a strict canon point of view we know virtually nothing about how the Federation works as a political body.
A presidential veto could be considered undemocratic as one person can override a majority vote. Even if it goes back at what level do you set a council override of a presidential veto?
50%+1, 66% ?
Clearly the threshold to override the veto has to be +1
I.e If the Federation Council is made up of 150 councillors and a vote to override a veto goes along the lines of 75 yes, 74 no, with one abstention. Then in a democracy as more people have voted in favour then the motion should carry. Which kind of defeats the purpose of vetoing a bill which has passed.
