fractional votes

[Trina]

It was announced that it was adopted a few years ago and is being challenged now. However, there may be another factor, which is that there were only supposed to be 143 voting members, not 145, so 51% would indeed be 73.

Well, this is really quite a different issue than your original question. I think any challenge to the announced outcome of the vote on the motion would have had to be timely. This belated challenge does not fit any of the categories of what are called 'continuing breaches' (RONR 11th ed. p. 251) -- that is, errors that can be challenged by a point of order at any time. For a closely related discussion, see Official Interpretation 2006-18 (note that the reference to p. 244 in the text would change to p. 251 when referencing the newer 11th edition).
