There is no "expulsion" here, and there is not "removal" here. Your continued use of those terms to describe a situation that involves neither is actually inviting misuse of the OSPR. We are dealing with someone ceasing to be a member of the Senate due to innactivity and such the seat becomes vacant just like the seats of Ted Kennedy, Robert Byrd, and Craig Thomas became vacant upon their sad passages. Your use of the term "expulsion" and the term "removal" are creating a false equivalency here. The real RL equalivency is death.
I agree with you on the interpretation fwiw. An inactive Senator's term essentially 'lapses'; there is no removal - it's a passive not an active dismissal from office. You are also correct in the precedent set with regards voting; the numerous Senates I've been part of have had incidents where voting is dissallowed or barred as the appropriate number of hours (or blocks of 24hrs) have not passed.
