FYI: Star Alliance's CEO had stated earlier this week he expected the debate over whether or not to admit Air India into Star Alliance could drag into Monday before a full vote is taken.
As of yesterday it seemed at least two airlines were dead set on vetoing Air India, with others also teetering on vetoing entry, however influence of other members could be exerted to sway votes for various reasons.
While it is now Monday in Frankfurt, we may not know the outcome until late Monday.
