What happens if a company’s shares are recalled for voting and more shares have been sold than issued?

Google is not helping me here, so I’m hoping someone here might be able to…

What happens in the hypothetical scenario that a company:

1. announces a shareholder meeting and 60-day notice to recall shares
2. its shareholders all recall their shares so that they can vote
3. it is discovered there are not enough available shares to be recalled, due to naked short-selling/synthetic shares/failures-to-deliver?

In this scenario, what happens A) in terms of shareholders’ voting rights for the meeting, and B) for the shareholders’ portfolio positions?
