It seems to me that the MDMN BOYZ empowered whoever sold the shares to be in a position to do so and I don't think an innocent buyer would just give them up or have to due to the boards negligence. I doubt his lawyer would let him.
The buyer would be in the same position as an innocent holder in due course (as in negotiable instrument law).
The shares are negotiable, just look on the reverse side of the certificate.
