i should also comment that once a Scheme passes at the EGM (ie they get their requisite 75% of sh and shares who vote "YES"), the coy LLP, then has to get Court approval.

Any s/h can attend court and object to the Court giving its approval.
Usually if the vote is approved by the 75% or more, one would expect the Cort to approve. But if a sh presented to the Court evidence as to why the Court should not approve the Scheme, the Court could throw out the Scheme.
Objections could be voting irregularities, meeting not called properly, issues with Experts Reports etc etc.
