In this Part "the requisite majority of qualifying tenants of the constituent flats" means qualifying tenants of constituent flats with more than 50 per cent. of the available votes.
The total number of available votes shall be determined as follows—
where an offer notice has been served under section 5, that number is equal to the total number of constituent flats let to qualifying tenants on the date when the period specified in that notice as the period for accepting the offer expires;
where a notice is served under section 11A without a notice having been previously served under section 5, that number is equal to the total number of constituent flats let to qualifying tenants on the date of service of the notice under section 11A;
where a notice is served under section 12A, 12B or 12C without a notice having been previously served under section 5 or section 11A, that number is equal to the total number of constituent flats let to qualifying tenants on the date of service of the notice under section 12A, 12B or 12C, as the case may be.
There is one available vote in respect of each of the flats so let on the date referred to in the relevant paragraph of subsection (2), which shall be attributed to the qualifying tenant to whom it is let.
The persons constituting the requisite majority of qualifying tenants for one purpose may be different from the persons constituting such a majority for another purpose.
