(a) for the first application of subsection (2), if the application of subsection (1) resulted in the allocation to the party of a seat for the constituency, or

(b) for any subsequent application of subsection (2), if the previous application of that subsection resulted in the allocation to the party of a seat for the constituency,

and each recalculation is to be carried out under section 8(2)(b) after adding one to the previous seat allocation divisor for that party.

(7) If, on the application of subsection (1) or on an application of subsection (2), the highest seat allocation figure is the seat allocation figure for two or more parties or individual candidates (referred to in subsection (8) as the “tied seat allocation figure”), subsection (1) or (2) (as the case may be) applies to each of them.

(8) But if subsection (7) would mean that more than the full number of seats for the constituency were allocated, subsection (1) or (2) is not to be applied until—

(a) a recalculation of the seat allocation figure for any party with the tied seat allocation figure has been carried out under section 8(2)(b) after adding one to the number arrived at under section 8(2)(a), and

(b) one has been added to the number arrived at under section 8(4) for any individual candidate with the tied seat allocation figure.

(9) If, after that, the highest seat allocation figure is still the seat allocation figure for two or more parties or individual candidates (so it is still the case that more than the full number of seats for the constituency would be allocated), the constituency returning officer must decide between them by lots.”

(6) But if there is more than one person who satisfies the conditions in subsection (4), the constituency returning officer may only notify the name of whichever of them was the higher, or the highest, on the list.

(7) If there is no-one who satisfies the conditions in subsection (4), the seat remains vacant until the next general election.

(8) A person whose name is notified under subsection (3) is to be treated as having been declared to be returned as a Member of the Senedd on the day on which notification of the person’s name is received by the Presiding Officer.
