The rule makes the council outcome decisive. The mayor must be elected by Johannesburg’s City Council and take office after the specified municipal election. Pre-election temporary appointments are excluded.

The event had $118,773 in cumulative volume. These are a dated price snapshot and event-wide turnover, respectively.

The selected quote should not be treated as an exhaustive ranking of all outcomes, and each contract’s own terms remain relevant.

The useful checks are the council’s composition after the election; the recorded mayoral vote. Those checks connect the public story to the settlement condition instead of treating attention as confirmation.

That detail narrows the question being priced and is worth checking before comparing this contract with a broader political prediction.
